During major long-term crises, such as the COVID-19 pandemic, news media are crucial sources of information for the public. This study aimed to explore the frequency of COVID-19-related news consumption based on (1) phase of the pandemic, (2) socio-demographic characteristics, and (3) news information channels. The study used a dynamic cohort design with 18 rounds of data collection, including 306,692 responses from 83,180 unique respondents in the Netherlands from 17 April 2020 to 11 September 2022. Results showed that the frequency of general COVID-19-related news media consumption varied throughout the pandemic, following a general decreasing trend with relative spikes often coinciding with periods of stricter behavioural regulations. TV news, newspapers, and online news websites were the most popular news information channels among the respondents. Furthermore, multilevel regression analyses identified several socio-demographic factors influencing news consumption and preferred channels, namely age, migration background, living status, health status, and trust in government — these results remained stable throughout the pandemic. This study highlights the importance of selecting appropriate news channels to effectively reach different socio-demographic groups and shows that during a prolonged crisis, news consumption about the crisis fluctuates with worsening conditions but generally follows a decreasing trend.

Backgrounds: Most countries are facing increased pressure on healthcare resources. A better understanding of how healthcare providers respond to new demands is relevant for future pandemics and other crises. Objectives: This study aimed to explore what nurses and doctors in Norway reported as their main ethical challenges during two periods of the COVID-19 pandemic: February 2021 and February 2022. Research design: A longitudinal repeated cross-sectional study was conducted in the Western health region of Norway. The survey included an open-ended question about ethical challenges among doctors and nurses in hospital departments. Free-text comments were analysed using Systematic Text Condensation and also presented in a frequency table. Ethical considerations: Ethical approval was granted by the Regional Research Ethics Committee in Western Norway (131,421). All participants provided consent when participating in the study. Results: In 2021, 249 and in 2022, 163 healthcare professionals responded to the open-ended question. Nurses and doctors reported three main categories of ethical challenges related to the COVID-19 pandemic: (1) barriers that hindered them in acting as they ethically would have wanted to do; (2) priority-setting dilemmas linked to overtreatment, transfer of resources and ranking patient needs; and (3) workload expansion threatening work–life balance and employees' health. Category one comprised of resource barriers, regulatory barriers, system barriers, and personal barriers. Regulatory barriers, especially visitor restrictions for next-of-kin, were the most frequently reported in 2021. Resource barriers, related to the increased scarcity of qualified staff, were most frequently reported in 2022. Clinicians stretched themselves thin to avoid compromising on care, diagnostics, or treatment. Conclusions: Developing clinicians' ability to handle and cope with limited healthcare resources is necessary. To foster resilience and sustainability, healthcare leaders, in collaboration with their staff, should ensure fair priority-setting and initiate reflections among doctors and nurses on what it implies to provide 'good enough' care.

Introduction: The COVID-19 pandemic exacerbated healthcare needs and caused excess mortality, especially among lower socioeconomic groups. This study describes the emergence of socioeconomic differences along the COVID-19 pathway of testing, healthcare use and mortality in the Netherlands. Methodology: This retrospective observational Dutch population-based study combined individual-level registry data from June 2020 to December 2020 on personal socioeconomic characteristics, COVID-19 administered tests, test results, general practitioner (GP) consultations, hospital admissions, Intensive Care Unit (ICU) admissions and mortality. For each outcome measure, relative differences between income groups were estimated using log-link binomial regression models. Furthermore, regression models explained socioeconomic differences in COVID-19 mortality by differences in ICU/hospital admissions, test administration and test results. Results: Among the Dutch population, the lowest income group had a lower test probability (RR = 0.61) and lower risk of testing positive (RR = 0.77) compared to the highest income group. However, among individuals with at least one administered COVID-19 test, the lowest income group had a higher risk of testing positive (RR = 1.40). The likelihood of hospital admissions and ICU admissions were higher for low income groups (RR = 2.11 and RR = 2.46, respectively). The lowest income group had an almost four times higher risk of dying from COVID-19 (RR = 3.85), which could partly be explained by a higher risk of hospitalization and ICU admission, rather than differences in test administration or result. Discussion: Our findings indicated that socioeconomic differences became more pronounced at each step of the care pathway, culminating to a large gap in mortality. This underlines the need for enhancing social security and well-being policies and incorporation of health equity in pandemic preparedness plans. [ABSTRACT FROM AUTHOR]

Development of broad-spectrum antiviral therapies is critical for outbreak and pandemic preparedness against emerging and reemerging viruses. Viruses inducing hemorrhagic fevers cause high morbidity and mortality in humans and are associated with several recent international outbreaks, but approved therapies for treating most of these pathogens are lacking. Here, we show that 4′-fluorouridine (4′-FlU; EIDD-2749), an orally available ribonucleoside analog, has antiviral activity against multiple hemorrhagic fever viruses in cell culture, including Nipah virus, Crimean-Congo hemorrhagic fever virus, orthohantaviruses, and arenaviruses. We performed preclinical in vivo evaluation of oral 4′-FlU against two arenaviruses, Old World Lassa virus (LASV) and New World Junín virus (JUNV), in guinea pig models of lethal disease. 4′-FlU demonstrated both advantageous pharmacokinetic characteristics and high efficacy in both of these lethal disease guinea pig models. Additional experiments supported protection of the infected animals even when 4′-FlU delivery was reduced to a low dose of 0.5 milligram per kilogram. To demonstrate clinical utility, 4′-FlU treatment was evaluated when initiated late in the course of infection (12 or 9 days after infection for LASV and JUNV, respectively). Delayed treatment resulted in rapid resolution of clinical signs, demonstrating an extended window for therapeutic intervention. These data support the use of 4′-FlU as a potent and efficacious treatment against highly pathogenic arenaviruses of public health concern with a virus inhibition profile suggesting broad-spectrum utility as an orally available antiviral drug against a wide variety of viral pathogens. Editor's summary: There are no approved therapies for pathogenic hemorrhagic fever viruses, such as Lassa virus or Junín virus, that cause high morbidity and mortality in humans. Welch et al. now report that 4′-fluorouridine (4′-FlU; EIDD-2749), an oral ribonucleoside analog, has potent antiviral activity against pathogenic hemorrhagic fever viruses in vitro. When given orally to infected guinea pigs, 4′-FlU protected the animals against lethal disease due to Lassa virus or Junín virus. Protection was seen even with reduced doses of drug and when treatment was started after the onset of clinical disease signs. These findings suggest that further investigation into 4′-FlU as a potential treatment for arenavirus infections is warranted. —Orla Smith [ABSTRACT FROM AUTHOR]

Understanding the zoonotic risks posed by bat coronaviruses (CoVs) is critical for pandemic preparedness. Herein, we generated recombinant vesicular stomatitis viruses (rVSVs) bearing spikes from divergent bat CoVs to investigate their cell entry mechanisms. Unexpectedly, the successful recovery of rVSVs bearing the spike from SHC014-CoV, a SARS-like bat CoV, was associated with the acquisition of a novel substitution in the S2 fusion peptide-proximal region (FPPR). This substitution enhanced viral entry in both VSV and coronavirus contexts by increasing the availability of the spike receptor-binding domain to recognize its cellular receptor, ACE2. A second substitution in the S1 N–terminal domain, uncovered through the rescue and serial passage of a virus bearing the FPPR substitution, further enhanced spike:ACE2 interaction and viral entry. Our findings identify genetic pathways for adaptation by bat CoVs during spillover and host-to-host transmission, fitness trade-offs inherent to these pathways, and potential Achilles' heels that could be targeted with countermeasures. Author summary: The recent emergence of several highly virulent human coronaviruses, SARS-CoV, MERS-CoV and SARS-CoV-2, underscores the risk coronaviruses can pose to the human population. Bat coronaviruses (CoVs) are of particular concern due to their potential to adapt to new hosts. Here, we attempted to generate recombinant vesicular stomatitis viruses (rVSVs) bearing the spike glycoproteins from several SARS-like bat CoVs to study their cell entry mechanisms. We identified two mutations in the SHC014-CoV spike that afforded successful recovery of an rVSV bearing this spike by greatly increasing viral entry. Interestingly, these mutations occur outside the receptor-binding domain (RBD) but enhance spike-receptor interaction nevertheless. These and other results herein establish that these mutations serve to "open" the spike and thereby augment virus-receptor engagement. Our work uncovers new genetic pathways that could contribute to the adaptation of bat CoVs during host spillover. However, these mutations also render the spike more susceptible to neutralizing antibodies that recognize the RBD, pointing to fitness tradeoffs associated with these pathways.

