The 2022 anti–zero Covid White Paper protests that erupted in China and its diaspora demonstrated the intertwinement of politics and performance in contemporary China. The symbolic dimensions of blank sheets of A4 paper and other performative tactics used in these demonstrations exemplify the shifting roles of performance art in the field of contemporary Chinese art.

Detecting sets of relevant patterns from a given dataset is an important challenge in data mining. The relevance of a pattern, also called utility in the literature, is a subjective measure and can be actually assessed from very different points of view. Rule-based languages like Answer Set Programming (ASP) seem well suited for specifying user-provided criteria to assess pattern utility in a form of constraints; moreover, declarativity of ASP allows for a very easy switch between several criteria in order to analyze the dataset from different points of view. In this paper, we make steps toward extending the notion of High-Utility Pattern Mining; in particular, we introduce a new framework that allows for new classes of utility criteria not considered in the previous literature. We also show how recent extensions of ASP with external functions can support a fast and effective encoding and testing of the new framework. To demonstrate the potential of the proposed framework, we exploit it as a building block for the definition of an innovative method for predicting ICU admission for COVID-19 patients. Finally, an extensive experimental activity demonstrates both from a quantitative and a qualitative point of view the effectiveness of the proposed approach. [ABSTRACT FROM AUTHOR]

Australia's mandatory vaccination policies have historically allowed for non-medical exemptions (NMEs), but this changed in 2016 when the Federal Government discontinued NMEs for childhood vaccination requirements. Australian states introduced further mandatory vaccination policies during the COVID-19 pandemic for a range of occupations including healthcare workers (HCWs). There is global evidence to suggest that medical exemptions (MEs) increase following the discontinuation of NMEs; the new swathe of COVID-19 mandatory vaccination policies likely also placed further pressure on ME systems in many jurisdictions. This paper examines the state of play of mandatory vaccination and ME policies in Australia by outlining the structure and operation of these policies for childhood vaccines, then for COVID-19, with a case study of HCW mandates. Next, the paper explores HCWs' experiences in providing vaccine exemptions to patients (and MEs in particular). Finally, the paper synthesizes existing literature and reflects on the challenges of MEs as a pressure point for people who do not want to vaccinate and for the clinicians who care for them, proposing areas for future research and action.

Aim: To explore how patients and general practice professionals in low-income neighborhoods experienced the increase of remote care during COVID-19., Background: As the GP (general practitioner) is the first point of contact in Dutch health care, there are concerns about access to remote care for patients from low-income neighborhoods. Now that general practice professionals have returned to the pre-pandemic ways of healthcare delivery, this paper looks back at experiences with remote care during COVID-19. It investigates experiences of both patients and general practice professionals with the approachability and appropriateness of remote care and their satisfaction., Methods: In this qualitative study, 78 patients and 18 GPs, 7 nurse practitioners and 6 mental health professionals were interviewed. Interviews were held on the phone and face-to-face in the native language of the participants., Findings: Remote care, especially telephone consultation, was generally well-approachable for patients from low-income neighborhoods. Contrarily, video calling was rarely used. This was partly because patients did not know how to use it. The majority of patients thought remote care was possible for minor ailments but would also still like to see the doctor face-to-face regularly. Patients were generally satisfied with remote care at the time, but this did not necessarily reflect their willingness to continue using it in the future. Moreover, there was lack in consensus among general practice professionals on the appropriateness of remote care for certain physical and mental complaints. Nurse practitioners and mental health professionals had a negative attitude toward remote care. In conclusion, it is important to take the opinions and barriers of patients and care providers into account and to increase patient-centered care elements and care provider satisfaction in remote care. Integrating remote care is not only important in times of crisis but also for future care that is becoming increasingly digitalized.

This study aimed to understand the population and contact tracer uptake of the quick response (QR)-code-based function of the New Zealand COVID Tracer App (NZCTA) used for digital contact tracing (DCT). We used a retrospective cohort of all COVID-19 cases between August 2020 and February 2022. Cases of Asian and other ethnicities were 2.6 times (adjusted relative risk (aRR) 2.58, 99 per cent confidence interval (95% CI) 2.18, 3.05) and 1.8 times (aRR 1.81, 95% CI 1.58, 2.06) more likely than Māori cases to generate a token during the Delta period, and this persisted during the Omicron period. Contact tracing organization also influenced location token generation with cases handled by National Case Investigation Service (NCIS) staff being 2.03 (95% CI 1.79, 2.30) times more likely to generate a token than cases managed by clinical staff at local Public Health Units (PHUs). Public uptake and participation in the location-based system independent of contact tracer uptake were estimated at 45%. The positive predictive value (PPV) of the QR code system was estimated to be close to nil for detecting close contacts but close to 100% for detecting casual contacts. Our paper shows that the QR-code-based function of the NZCTA likely made a negligible impact on the COVID-19 response in New Zealand (NZ) in relation to isolating potential close contacts of cases but likely was effective at identifying and notifying casual contacts.