Background: The German College of General Practitioners and Family Physicians (DEGAM) issued a COVID-19 guideline with eleven recommendations to support primary care services during the pandemic. Their use in general practices beyond the pandemic can contribute to pandemic preparedness. This study analysed general practitioners' (GPs) interest in applying recommended organisational changes in non-pandemic times. Methods: Data from the German egePan GP survey (n = 516 GPs) - a multi-level clustered randomised web-based survey - were analysed. GPs' interest in the future application of the eleven guideline recommendations was calculated. In addition, each recommendation was evaluated by the GPs using a Net-Promoter-Score (NPS range − 100 to 100). A linear regression model identified GP and practice characteristics associated with a higher interest in applying recommendations in non-pandemic times. Results: 98.5% of the GPs indicated the intention to implement at least one guideline recommendation prospectively: disinfectant dispensers at the entrance (86%), optimised consultation scheduling to reduce waiting times (83%), and glass screens in the reception area (72%), which also received the highest NPS scores. In contrast, lower interest was observed for items such as insurance card readers handled by patients (48%), only selected staff treating infectious patients (44%), and video consultations for patients with infections (26%). A higher interest to implement recommendations in non-pandemic times was associated with a higher crisis leadership score (p < 0.001), using the Corona-Warn-App (p = 0.007), and being a female GP (p = 0.045). In addition, GPs from Western, Northern, and Southern, and those with a higher patient volume per three months, were more interested in future implementation. Conclusions: Overall, GPs demonstrated the readiness to follow the DEGAM COVID-19 guideline outside pandemic periods, establishing them as key contributors to pandemic preparedness in Germany.

Background: Borneo, the third largest island in the world, is facing a significant burden of emerging and re-emerging vector-borne diseases due to rapid changes in primary tropical rainforests and urban landscapes. These vector-borne diseases include the endemic epidemic cycles that occur in the more populated and urbanized areas, as well as the possible transmission through enzootic and sylvatic transmission cycles that occur mainly in the overlapping landscapes or among the indigenous population in the forest. The island will be changed significantly in the future due to the increase in human activities, especially mega events such as the relocation of the Indonesian capital to Nusantara in East Kalimantan Borneo, increasing urbanization, agriculture, hydropower projects, ecotourism activities in Sabah, North Borneo, and Sarawak, Central and South Borneo. Therefore, an overview of the current situation of vector-borne diseases is crucial for the next possible epidemic preparedness. Methods: This study conducted the PRISMA-ScR scoping review and formulated a set of research questions to identify current trends in vector-borne diseases in Borneo. These questions aim to identify which diseases have been studied, what geographical areas have been covered by the research, how the One Health approach—encompassing human, animal and environmental factors—is integrated, and what gaps and challenges exist in addressing these diseases. Results: A total of 2241 references were screened for eligibility and 117 articles were selected for review. The majority of the materials focused on mosquitoes and malaria, and the One Health elements focused mainly on humans. Conclusions: This review has identified the most and least studied vector-borne diseases and highlighted some of the gaps in knowledge and research on vector-borne diseases on the island of Borneo. Future studies should particularly focus on other neglected diseases such as Zika, chikungunya, Japanese encephalitis, filariasis and tick-borne diseases. In addition, advanced surveillance systems will be developed to improve early detection and response specifically for remote regions where vector-borne diseases are endemic or emerging.

Background: The COVID-19 pandemic led to significant excess mortality in 2020 in Belgium. By using microlevel cause-specific mortality data for the total adult population in Belgium in 2020, three outcomes were considered in this study aiming at predicting sociodemographic (SD) and socioeconomic (SE) patterns of (1) COVID-19 specific death compared to survival; (2) all other causes of death (OCOD) compared to survival; and (3) COVID-19 specific death compared to all OCOD. Methods: Two complementary statistical methods were used. First, multivariable logistic regression models providing odds ratios and 95% confidence intervals were fitted for the three study outcomes. In addition, we computed conditional inference tree (CIT) algorithms, a non-parametric class of classification trees, to identify and rank by significance level the strongest predictors of the three study outcomes. Results: Older individuals, males, individuals living in collectivities, first-generation migrants, and deprived SE groups experienced higher odds of dying from COVID-19 compared to survival; living in collectivities was identified by the CIT as the strongest predictor followed by age and sex. Education emerged as one of the strongest predictors for individuals not living in collectivities. Overall, similar patterns were observed for all OCOD except for first- and second-generation migrants having lower odds of all OCOD compared to survival; age group was identified by the CIT as the strongest predictor. Older individuals, males, individuals living in collectivities, first- and second-generation migrants, and individuals with lower levels of education had higher odds of COVID-19 death compared to all OCOD; living in collectivities was identified by the CIT as the strongest predictor followed by age, sex, and migration background. Education and income emerged as among the strongest predictors among individuals not living in collectivities. Conclusions: This study identified important SD and SE disparities in COVID-19 mortality, with living in collectivities highlighted as the strongest predictor. This underlines the importance of implementing preventive measures, particularly within the most vulnerable populations, in infectious disease pandemic preparedness to reduce virus circulation and the resulting lethality.

Tools for rapid identification of novel and/or emerging viruses are urgently needed for clinical diagnosis of unexplained infections and pandemic preparedness. Here we developed and clinically validated a largely automated metagenomic next-generation sequencing (mNGS) assay for agnostic detection of respiratory viral pathogens from upper respiratory swab and bronchoalveolar lavage samples in <24 h. The mNGS assay achieved mean limits of detection of 543 copies/mL, viral load quantification with 100% linearity, and 93.6% sensitivity, 93.8% specificity, and 93.7% accuracy compared to gold-standard clinical multiplex RT-PCR testing. Performance increased to 97.9% overall predictive agreement after discrepancy testing and clinical adjudication, which was superior to that of RT-PCR (95.0% agreement). To enable discovery of novel, sequence-divergent human viruses with pandemic potential, de novo assembly and translated nucleotide algorithms were incorporated into the automated SURPI+ computational pipeline used by the mNGS assay for pathogen detection. Using in silico analysis, we showed that after removal of all human viral sequences from the reference database, 70 (100%) of 70 representative human viral pathogens could still be identified based on homology to related animal or plant viruses. Our assay, which was granted breakthrough device designation from the US Food and Drug Administration (FDA) in August of 2023, demonstrates the feasibility of routine mNGS testing in clinical and public health laboratories, thus facilitating a robust and rapid response to the next viral pandemic. Metagenomic next-generation sequencing has the potential to support diagnosis of unknown infections as it can identify all potential pathogens without requiring a prior suspected cause. Here, the authors develop and clinically validate a metagenomics-based assay for common and novel respiratory viral pathogens. [ABSTRACT FROM AUTHOR]

Background: The COVID-19 pandemic disrupted immunisation programs worldwide, reversing gains that had brought vaccine-preventable diseases largely under control. This study explored the impact of COVID-19 on the uptake of routine child immunisation services in South Africa. Methods: We conducted qualitative research using in-depth interviews with 51 purposively selected parents/caregivers of children below the age of five who missed or delayed one or more scheduled immunisation doses in 2020–2022 and with 12 healthcare providers who provided public immunisation services during the pandemic. Results: During the pandemic lockdowns, most caregivers perceived the risk of their child being infected with COVID-19 during a clinic visit as more salient than the risk of missing immunisation doses. Caregivers reported minimal exposure to routine immunisation communication, as well as shortages of routine vaccines for children at public health facilities, healthcare workers experienced anxiety and burnout. There was a post-pandemic shift to more active decision-making about immunisation, which had previously been an almost automatic behaviour, leading some caregivers to delay vaccinating their children. There was also evidence of a "bad vaccine" mental model among some caregivers regarding COVID vaccinations, which could lead to doubts about the safety of routine childhood vaccinations. Discussion: The shift from default to active decision-making highlights a risk that routine immunisation will backslide in future pandemics. Governments should build resilient health systems at all levels and communicate clearly about the benefits and availability of RIs and the safety of vaccinations in general, alongside supply-side interventions. Conclusion: Routine immunisation is widely accepted in South Africa, driven by generational norms and provider recommendations. During the COVID-19 pandemic, many caregivers faced the dilemma of balancing COVID-19 exposure risk with the risk of their child developing a deadly VPD, leading to missed RI visits. This shift to active decision-making highlights a future pandemic risk. Governments should build resilient health systems and focus on understanding and engaging procrastinating and doubtful caregivers. Clear communication about RI benefits and vaccine safety is crucial, as misinformation can lead to distrust in new vaccines. [ABSTRACT FROM AUTHOR]