Most countries in Africa deployed digital solutions to monitor progress in rolling out COVID-19 vaccines. A rapid assessment of existing data systems for COVID-19 vaccines in the African region was conducted between May and July 2022, in 23 countries. Data were collected through interviews with key informants, identified among senior staff within Ministries of Health, using a semi-structured electronic questionnaire. At vaccination sites, individual data were collected in paper-based registers in five countries (21.7%), in an electronic registry in two countries (8.7%), and in the remaining 16 countries (69.6%) using a combination of paper-based and electronic registries. Of the 18 countries using client-based digital registries, 11 (61%) deployed the District Health Information System 2 Tracker, and seven (39%), a locally developed platform. The mean percentage of individual data transcribed in the electronic registries was 61% ± 36% standard deviation. Unreliable Internet coverage (100% of countries), non-payment of data clerks' incentives (89%), and lack of electronic devices (89%) were the main reasons for the suboptimal functioning of digital systems quoted by key informants. It is critical for investments made and experience acquired in deploying electronic platforms for COVID-19 vaccines to be leveraged to strengthen routine immunization data management.

The Malaysian Government has initiated the National COVID-19 Immunisation Programme , known as PICK , to be a national strategy for addressing the spread of the coronavirus disease (COVID-19) pandemic across the country. Although the government intensified public awareness to increase program registration, the total number that registered in the state of Sabah, located in East Malaysia, was relatively low during August 2021, accounting for only 42.9% as compared to that of Peninsular Malaysia. Therefore, this paper examines the public perception toward the PICK program in Sabah based on 4 main components: safety, communication, psychology, and milieu. This study is based on the empirical findings drawn from 1024 respondents across Sabah using online Google Form surveys. This study adopts 5 methodologies for data analysis by using K-means clustering, mean score, Mann-Whitney U test, spatial analysis, and frequency analysis. It has been revealed that the percentage of respondents (categorized as Cluster 1) who have a negative perception toward the vaccination program is higher (55.9%) than those who have a positive perception (44.1%). This study further discovered that Cluster 1 has shown high skepticism regarding the vaccination program, which can be explained through the communication component (M = 3.33, SD = 0.588), especially Co2, Co3, Co1, and Co4. Following the communication factor, a chain of negative perceptions also affects other components such as safety, psychology, and milieu among Cluster 1, all of which contribute to poor participation in the PICK program. The study outcomes are extremely useful for informing local authorities to establish policies related to public interests, primarily in the areas of public health. Understanding the community's perspectives and their obstacles in participating in such programs may assist local authorities in developing or implementing public policies and campaigns that ensure such related public programs can be conducted more effectively in the future.

The coronavirus disease 2019 (COVID-19) pandemic has demonstrated the importance of stewardship of viral diagnostic tests to aid infection prevention efforts in healthcare facilities. We highlight diagnostic stewardship lessons learned during the COVID-19 pandemic and discuss how diagnostic stewardship principles can inform management and mitigation of future emerging pathogens in acute-care settings. Diagnostic stewardship during the COVID-19 pandemic evolved as information regarding transmission (eg, routes, timing, and efficiency of transmission) became available. Diagnostic testing approaches varied depending on the availability of tests and when supplies and resources became available. Diagnostic stewardship lessons learned from the COVID-19 pandemic include the importance of prioritizing robust infection prevention mitigation controls above universal admission testing and considering preprocedure testing, contact tracing, and surveillance in the healthcare facility in certain scenarios. In the future, optimal diagnostic stewardship approaches should be tailored to specific pathogen virulence, transmissibility, and transmission routes, as well as disease severity, availability of effective treatments and vaccines, and timing of infectiousness relative to symptoms. This document is part of a series of papers developed by the Society of Healthcare Epidemiology of America on diagnostic stewardship in infection prevention and antibiotic stewardship. 1 .

This paper summarizes key shifts in judicial decisions relating to public health powers during the pandemic and the implications of those decisions for public health practice. Then, it gives a preview and call for partnership in developing a legal framework for authority that guides public health to better activities, processes, and accountability in service of the public's health.

This paper challenges historically preconceived notions surrounding a minor's ability to make medical decisions, arguing that federal health law should be reformed to allow minors with capacity as young as age 12 to consent to their own Centers for Diseases Control and Prevention (CDC)-approved COVID-19 vaccinations. This proposal aligns with and expands upon current exceptions to limitations on adolescent decision-making. This analysis reviews the historic and current anti-vaccination sentiment, examines legal precedence and rationale, outlines supporting ethical arguments regarding adolescent decision-making, and offers rebuttals to anticipated ethical counterarguments.

An extensive body of demographic literature has described Jews as 'long-lifers'. From the mid-nineteenth century onwards, this pattern affected all age groups and was particularly well expressed among Jewish males but was also present among Jewish females. It held good independently of the Jews' socio-economic position. This became known as 'Jewish pattern of mortality'. This paper has two aims. The first aim is to show the impact of COVID-19 on Jewish mortality. This is a study of a global pandemic in the Jewish population which is, to the best of our knowledge, unique in its scope and quality. The second aim is to settle the finding of relatively high mortality from COVID-19 in certain Jewish communities ('Jewish penalty' in relation to COVID-19) with the notion of 'Jewish pattern of mortality'. The author proceeds to show that the status of Jews as a low mortality group under a Western epidemiological regime, when mortality and morbidity are dominated by non-communicable diseases, does not stand in contradiction to a higher vulnerability among Jews to coronavirus. Thus, the paper further develops understanding of mortality of Jews and serves as a contribution to ethnic and religious demography and epidemiology.

This paper examines how English courts have responded to the contract problems generated by the Covid-19 pandemic and considers what this tells us about future contract law development. In relation to consumers, the case law on pandemic-affected contracts, though limited, indicates that traditional contract doctrine does not necessarily produce beneficial outcomes for consumers. This further diminishes the importance of the common law in the consumer contracting context. In the commercial sector, contracting parties were encouraged by government and other organisations to co-operate with one another and act in good faith during the crisis, but this has not influenced the courts applying contract law in the pandemic aftermath. The emerging case law suggests that contract law has retained its commitment to certainty, freedom of contract and sanctity of contract, notwithstanding the extraordinary circumstances around the outbreak and its unpredictable effects on contracts. The unalloyed application of formal contract law in the post-pandemic case law augments the position of relational norms as extra-contractual in English law, putting the further judicial development of relational contract principles in doubt. The paper concludes that despite the considerable social and economic upheaval caused by the pandemic, its impact on contract law development is likely to be minimal. [ABSTRACT FROM AUTHOR]

Health authorities worldwide address older adults as a risk group for more serious illness and health complications associated with COVID-19, while social gerontologists have warned that addressing older adults as a risk group of COVID-19 bears the risk of reinforcing ageism. This paper empirically explores to what extent older adults perceive themselves as part of a COVID-19 risk group and how these perceptions influence their everyday lives and experiences of age and ageing. This paper draws upon data from a mixed-methods study on older adults' risk perceptions during COVID-19 in Lower Austria, including a representative survey on 521 adults (60+ years) and data from 20 semi-structured interviews. Approximately two-thirds of the respondents consider themselves at risk of COVID-19 and name age, in addition to pre-existing illness, as a contributing factor in this risk perception. Older adults with health constraints, and especially older men, have a higher probability of perceiving risk due to COVID-19. Additionally, older adults report that they experience being 'suddenly seen as old' or 'being put into a box' during the pandemic, which influenced their experiences and images of ageing. Our study provides insights into how perceived COVID-19 risk affects the everyday lives of older adults. Age-based categorisations of risk contribute to a shift in images of age and ageing, drawing on insecurity and risk, rather than successful and active ageing, to conceptualise later life.