Objectives: Disruptive public health risks and events, including infectious disease outbreaks, are inevitable, but their effects can be mitigated by investing in prevention and preparedness. We assessed the epidemic preparedness and response capacities of health systems in 186 countries from 2018 to 2022. Methods: We utilized data from the International Health Regulations (IHR) State Party Self-Assessment Annual Reporting (SPAR) submissions to assess health systems' IHR capacities to (1) prevent, (2) detect, (3) respond, (4) enable resources and coordinate, and (5) ensure operational readiness from 2018 to 2022. We categorized the IHR capacities into five levels, with level 1 denoting the lowest level of national capacity and level 5 the highest. We calculated each index's capacity level as the arithmetic mean of its related indicators and analyzed changes over time using the Mann–Kendall nonparametric trend test. Results: SPAR reporting marginally improved from 92.9% (182 of 196 countries) in 2018 to 94.9% (186 of 196 countries) in 2022, with considerable improvement in all five capacity domains over this period: prevention (58.4 in 2018 to 66.5 in 2022), detection (74.7 to 78.3), response (56.5 to 67.8), enabling resources and coordination (63.0 to 68.3), and ensuring operational readiness (62.8 to 69.9). From the 2022 submissions, 116 (62%) countries reported functional (Level 4 or 5) prevention capacity, 162 (87%) had functional detection capacity, 118 (63%) had functional response capacity, 121 (65%) had functional enabling resources and coordination capacity, and 133 (72%) had functional operational readiness against public health events. Across all the indexes, the WHO African Region reported the fewest countries with functional capacity in these domains. Conclusions: There was an overall increase in functional capacity across all five domains at both global and regional levels; and a high percentage of countries achieved functional capacity across all domains in 2022. However, a significant number of countries, particularly in the Global South, have yet to achieve functional competence in these capacities, leaving the world vulnerable to the persistent risk of epidemics and infectious biohazards. Strengthening IHR competencies through local, national, and global engagements must be urgently prioritized to achieve global health security against infectious diseases. [ABSTRACT FROM AUTHOR]

The continued emergence of deadly human coronaviruses from animal reservoirs highlights the need for pan-coronavirus interventions for effective pandemic preparedness. Here, using linking B cell receptor to antigen specificity through sequencing (LIBRA-seq), we report a panel of 50 coronavirus antibodies isolated from human B cells. Of these, 54043-5 was shown to bind the S2 subunit of spike proteins from alpha-, beta-, and deltacoronaviruses. A cryoelectron microscopy (cryo-EM) structure of 54043-5 bound to the prefusion S2 subunit of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike defined an epitope at the apex of S2 that is highly conserved among betacoronaviruses. Although non-neutralizing, 54043-5 induced Fc-dependent antiviral responses in vitro , including antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP). In murine SARS-CoV-2 challenge studies, protection against disease was observed after introduction of Leu234Ala, Leu235Ala, and Pro329Gly (LALA-PG) substitutions in the Fc region of 54043-5. Together, these data provide new insights into the protective mechanisms of non-neutralizing antibodies and define a broadly conserved epitope within the S2 subunit. [Display omitted] • 50 cross-reactive coronavirus spike antibodies were isolated from human donors • 54043-5 binds spikes from multiple betacoronaviruses • Structural analysis of 54043-5 defines a conserved epitope at the apex of S2 • Fc attenuation confers neutralization-independent, protective phenotypes in mice Johnson et al. identify antibody 54043-5, a non-neutralizing antibody that broadly targets betacoronavirus spike proteins. 54043-5 targets a highly conserved epitope at the apex of the prefusion S2 subunit and elicits Fc-mediated immune functions. An Fc-knockout variant of 54043-5 protects mice from disease, suggesting additional considerations for developing antibody-based interventions. [ABSTRACT FROM AUTHOR]

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has shown wastewater (WW) surveillance to be an effective means of tracking the emergence of viral lineages which arrive by many routes of transmission including via transportation hubs. In the Canadian province of Ontario, numerous municipal wastewater treatment plants (WWTPs) participate in WW surveillance of infectious disease targets such as SARS-CoV-2 by qPCR and whole genome sequencing (WGS). The Greater Toronto Airports Authority (GTAA), operator of Toronto Pearson International Airport (Toronto Pearson), has been participating in WW surveillance since January 2022. As a major international airport in Canada and the largest national hub, this airport is an ideal location for tracking globally emerging SARS-CoV-2 variants of concern (VOCs). In this study, WW collected from Toronto Pearson's two terminals and pooled aircraft sewage was processed for WGS using a tiled-amplicon approach targeting the SARS-CoV-2 virus genome. Data generated was analyzed to monitor trends of SARS-CoV-2 lineage frequencies. Initial detections of emerging lineages were compared between Toronto Pearson WW samples, municipal WW samples collected from the surrounding regions, and Ontario clinical data as published by Public Health Ontario. Results enabled the early detection of VOCs and individual mutations emerging in Ontario. On average, the emergence of novel lineages at the airport preceded clinical detections by 1–4 weeks, and up to 16 weeks in one case. This project illustrates the efficacy of WW surveillance at transitory transportation hubs and sets an example that could be applied to other viruses as part of a pandemic preparedness strategy and to provide monitoring on a mass scale.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has posed extraordinary challenges to global health systems and economies. The virus's rapid evolution has resulted in several variants of concern (VOCs), including the highly transmissible Omicron variant, characterized by extensive mutations. In this study, we investigated the genetic diversity, population differentiation, and evolutionary dynamics of the Omicron VOC during the fifth wave of COVID-19 in Pakistan. Methods: A total of 954 Omicron genomes sequenced during the fifth wave of COVID-19 in Pakistan were analyzed. A Bayesian framework was employed for phylogenetic reconstructions, molecular dating, and population dynamics analysis. Results: Using a population genomics approach, we analyzed Pakistani Omicron samples, revealing low within-population genetic diversity and significant structural variation in the spike (S) protein. Phylogenetic analysis showed that the Omicron variant in Pakistan originated from two distinct lineages, BA.1 and BA.2, which were introduced from South Africa, Thailand, Spain, and Belgium. Omicron-specific mutations, including those in the receptor-binding domain, were identified. The estimated molecular evolutionary rate was 2.562E-3 mutations per site per year (95% HPD interval: 8.8067E-4 to 4.1462E-3). Bayesian skyline plot analysis indicated a significant population expansion at the end of 2021, coinciding with the global Omicron outbreak. Comparative analysis with other VOCs showed Omicron as a highly divergent, monophyletic group, suggesting a unique evolutionary pathway. Conclusions: This study provides a comprehensive overview of Omicron's genetic diversity, genomic epidemiology, and evolutionary dynamics in Pakistan, emphasizing the need for global collaboration in monitoring variants and enhancing pandemic preparedness.

The psychosocial health of children and adolescents has been particularly affected by the COVID-19 pandemic. Containment measures have restricted social development, education and recreational activities, may have increased family conflicts and, in many cases, led to feelings of loneliness, sleep disturbances, symptoms of anxiety and depression. We conducted a systematic review to identify interventions that seek to ameliorate these detrimental effects of the COVID-19 pandemic and to build resilience in children and adolescents. Literature searches were conducted in the databases MEDLINE, EMBASE, PsycINFO, CENTRAL, WHO COVID-19 Global literature on coronavirus disease and Cochrane COVID-19 Study Register (up to 30 June 2022). The searches retrieved 9557 records of which we included 13 randomized-controlled trials (RCTs) for evidence synthesis. Included studies predominantly implemented online group sessions for school-aged children with either a psychological component, a physical activity component, or a combination of both. A meta-analysis of seven studies on anxiety and five on depressive symptoms provided evidence for a positive effect of interventions by reducing anxiety (Standardized Mean Difference (SMD) (95% CI): − 0.33 (− 0.59; − 0.06)) and depressive symptoms (SMD (95% CI): − 0.26 (− 0.36; − 0.16)) compared to the control interventions. Studies also showed improvements in positive mental health outcomes, such as resilience (n = 2) and mental and psychological wellbeing (n = 2). Exploratory subgroup analyses suggested a greater effectiveness of interventions that (i) are of higher frequency and duration, (ii) enable personal interaction (face-to-face or virtually), and (iii) include a physical activity component. Almost all studies were judged to be at high risk of bias and showed considerable heterogeneity. Further research may focus on the contribution of different intervention components or distinct subgroups and settings, and should examine children and adolescents over longer follow-up periods.

Objective: We describe and analyze case investigation and contact tracing (CICT) efforts across Ohio's public universities in response to COVID-19 to distill challenges and lessons learned and suggest future opportunities for universities to mobilize in the face of emergent public health crises. Participants: Faculty, staff, and graduate students from Ohio's fourteen public universities. Methods: In-depth, semi-structured interviews were conducted with representatives from nine of the 14 universities; representatives from the remaining five universities completed a brief questionnaire. Interviews were transcribed in their entirety and thematically analyzed. Results: Emergent themes include the significance of local relationships for implementing locally tailored solutions; the presence of discrete challenges in doing CICT work with university and local communities, and the importance of university students in pandemic response. Conclusions: There are unique challenges associated with disease control across university populations and surrounding communities, but students from diverse academic background are a potential source of assistance.

Never in modern times has public health communication been so critical yet so fragile. When the first COVID-19 case was detected in Taiwan, Taiwanese health officials readily embedded pandemic detective narratives within public announcements to alert and reassure citizens about the government's preparedness. Such narratives are subject to revision because of challenges from the press, thereby inviting uncertainty as to who is telling the truth. In this study, I draw on the notions of narrative construction and circulation to analyze video recordings of daily press conferences about COVID-19 in Taiwan and trace how the Taiwanese media covered the island's first COVID-19 case from diagnosis to recovery. Along the way, pandemic detective narratives were multimodally told, untold, and retold. The health officials' narrative (re)entextualizations conflicted with those of the press and the person with COVID-19. This conflict stemmed from the different means of narrative construction and circulation that each narrator utilized to make sense of the illness experience. The differences suggest a tension between asserting control and conveying authenticity that intertextually potentiates and debilitates trust. [ABSTRACT FROM AUTHOR]

Why you should read this article: • To learn about a project that aimed to support teams caring for children and young people to reflect on their experiences and the effects of the coronavirus disease 2019 (COVID-19) pandemic • To recognise the need to ensure staff are adequately prepared to manage any future surges in respiratory illness effectively • To be aware of the potential long-term effects of the COVID-19 pandemic on emotional health and well-being. The coronavirus disease 2019 (COVID-19) pandemic was a challenging experience for children and young people’s services, and the workforce. The Valuing All Staff Together programme was a one-year project hosted by the North West Paediatric Critical Care, Surgery in Children, Long Term Ventilation Operational Delivery Network to support teams caring for children and young people to reflect on their experiences of the COVID-19 pandemic. Using an online survey, focus groups and interviews, it gave staff the opportunity to explore and understand the effects of the pandemic and the subsequent surge in demand, including how these affected services and the emotional health and well-being of staff. This would enable better preparation for future surges in respiratory illness in terms of learning, training and development. This article describes the programme’s aim, method and findings, and the main recommendations for practice. [ABSTRACT FROM AUTHOR]

Rift Valley fever virus, a pathogen to ruminants, camelids, and humans, is an emerging mosquito-borne bunyavirus currently endemic to Africa and the Arabian Peninsula. Although animals are primarily infected via mosquito bites, humans mainly become infected following contact with infected tissues or fluids of infected animals. There is an urgent need for adequate countermeasures, especially for humans, because effective therapeutics or vaccines are not yet available. Here we assessed the safety, tolerability, and immunogenicity of a next-generation, four-segmented, live-attenuated vaccine candidate, referred to as hRVFV-4s, in humans. A first-in-human, single-centre, randomised, double-blind, placebo-controlled trial was done in Belgium in which a single dose of hRVFV-4s was administered to healthy volunteers aged 18–45 years. Participants were randomly assigned using an interactive web response system. The study population encompassed 75 participants naive to Rift Valley fever virus infection, divided over three dosage groups (cohorts) of 25 participants each. All participants were followed up until 6 months. Using a staggered dose escalating approach, 20 individuals of each cohort were injected in the deltoid muscle of the non-dominant arm with either 104 (low dose), 105 (medium dose), or 106 (high dose) of 50% tissue culture infectious dose of hRVFV-4s as based on animal data, and five individuals per cohort received formulation buffer as a placebo. Primary outcome measures in the intention-to-treat population were adverse events and tolerability. Secondary outcome measures were vaccine-induced viraemia, vaccine virus shedding, Rift Valley fever virus nucleocapsid antibody responses (with ELISA), and neutralising antibody titres. Furthermore, exploratory objectives included the assessment of cellular immune responses by ELISpot. The trial was registered with the EU Clinical Trials Register, 2022-501460-17-00. Between August and December, 2022, all 75 participants were vaccinated. No serious adverse events or vaccine-related severe adverse events were reported. Pain at the injection site (51 [85%] of 60 participants) was most frequently reported as solicited local adverse event, and headache (28 [47%] of 60) and fatigue (28 [47%] of 60) as solicited systemic adverse events in the active group. No vaccine virus RNA was detected in any of the blood, saliva, urine, or semen samples. Rift Valley fever virus nucleocapsid antibody responses were detected in most participants who were vaccinated with hRVFV-4s (43 [72%] of 60 on day 14) irrespective of the administered dose. In contrast, a clear dose–response relationship was observed for neutralising antibodies on day 28 with four (20%) of 20 participants responding in the low-dose group, 13 (65%) of 20 responding in the medium-dose group, and all participants (20 [100%] of 20) responding in the high-dose group. Consistent with the antibody responses, cellular immune responses against the nucleocapsid protein were detected in all dose groups, whereas a more dose-dependent response was observed for the Gn and Gc surface glycoproteins. Neutralising antibody titres declined over time, whereas nucleocapsid antibody responses remained relatively stable for at least 6 months. The hRVFV-4s vaccine showed a high safety profile and excellent tolerability across all tested dose regimens, eliciting robust immune responses, particularly with the high-dose administration. The findings strongly support further clinical development of this candidate vaccine for human use.

In 2016, WHO designated Lassa fever a priority disease for epidemic preparedness as part of the WHO Blueprint for Action to Prevent Epidemics. One aspect of preparedness is to promote development of effective medical countermeasures (ie, diagnostics, therapeutics, and vaccines) against Lassa fever. Diagnostic testing for Lassa fever has important limitations and key advancements are needed to ensure rapid and accurate diagnosis. Additionally, the only treatment available for Lassa fever is ribavirin, but controversy exists regarding its effectiveness. Finally, no licensed vaccines are available for the prevention and control of Lassa fever. Ongoing epidemiological and behavioural studies are also crucial in providing actionable information for medical countermeasure development, use, and effectiveness in preventing and treating Lassa fever. This Personal View provides current research priorities for development of Lassa fever medical countermeasures based on literature published primarily in the last 5 years and consensus opinion of 20 subject matter experts with broad experience in public health or the development of diagnostics, therapeutics, and vaccines for Lassa fever. These priorities provide an important framework to ensure that Lassa fever medical countermeasures are developed and readily available for use in endemic and at-risk areas by the end of the decade.

Higher concentrations of ambient air pollutants, including PM2.5 and NO2, and other pollutants have been found near active oil and gas wells and may be associated with adverse COVID‐19 outcomes. We assessed whether residential exposure to nearby oil and gas production was associated with higher rates of the respiratory infection COVID‐19 and related mortality using a population‐based ecological study in California. Using gridded population estimates, we estimated area‐level exposure to annual average oil and gas production volume from active wells within 1 kilometer (km) of populated areas within census block groups from 2018 to 2020. We geocoded confirmed cases and associated deaths to assess block group case and mortality rates from COVID‐19 from February 2020 to January 2021. We fit hierarchical Poisson models with individual and area covariates (e.g., age, sex, socioeconomic disadvantage), and included time and other interactions to assess additional variation (e.g., testing, reporting rates). In the first 4 months of the study period (February–May 2020), block groups in the highest tertile of oil and gas production exposure had 34% higher case rates (IRR: 1.34 95% CI: 1.20, 1.49) and 55% higher mortality rates (MRR: 1.52 95%: CI: 1.14, 2.03) than those with no estimated production, after accounting for area‐level covariates. Over the entire study period, we observed moderately higher mortality rates in the highest group (MRR: 1.16 95%: CI: 1.01, 1.33) and null associations for case rates. Plain Language Summary: Exposure to air, noise, light pollution and other localized stressors from active oil and gas drilling may affect the immune and cardiovascular systems and respiratory health, including diseases such as COVID‐19. This study reports on COVID‐19 case and death rates in communities within 10 km of active oil and gas production. We observed that California communities that were located less than 1 km from an actively producing oil and gas well were more likely to have higher COVID‐19 case and death rates in the first 4 months of the pandemic, especially when the level of production was high. Across our entire study time (February 2020–January 2021), we did not observe higher rates of cases or deaths in these communities, except for deaths in communities with the highest amount of production. These results suggest that if there is an effect of oil and gas production on COVID‐19 rates, it may be on the number of people that become severely ill; overall, it suggests that more research may help to understand why different communities had different levels of COVID‐19. Key Points: Using gridded population estimates, we estimated exposure to oil and gas production in areas within 1 km of an active wellWe observed higher reported case and mortality rates in areas with higher estimated oil and gas production from February to May 2020We geocoded COVID‐19 cases and deaths to census block groups and estimated age and sex‐specific mortality rates from February 2020 to January 2021 [ABSTRACT FROM AUTHOR]

The 2023–2024 influenza epidemic saw the return of typical late-season influenza B circulation. The epidemic was declared in week 45 (week ending November 11, 2023) due to the predominant circulation of influenza A(H1N1) and peaked in week 52 (week ending December 30, 2023); however, as influenza A circulation decreased, influenza B detections and the percentage of tests positive increased, reaching its peak in week 14 (week ending April 6, 2024). Influenza B/Victoria dominated this wave of activity, contributing to the ongoing discussion about the apparent disappearance of influenza B/Yamagata. With the recommendation for the removal of influenza B/Yamagata lineages from the recommended seasonal influenza vaccine components, the influenza surveillance community is preparing for the possibility of a new seasonal pattern dominated by influenza B/Victoria circulation. This season, as a result of influenza B/Victoria’s overwhelming predominance, younger age groups were primarily affected by the wave of influenza B activity. Over the course of the season, among all influenza B detections, 52% occurred in children aged 0–19 years. Among all influenza B-associated hospitalizations, 46.4% were in children aged 0–19 years, and the highest cumulative hospitalization rates for influenza B were among children younger than five years (n=37 per 100,000 population) and children between the ages of 5–19 years (n=15 per 100,000 population). Continued vigilance and surveillance around influenza B trends and epidemiology is required to contribute to effective epidemic preparedness. [ABSTRACT FROM AUTHOR]

Background: In the COVID-19 pandemic, novel regional services and communication channels emerged across all sectors of the German healthcare system. To contribute to pandemic preparedness, this study aims to describe newly established services in response to the COVID-19 pandemic from a stakeholder perspective and to examine the interprofessional communication channels, applying a nationwide cross-sectional approach. Methods: A nationwide sample of German healthcare stakeholders comprising general practitioners, associations of statutory health insurance physicians, hospital medical directors, local health departments, rescue coordination centres, medical directors of emergency services, outpatient nursing services, nursing homes, community care access centres, and hospital nursing managers was surveyed. A web-based questionnaire asked for their level of participation in newly implemented regional COVID-19 services and communication channels. Stakeholders' level of recommendation was measured using the Net Promotor Score (NPS), a metric that assesses their satisfaction towards the services surveyed. Results: In total, 1312 healthcare stakeholders participated in the survey. Diagnostic centres (23.0–90.9%), COVID-19 wards in hospitals (40.5–92.1%), emergency medical vehicles designated solely for COVID-19 patients (16.5–68.4%), and crisis intervention teams (11.6–30.6%) exhibited the highest rates of engagement. The services receiving the highest recommendation for future use were COVID-19 focus practices (NPS: 33.4–43.7), COVID-19 wards in hospitals (NPS: 47.6–84.4), transportation of COVID-19 patients exclusively by predefined professional groups (NPS: 12.5–36.4), and newly implemented digitally supported nursing services (NPS: 58.3–100.0). Telephones emerged as the most frequently used communication channel (58.0–96.7%), while email was the primary digital channel (23.7–81.5%). Conclusions: During the COVID-19 pandemic, Germany experienced significant variation in the implementation of pandemic-related services across healthcare sectors, with stakeholders prioritising services built on existing healthcare structures. Developing a proactive digital infrastructure to connect healthcare professionals from different sectors is crucial for better future pandemic management. [ABSTRACT FROM AUTHOR]

The adenovirus detection rate is <10% throughout the year in South Korea; however, during the summer of 2023, it showed an unusual increase. We analyzed the adenovirus detection rate using data from the Korea Respiratory Integrated Surveillance System before and after coronavirus disease (COVID-19) collected from 2019 to week 36 of 2023. Before the COVID-19 outbreak in 2019, the mean detection rate was 8.2%, which decreased to 6.1% during the COVID-19 pandemic from 2020 to 2022. In 2023, the mean detection rate was 14.3% in week 36 and the highest in week 34, at 42.2%, and adenovirus was predominantly detected in the summer. The detection rate by age group showed substantially high activity among 0–12-yr-olds after the pandemic. This age group had a steady mean rate of 9.5% during the pandemic, without seasonality. In 2023, the detection rate surged in the 0–6-yr and 7–12-yr age groups, peaking at 61.6% and 57.1%, respectively. The dominant epidemic serotypes were HAdV-1 and HAdV-2 during and HAdV-3 after the pandemic. The multifaceted non-pharmaceutical interventions during the COVID-19 pandemic considerably impacted the prevalence of common respiratory viruses and complicated respiratory virus patterns after the pandemic. Constant surveillance is crucial for epidemic preparedness to monitor the possible surge of certain respiratory viruses. [ABSTRACT FROM AUTHOR]

Background: A review of key learnings from the response to the COVID-19 pandemic in nursing homes in Ireland can inform planning for future pandemics. This study describes barriers and facilitators contributing to COVID-19 outbreak management from the perspective of frontline teams. Methods: A qualitative study involving ten online focus group meetings was conducted. Data was collected between April and June 2023. The focus group discussions explored the views, perceptions and experiences of COVID-19 Response Team (CRT) members, clinical/public health experts who worked with them, and care professionals who worked in frontline managerial roles during the pandemic. All nine Community Healthcare Organisations and six Public Health Areas in Ireland were represented. Inductive reflexive thematic analysis was carried out using NVivo Pro 20. Results: In total, 54 staff members participated in focus group meetings. Five themes were developed from a thematic analysis that covered topics related to (1) infection prevention and control challenges and response to the pandemic, (2) social model of care and the built environment of nursing homes, (3) nursing home staffing, (4) leadership and staff practices, and (5) support and guidance received during the pandemic. Conclusions: The response to the COVID-19 pandemic has resulted in a steep learning curve, internationally and in Ireland. Preparing better for future pandemics not only requires changes to infection control and outbreak response but also to the organisation and operation of nursing homes. There is a great need to strengthen the long-term care sector's regulations and support around staffing levels, nursing home facilities, governance, use of technology, infection prevention and control, contingency planning, and maintaining collaborative relationships and strategic leadership. Key findings and recommendations from the Irish example can be used to improve the quality of care and service delivery at local, national, and policy levels and improve preparedness for future pandemics, in Ireland and internationally.

Background: The unprecedented COVID-19 pandemic has become an endemic disease of global public health importance. Mass COVID-19 vaccination has been an essential global control strategy amidst challenges of limited acceptance. Because of globalization, COVID-19/similar diseases vaccination acceptance and the determinants in any particular setting are important global public health issues. Using a novel and pragmatic framework, this study explored determinants of COVID-19 vaccination acceptance among community members during the pandemic in Ebonyi state, Nigeria, and made policy-relevant recommendations on how to increase vaccination acceptance in subsequent outbreaks/pandemics. Methods: This qualitative study was based on the novel and pragmatic Individual Experiences and Perceptions and Complacency, Confidence, Convenience, and Compulsion (Four 'Cis') Determinants of Vaccination Acceptance Conceptual Framework – Omale INDEPT FORCIS Framework. On April 26 and 27, 2022, 20 semi-structured face-to-face focus group discussions were conducted in local language and pidgin English with 100 purposively selected consenting/assenting community members aged 15 years and above who had resided in the community for at least one year. Data was analysed using deductive (with some inductive) thematic analytic approach. Results: The many, diverse, and significant determinants of COVID-19 vaccination acceptance found were factors that were individual-related (individual experiences and perceptions and knowledge about COVID-19, COVID-19 vaccine/vaccination, and the vaccination process/system, sociodemographic, individual's condition (e.g. pregnancy)); COVID-19-related (factuality, transmissibility, frequency, severity, fatality); COVID-19 vaccine/vaccination-related (safety/side-effects, effectiveness, speedy production); COVID-19 vaccination process/system-related (real availability/accessibility); family, group, and other individual-related (experiences and perceptions and actions); and broader local, national, international, and global (LONING) context-related (socio-political, economic, historic, health system factors). The broader LONING contextual factors included the unprecedented disinformation/conspiracy theories, non-sustained COVID-19 risk/behaviour change communication, enforcement and non-enforcement or termination of peculiar control policies/measures (lockdowns, social/physical distancing, use of face mask etc.), mandatory COVID-19 vaccination policies, provision of incentives, past experiences regarding the Ebola viral disease outbreak, (un)trustworthiness of the Nigerian health system and her international/global partners, and the (un)trustworthiness of the governments in Nigeria and bad/good governance, inclusive of the failure of the Ebonyi state government to distribute the COVID-19 palliatives to the people during the lockdowns. Conclusion: The evidence illuminates complex and interrelated, specific underlying, and peculiar policy-relevant LONING determinants of COVID-19 vaccination acceptance and emphasizes the need for concerted and comprehensive LONING strategies (involving all the relevant LONING stakeholders/policy makers) in addressing these determinants to increase vaccination acceptance among community members in subsequent outbreaks/pandemics in Ebonyi state/Nigeria and similar settings.

The recurring spillover of pathogenic coronaviruses and demonstrated capacity of sarbecoviruses, such SARS-CoV-2, to rapidly evolve in humans underscores the need to better understand immune responses to this virus family. For this purpose, we characterized the functional breadth and potency of antibodies targeting the receptor binding domain (RBD) of the spike glycoprotein that exhibited cross-reactivity against SARS-CoV-2 variants, SARS-CoV-1 and sarbecoviruses from diverse clades and animal origins with spillover potential. One neutralizing antibody, C68.61, showed remarkable neutralization breadth against both SARS-CoV-2 variants and viruses from different sarbecovirus clades. C68.61, which targets a conserved RBD class 5 epitope, did not select for escape variants of SARS-CoV-2 or SARS-CoV-1 in culture nor have predicted escape variants among circulating SARS-CoV-2 strains, suggesting this epitope is functionally constrained. We identified 11 additional SARS-CoV-2/SARS-CoV-1 cross-reactive antibodies that target the more sequence conserved class 4 and class 5 epitopes within RBD that show activity against a subset of diverse sarbecoviruses with one antibody binding every single sarbecovirus RBD tested. A subset of these antibodies exhibited Fc-mediated effector functions as potent as antibodies that impact infection outcome in animal models. Thus, our study identified antibodies targeting conserved regions across SARS-CoV-2 variants and sarbecoviruses that may serve as therapeutics for pandemic preparedness as well as blueprints for the design of immunogens capable of eliciting cross-neutralizing responses. Author summary: There is a large collection of sarbecoviruses related to SARS-CoV-2 circulating in animal reservoirs with the potential to spillover into humans. Neutralizing antibodies have the potential to protect against infection, although viral escape is common. In this study, we isolated several monoclonal antibodies that show broad activity against different sarbecoviruses. The antibodies target epitopes in the core of the receptor binding domain that are highly conserved in sequence across sarbecoviruses and emerging SARS-CoV-2 variants. One antibody showed remarkable breadth against both SARS-CoV-1 variants as well as diverse sarbecoviruses. The results of deep mutational scanning suggest that mutations at these predicted sites of escape may functionally constrain viral fitness. Our functional profiling of cross-reactive antibodies highlights vulnerable sites of sarbecoviruses, with some antibodies poised as broadly neutralizing candidates for therapeutic use against future sarbecovirus emergence.

The emergence of hitherto unknown viral pathogens presents a great challenge for researchers to develop effective therapeutics and vaccines within a short time to avoid an uncontrolled global spread, as seen during the coronavirus disease 2019 (COVID-19) pandemic. Therefore, rapid and simple methods to identify immunogenic antigens as potential therapeutical targets are urgently needed for a better pandemic preparedness. To address this problem, we chose the well-characterized Modified Vaccinia virus Ankara (MVA)-T7pol expression system to establish a workflow to identify immunogens when a new pathogen emerges, generate candidate vaccines, and test their immunogenicity in an animal model. By using this system, we detected severe acute respiratory syndrome (SARS) coronavirus 2 (SARS-CoV-2) nucleoprotein (N)-, and spike (S)-specific antibodies in COVID-19 patient sera, which is in line with the current literature and our observations from previous immunogenicity studies. Furthermore, we detected antibodies directed against the SARS-CoV-2-membrane (M) and -ORF3a proteins in COVID-19 patient sera and aimed to generate recombinant MVA candidate vaccines expressing either the M or ORF3a protein. When testing our candidate vaccines in a prime-boost immunization regimen in humanized HLA-A2.1-/HLA-DR1-transgenic H-2 class I-/class II-knockout mice, we were able to demonstrate M- and ORF3a-specific cellular and humoral immune responses. Hence, the established workflow using the MVA-T7pol expression system represents a rapid and efficient tool to identify potential immunogenic antigens and provides a basis for future development of candidate vaccines.

AbstractObjectiveDesignResultsConclusionThis study explored children’s post-pandemic articulations regarding the coronavirus along with their lived experiences during the COVID-19 pandemic.A qualitative survey featuring drawings, comments, questions and follow-up interviews was employed to gather data from 108 infected children aged 13 to 14 from two middle schools in China. This multimodal approach allowed for a rich capture of the children’s articulations of their pandemic experiences.Children’s multimodal articulations conveyed not only the biological features of, but also their emotional reactions to the coronavirus. The pandemic had disrupted children’s lives, making online learning, sleep and screen engagement dominant in their daily routines, while also compounding children’s unhappiness primarily due to restrictions on social interactions. Children associated the coronavirus with biological, medical, psychological and social aspects. Increased sanitisation and hygiene habits featured their pre‐to-post pandemic changes. Furthermore, children exhibited an awareness regarding preventive measures and transmission modes, albeit with certain biases or gaps. Their misunderstandings about recuperative strategies merit clarification.The COVID-19 pandemic has had profound and multifaceted impacts on children’s emotional well-being, daily routines, social interactions, education, and health-related behaviors. Children’s multimodal articulations revealed a spectrum of adverse effects caused by the pandemic, calling for targeted health interventions to mitigate these negative effects while also equipping children with resilience and coping skills for navigating future health crises. Incorporating children’s perspectives and experiences into future pandemic preparedness and health promotion strategies is essential for addressing their vulnerabilities and ensuring their overall well-being during public health crises.

The G20 summit is a unique opportunity for India to reinvigorate and realign its public health policies and enhance its role and influence in global health governance. India, as the world's most populous country and the fifth largest economy, has a vital stake and responsibility in addressing the health challenges and opportunities globally. The COVID-19 pandemic has exposed the vulnerabilities and interdependencies of the global health system and highlighted the need for stronger cooperation and solidarity among countries. The G20 summit provides a platform for India to showcase its public health achievements, such as its remarkable vaccination drive, its universal health coverage scheme, its digital health initiatives, and its leadership in health diplomacy and research. It enables India to seek cooperation and support from other countries on health issues of common concern, such as ensuring equitable access to vaccines and therapeutics, strengthening health systems resilience and preparedness, promoting health innovation and research, and fostering health diplomacy and leadership. At the G20 summit, India recommends to take concrete actions such as advocating for a global treaty on pandemic preparedness, supporting a global health financing mechanism, enhancing W.H.O.'s role, and strengthening the G20's health agenda and governance. Key Messages: This article provides a comprehensive and timely analysis of India's public health situation and priorities in the context of the G20 summit and offers practical and strategic advice for India's engagement and influence at the global health stage. It argues that the G20 summit is a critical platform for India to showcase its public health achievements and aspirations and to seek cooperation and support from other countries on health issues of common concern, such as the COVID-19 pandemic, universal health coverage agenda, health workforce crisis and digital health revolution. It also suggests some concrete actions and recommendations for India to take at the G20 summit, such as advocating for equitable access to vaccines and therapeutics, strengthening health systems resilience and preparedness, promoting health innovation and research, and fostering health diplomacy and leadership. This article can help inform and inspire policymakers, practitioners, researchers and advocates who are interested in India's public health development and its role in global health governance. It can also stimulate further dialogue and debate on how India can leverage the G20 summit to advance its public health goals and collaborate with global partners on health challenges.

Objective: To describe the adoption of international travel measures during the first year of the COVID-19 pandemic. Methods: To comprehensively analyze the measures adopted, we constructed a dataset based on the WHO's Public Health and Social Measures (PHSM) database, which covered 252 countries, territories, or other areas (CTAs), including all 194 WHO Member States, from December 31, 2019, to December 31, 2020. We examined the adoption of measures by type, over time, and by the implementing and targeted CTA, including their levels of income. Findings: We identified 11,431 international travel measures implemented during the first year of the pandemic. The adoption of measures was rapid and widespread: over 60% of Member States had adopted a travel measure before the WHO declared COVID-19 a Public Health Emergency of International Concern on January 30, 2020. Initially, health screening and travel restrictions were the most adopted measures; however, quarantine and testing became more widely adopted over time. Although only a small portion of the total measures adopted constituted full border closure, approximately half of all Member States implemented this measure. Many travel measures targeted all CTAs but were unlikely to have been adopted universally enough to provide public health benefits. Low-income countries relied more on more universal measures, including full border closure, and were slower in scaling up testing compared to higher-income countries. Conclusion: The adoption of international travel measures during the first year of the COVID-19 pandemic varied across jurisdictions and over time. Lower-income countries used a different mix and scaled-up measures slower than higher-income countries. Understanding what measures were used is crucial for assessing their effectiveness in controlling the spread of COVID-19, reviewing the usefulness of the International Health Regulations, and informing future pandemic preparedness and response activities.

Background: The level of trust in health systems is often in flux during public health emergencies and presents challenges in providing adequate health services and preventing the spread of disease. Experiences during previous epidemics has shown that lack of trust can impact the continuity of essential health services and response efforts. Guinea and Sierra Leone were greatly challenged by a lack of trust in the system during the Ebola epidemic. We thus sought to investigate what was perceived to influence public and community trust in the health system during the COVID-19 pandemic, and what strategies were employed by national level stakeholders in order to maintain or restore trust in the health system in Guinea and Sierra Leone. Methods: This qualitative study was conducted through a document review and key informant interviews with actors involved in COVID-19 and/or in malaria control efforts in Guinea and Sierra Leone. Key informants were selected based on their role and level of engagement in the national level response. Thirty Six semi-structured interviews (16 in Guinea, 20 in Sierra Leone) were recorded, transcribed, and analyzed using an inductive and deductive framework approach to thematic analysis. Results: Key informants described three overarching themes related to changes in trust and health seeking behavior due to COVID-19: (1) reignited fear and uncertainty among the population, (2) adaptations to sensitization and community engagement efforts, and (3) building on the legacy of Ebola as a continuous process. Communication, community engagement, and on-going support to health workers were reiterated as crucial factors for maintaining trust in the health system. Conclusion: Lessons from the Ebola epidemic enabled response actors to consider maintaining and rebuilding trust as a core aim of the pandemic response which helped to ensure continuity of care and mitigate secondary impacts of the pandemic. Monitoring and maintaining trust in health systems is a key consideration for health systems resilience during public health emergencies. [ABSTRACT FROM AUTHOR]

The primary claim of this essay is that historical fluency is required for effective work in crafting legal and policy interventions as a part of public health emergency preparedness and response (PHEPR). At a broad level, public health law is explicitly recognized as a key systems-level component of PHEPR practice. 1 This essay therefore focuses on the extent to which historical fluency is necessary or at least useful to all aspects of PHEPR that draw on or deploy legal and policy mechanisms (e.g. design, planning, implementation, dissemination, monitoring and evaluation, etc.). The essay collectively refers to these legal and policy mechanisms as epidemic law and policy response (ELAPR). Part I explains the concept of historical fluency. Part II explores the foundations of public health law both as a way of highlighting key structural features of ELAPR and in supporting the claim that historical fluency is critical for ELAPR. Part III applies the previous arguments to a specific case study to highlight the promise and power of historical fluency – the outbreak of bubonic plague in San Francisco in 1900. Tracking this essay's pragmatic focus, part IV offers several recommendations for how specifically historical fluency in public health law and ethics can be operationalized in PHEPR practice and policy. Part V summarizes and concludes. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic created critical challenges for hospitals and health care providers. Suddenly clinics were forced to close; elective procedures were delayed; scheduled visits were canceled; emergency rooms were overcrowded; hospital beds, equipment, and personal protective equipment (PPE) were in short supply; and staff were faced with rapidly changing circumstances, care protocols, trauma, and personal risk. To better address challenges of the ongoing COVID-19 pandemic and prepare for future pandemics, the National Telemedicine Technology Assessment Resource Center (TTAC) was asked to develop a Pandemic Response Action Plan that would allow its users to address critical issues with available telemedicine and related technologies. The project was constructed in 3 phases. Phase 1-Develop a Pandemic Response Action Plan and a Pandemic Response Action Plan Policy and Regulatory Summary, which identifies the regulatory challenges as well as policy recommendations. Phase 2-Publish the Action Plan and the Policy and Regulatory Summary. Phase 3-Look at health care providers who used the approaches, tools, and technology in the Pandemic Action Plan and document the results. This document represents Phase 3. This document is Phase 3. In this report we look back at health care providers who used the approaches in the Phase 1 Pandemic Response Action Plan as published in Phase 2. In this document we report on the challenges and results of implementing parts of the Pandemic Action Plan. It records the findings, conclusions, and recommendations resulting from the experience of health care providers and the professional experiences of the team and their organizations in implementing parts or all of the plan. Methods: The same multidisciplinary team that constructed Phase 1 and Phase 2 were engaged to develop this Phase 3 report. The members of the team represent leadership expertise and key stakeholders in health care delivery during a pandemic (administration, infection control, physicians, nurses, public health, contingency planning, disaster response, and information technology) as well as a facilitator. For Phase 3, the group used structured brainstorming to define the findings, issues, and results of their own organizations' digital health response to the pandemic. In addition, eight health care providers (hospitals) identified by the Telemedicine Resource Centers' (TRCs) organizations, who used the Pandemic response Plan (created in Phases 1 and 2), were interviewed. All interviews were conducted by the same facilitator with leaders (CEO, and leaders of the telemedicine programs) in each of the eight programs, using a standard questionnaire created by the team. Current literature references are included in this report to illustrate when findings are known to have broader applicability. Conclusions: The impact of the COVID-19 Pandemic was severe and identified multiple critical challenges and weaknesses. Applying the approaches, tools, and technology outlined in the Pandemic Response Action Plan proved to be effective in addressing critical provider challenges. However, implementing these tools during a crisis was difficult unless the organization had experience with the tools and necessary workflows in advance. Implementing these tools as part of standard workflows and everyday operations increased the capabilities and resilience of these organizations in the provision of care during this and for future pandemics.

This article explores the significance of trust in public health response efforts, specifically in relation to the COVID-19 pandemic. Trust in authorities and institutions is crucial for promoting compliance with health protocols and behaviors. Various factors, such as information sources, media credibility, and personal experiences, influence trust. The article focuses on the New York City Test and Trace program and identifies both facilitators and barriers to trust, including the involvement of reputable organizations, adapting to community needs, and forming partnerships. The findings emphasize the importance of trust in public health initiatives and offer insights for enhancing trustworthiness. The article also discusses the implementation of the Test & Trace (T2) program in New York City during the COVID-19 pandemic. The program established partnerships with community-based organizations (CBOs) and community advisory boards (CABs) that had existing relationships with the Department of Health and Mental Hygiene (DOHMH). Trusted sources of information, such as local media outlets, were utilized to effectively communicate COVID-19 information and resources. Hiring frontline staff from local communities who shared similar demographics and identities with community members helped to foster trust. However, barriers to trust included historical mistrust in government and the medical establishment, inconsistent messaging, and misinformation. Recommendations for enhancing trust in public health responses include building relationships with trusted organizations, conducting early media campaigns, and actively addressing misinformation.

South African research ethics committees (RECs) faced significant challenges during the COVID-19 pandemic. Research ethics committees needed to find a balance between careful consideration of scientific validity and ethical merit of protocols, and review with the urgency normally associated with public health emergency research. We aimed to explore the views of South African RECs on their pandemic preparedness and response during COVID-19. We conducted in-depth interviews with 21 participants from RECs that were actively involved in the review of COVID-19 related research, at seven academic institutions across South Africa. Interviews were conducted remotely using an in-depth interview guide that included questions regarding REC preparedness and response to COVID-19. Interviews were conducted until data saturation, and audio-recordings were transcribed verbatim and coded. An inductive approach to thematic analysis was used to organise data into themes and sub-themes. This study focused on three main themes: coping during COVID-19, building REC capacity during pandemic times and a consistently cautious approach to mutual recognition of REC reviews. Despite an initial sense of unpreparedness, RECs were able to adapt and maintain careful ethical oversight of both COVID and non-COVID research, and the rigour of REC reviews. Several important lessons for preparedness and response to future pandemics were identified, including heightened awareness of publication, funding and political pressures, the importance of regular training for RECs and researchers, and strategies to enhance moral resilience of REC members. Incremental steps are needed to build trust and authentic partnerships among RECs in inter-pandemic times, to facilitate collaboration during future public health emergencies. [ABSTRACT FROM AUTHOR]

Responses to the COVID-19 pandemic globally disrupted lives and contributed to the exacerbation of pre-existing inequalities. Women in research were also affected. The prominent role that women played in professional and personal care duties had a detrimental effect on their research outputs, potentially hindering their career progression. Moreover, the challenges faced by women academics during the pandemic, including job loss, increased mental health issues, and the intersection of gender with other socio-demographic traits exacerbated existing gender disparities within academia. By systematically scoping the qualitative literature on the experiences of women researchers during the pandemic, this study sought to explore how women experienced and reacted to the challenges generated by the COVID-19 pandemic. A qualitative meta synthesis of the included studies revealed three themes: gendered professional expectations, colliding identities and coping strategies. These themes show how gendered roles such as teaching and professional care work, associated with the hierarchical and gendered division of tasks both at home and in the workplace, made women feel unsupported and alienated as relevant agents in the academic context. The study reveals the importance of pastoral care, teaching and service work as the essential backbone of the academic infrastructure, especially in times of crises. It also exposes how productivity-focused researcher assessment criteria, rewarding mainly individual results and unrewarding of care and service work, can be viewed as perpetuating structural inequalities based on gender, parenting situations, contractual situations and background. In conclusion, this study exposes the need to proactively address the gendered practices and implicit biases which reproduce inequalities within academia and highlights how paying attention to the experiences and needs of women researchers is essential for improving the resilience and crises preparedness of academic the system.

In this case study we describe how Sydney Local Health District (SLHD) Disability Inclusion and Advice Service (DIAS) provided support to disability group homes during the COVID-19 Delta and Omicron waves. The study provides insights into group home providers' experience of supports implemented by SLHD and other stakeholders. A mixed method approach was undertaken that included analysing data from a database and electronic medical records and a survey of disability group home managers. DIAS developed a range of processes to support prevention, outbreak preparedness and response. This included developing a Disability Shared Living COVID-19 Pathway, engaging with group home providers through a fortnightly Community of Practice, assisting with improving vaccination status and procuring personal protective equipment. During an outbreak DIAS provided a 24 h, 7 days per week on call support, coordinated outbreak management team meetings and collaborated with several internal and external stakeholders. SLHD infection prevention and control nurses were recruited to undertake a process of reviewing outbreak management plans and providing support during an outbreak. Most disability providers (86%) reported that they felt very prepared to manage outbreaks at the time of the survey (August 2022) compared with the pre-Delta wave, for which 36% reported feeling 'not prepared'. The proportion who rated the support from the stakeholders as very supportive/supportive was as follows: SLHD (100%), NSW Health (64%), National Disability Insurance Agency (50%) and National Disability Insurance Scheme Quality & Safeguards Commission (37%). Our case study provides insights into the support that LHDs can provide to disability homes in response to future outbreaks. What is known about the topic? People with a disability (PWD) are at higher risk of morbidity and mortality following COVID-19 infection but little is known about how PWD were supported during the COVID-19 pandemic. What does this paper add? Describes one local health district (LHD's) approach to prevent, manage and minimise COVID-19 outbreaks in disability group homes along with insights from the disability group home managers on their experience of support provided by the LHD and other stakeholders. What are the implications for practitioners? Awareness of effective strategies supporting PWD that could be replicated in health organisations. [ABSTRACT FROM AUTHOR]

This study sheds light on the problems and strengths of disabled people during the ongoing COVID pandemic, as many societies are dropping mitigation measures. Fourteen disabled women from the United States participated in virtual focus groups, and the study identified five major themes: New Challenges, Old Challenges Persist, Structural Changes to Accessibility, Coping Resources, and Learning for Future. The findings aligned with existing literature on challenges related to vaccination, mask mandates, messages regarding value of disabled lives, and the need for disabled individuals to be involved in preparedness. By taking these findings into account, policymakers have an opportunity to create a society that prioritizes justice for disabled people, even during times of crisis. Points of interest: The findings explain the continued challenges faced by disabled women during the prolonged COVID-19 pandemic. A previously marginalized group, disabled women continue to be disproportionately impacted by the pandemic, with an increase in accessibility barriers and a surge in mental health symptoms as frequently mentioned challenges. The pandemic reinforced pre-existing stereotypes and prejudices, including the messages on the value of disabled lives in popular media. The participants highlighted improved accessibility in some areas, including proliferation of remote work, curbside pickup and delivery, and telehealth, and they expressed hope that those changes will become the norm for life in the post-pandemic world. Participants stressed the need for universal design and recommended the inclusion of disabled people in every stage of pandemic and crisis planning to make information, services, education, and work accessible for all.

Context: Since COVID-19, the European Commission (EC) has sought to expand its activities in health through the development of a European Health Union and within it the Health Emergencies Preparedness and Response Authority (HERA). Methods: The authors applied a discourse analysis to documents establishing HERA to investigate how the EC legitimated the creation of this institution. They focused on how it framed health emergencies, how it framed the added value of HERA, and how it linked HERA to existing EU activities and priorities. Findings: Their analysis demonstrates that security-based logics have been central to the EC's legitimation of HERA in alignment with a "securitization of health" occurring worldwide in recent decades. This legitimation can be understood as part of the EC's effort to promote future integration in health in the absence of new competences. Conclusions: Securitization has helped the EC raise its profile in health politically without additional competences, thereby laying the groundwork for potential future integration. Looking at the discursive legitimation of HERA sheds light not only on whether the EC is expanding its health powers but also how it strategizes to do so. HERA, while constrained, allows the EC to further deepen security-driven integration in health. [ABSTRACT FROM AUTHOR]

The World Health Organization's declaration of mpox (formerly known as monkeypox) as a public health emergency of international concern (PHEIC) in July 2022, followed by its resurgence in 2024, has sparked concerns about its potential impact on sports, especially contact sports such as football. Although mpox is not a pandemic (as of late September 2024), the coronavirus disease 2019 (COVID-19) experience offers valuable lessons for proactive planning in sports. Our conceptual framework has been designed to draw insightful lessons from the COVID-19 pandemic to assist sports organizations in planning for and preventing similar situations. We aimed to draw lessons from COVID-19 to help sports organizations enhance practical preparedness through effective planning and mitigation strategies. Accordingly, we sought to assess the potential impact of mpox on sports, with a focus on football (soccer), and to develop strategies for prevention, management, and preparedness based on epidemiological insights and lessons from COVID-19 pandemic experience. Here we review mpox's pathophysiology and possibility of transmission in sports settings and discuss tailored strategies, including risk assessments, testing protocols, hygiene measures, and return-to-play policies. This review highlights key differences between mpox and COVID-19 in transmission, incubation, and management, emphasizing the need for customized prevention and control measures in sports. We propose innovative risk assessment methods using global positioning system tracking and machine learning for contact analysis, alongside tailored testing and hygiene protocols. We emphasize the importance of proactive planning, noting improved preparedness in the sports community compared to the early days of COVID-19. In conclusion, our proposed framework provides sports organizations with practical tools to manage potential risks associated with mpox, ensuring the continuity of activities while prioritizing public health.

During various stages of the COVID‐19 pandemic, countries implemented diverse vaccine management approaches, influenced by variations in infrastructure and socio‐economic conditions. This article provides a comprehensive overview of optimization models developed by the research community throughout the COVID‐19 era, aimed at enhancing vaccine distribution and establishing a standardized framework for future pandemic preparedness. These models address critical issues such as site selection, inventory management, allocation strategies, distribution logistics, and route optimization encountered during the COVID‐19 crisis. A unified framework is employed to describe the models, emphasizing their integration with epidemiological models to facilitate a holistic understanding. This article also summarizes evolving nature of literature, relevant research gaps, and authors' perspectives for model selection. Finally, future research scopes are detailed both in the context of modeling and solutions approaches. [ABSTRACT FROM AUTHOR]

Vaccination in pregnancy is important to protect the mother and fetus from infectious diseases. The transfer of maternal antibodies across the placenta during pregnancy can continue to protect the neonate for several months after birth while the neonatal adaptive immune system develops. Several pathogens have been shown to impair the transplacental transfer of maternal antibodies, including human immunodeficiency virus, malaria, the severe acute respiratory syndrome coronavirus 2, and cytomegalovirus. This review discusses the mechanisms contributing to decreased transplacental antibody transfer in the setting of maternal infections, such as changes in antibody glycosylation profile, maternal hypergammaglobulinemia, and placental injury. The frequency of epidemics is increasing, and pregnant people are more likely to become exposed to novel pathogens now than they were in the past. Understanding the mechanisms by which infectious diseases impair maternal–fetal antibody transfer is important for pandemic preparedness to maximize the impact of maternal vaccination for child health.

The global COVID-19 pandemic has imposed unprecedented pressure on health systems and has interrupted public health efforts for other major health conditions, including HIV. It is critical to comprehensively understand how the pandemic has affected the delivery and utilization of HIV-related services and what are the effective strategies that may mitigate the negative impacts of COVID-19 and resultant interruptions. The current study thus aims to comprehensively investigate HIV service interruptions during the pandemic following a socioecological model, to assess their impacts on various outcomes of the HIV prevention and treatment cascade and to identify resilience resources for buffering impacts of interruptions on HIV treatment cascade outcomes. We will assess HIV service interruptions in South Carolina (SC) since 2020 using operational report data from Ryan White HIV clinics and HIV service utilization data (including telehealth use) based on statewide electronic health records (EHR) and cellphone-based place visitation data. We will further explore how HIV service interruptions affect HIV prevention and treatment cascade outcomes at appropriate geospatial units based on the integration of multi-type, multi-source datasets (e.g., EHR, geospatial data). Finally, we will identify institutional-, community-, and structural-level factors (e.g., resilience resources) that may mitigate the adverse impacts of HIV service interruptions based on the triangulation of quantitative (i.e., EHR data, geospatial data, online survey data) and qualitative (i.e., in-depth interviews with clinic leaders, healthcare providers, people living with HIV, and HIV clinic operational reports) data regarding health system infrastructure, social capital, and organizational preparedness. Our proposed research can lead to a better understanding of complicated HIV service interruptions in SC and resilience factors that can mitigate the negative effects of such interruptions on various HIV treatment cascade outcomes. The multilevel resilience resources identified through data triangulation will assist SC health departments and communities in developing strategic plans in response to this evolving pandemic and other future public health emergencies (e.g., monkeypox, disasters caused by climate change). The research findings can also inform public health policymaking and the practices of other Deep South states with similar sociocultural contexts in developing resilient healthcare systems and communities and advancing epidemic preparedness.

Background: The COVID-19 pandemic underlined the need for pandemic planning but also brought into focus the use of mathematical modelling to support public health decisions. The types of models needed (compartment, agent-based, importation) are described. Best practices regarding biological realism (including the need for multidisciplinary expert advisors to modellers), model complexity, consideration of uncertainty and communications to decisionmakers and the public are outlined. Methods: A narrative review was developed from the experiences of COVID-19 by members of the Public Health Agency of Canada External Modelling Network for Infectious Diseases (PHAC EMN-ID), a national community of practice on mathematical modelling of infectious diseases for public health. Results: Modelling can best support pandemic preparedness in two ways: 1) by modelling to support decisions on resource needs for likely future pandemics by estimating numbers of infections, hospitalized cases and cases needing intensive care, associated with epidemics of "hypothetical-yet-plausible" pandemic pathogens in Canada; and 2) by having ready-to-go modelling methods that can be readily adapted to the features of an emerging pandemic pathogen and used for long-range forecasting of the epidemic in Canada, as well as to explore scenarios to support public health decisions on the use of interventions. Conclusion: There is a need for modelling expertise within public health organizations in Canada, linked to modellers in academia in a community of practice, within which relationships built outside of times of crisis can be applied to enhance modelling during public health emergencies. Key challenges to modelling for pandemic preparedness include the availability of linked public health, hospital and genomic data in Canada. [ABSTRACT FROM AUTHOR]