The deadly outbreak of the COVID-19 pandemic has accompanied a worldwide surge in anti-Asian hate crimes and racial violence. In this paper, I experimentally assess the downstream effects of the health crisis on the racial attitudes of the American public. Survey respondents were randomly assigned to different messages about COVID-19 and its association with China and answered a battery of racial attitude questions, including a new measure of anti-Asian racial resentment. Across all outcome measures, I find null effects for both treatment messages, which suggests that racialized views toward Asians may be stable individual-level dispositions that have shaped American responses to the pandemic. Findings from this study have important implications for research on the far-reaching societal and political consequences of the pandemic in the United States and beyond. [ABSTRACT FROM AUTHOR]

Why are mistaken beliefs about COVID-19 so prevalent? Political identity, education and other demographic variables explain only part of the differences between people in their susceptibility to COVID-19 misinformation. This paper focuses on another explanation: epistemic vice. Epistemic vices are character traits that interfere with acquiring, maintaining, and transmitting knowledge. If the basic assumption of vice epistemology is right, then people with epistemic vices such as indifference to the truth or rigidity in their belief structures will tend to be more susceptible to believing COVID-19 misinformation. We carried out an observational study (US adult sample, n = 998) in which we measured the level of epistemic vice of participants using a novel Epistemic Vice Scale that captures features of the current competing analyses of epistemic vice in the literature. We also asked participants questions eliciting the extent to which they subscribe to myths and misinformation about COVID-19. We find overwhelming evidence to the effect that epistemic vice is associated with susceptibility to COVID-19 misinformation. In fact, the association turns out to be stronger than with political identity, educational attainment, scores on the Cognitive Reflection Test, personality, dogmatism, and need for closure. We conclude that this offers evidence in favor of the empirical presuppositions of vice epistemology. [ABSTRACT FROM AUTHOR]

The Covid-19 pandemic placed responsibility on the European Union (EU) to effectively mitigate this common challenge. An important aspect of the common fight against the virus was the collective procurement of vaccines. The initially slow process of vaccine delivery may have caused overall frustration within societies and may also have had a profound effect on people's assessment of their country's EU membership. This paper examines this assumption via unique panel data collected in Germany in three waves between November 2020 and August 2021. We show that citizens evaluated their country's EU membership negatively especially when the EU's progress on vaccinations was in its early stages. In addition, public assessment was particularly negative when vaccination progress was compared to the situation in the United Kingdom (UK). Overall, our findings point to volatile levels of EU support depending on respondents' perceptions of the success of the UK outside the EU. [ABSTRACT FROM AUTHOR]

The effective reproduction number $ R $ was widely accepted as a key indicator during the early stages of the COVID-19 pandemic. In the UK, the $ R $ value published on the UK Government Dashboard has been generated as a combined value from an ensemble of epidemiological models via a collaborative initiative between academia and government. In this paper, we outline this collaborative modelling approach and illustrate how, by using an established combination method, a combined $ R $ estimate can be generated from an ensemble of epidemiological models. We analyse the $ R $ values calculated for the period between April 2021 and December 2021, to show that this $ R $ is robust to different model weighting methods and ensemble sizes and that using heterogeneous data sources for validation increases its robustness and reduces the biases and limitations associated with a single source of data. We discuss how $ R $ can be generated from different data sources and show that it is a good summary indicator of the current dynamics in an epidemic. [ABSTRACT FROM AUTHOR]

This paper analyzes the effect of the COVID-19 pandemic on the within-household gender gap in relation to paid work hours in full-time employed heterosexual couples in Spain. Using the Spanish Labor Force Survey (2019–2020) and a difference-in-differences method, we analyze three stages of the pandemic: strict lockdown, de-escalation, and partial closures to study the short-term effects and potential medium-term effects on gender inequality in terms of paid work hours. Our results suggest that during the strict lockdown period there was a tendency to fall back on traditional family gendered patterns to manage the work–life balance, especially when young children are present in male-headed households. However, this phenomenon seems to be a short-term consequence of the pandemic. The sector of activity (essential or non-essential) has also played a key role, the gender gap increased in male-headed households with female partners employed in non-essential sectors.

The outbreak of COVID-19 has had a significant impact on societies and individual lives across the globe. In this paper, we address the impact of the pandemic and the protective measures on empirical social scientific ageing research through the lens of 'ethically important moments'. One of the most crucial measures for preventing the spread of the virus includes social distancing; therefore, empirical research methods based on person-to-person direct contact (as in interviews) and first-hand observation have been scaled back since 2020. For ageing research, the challenges are particularly pronounced due to the ongoing discussion regarding vulnerabilities associated with higher age and age-based discrimination. Hence, many researchers focusing on ageing are facing some difficult questions: How and under what conditions can we carry on with empirical research without putting our research participants and ourselves at risk? Firstly, we systematically identify the key dimensions and challenges that have shaped social scientific research during the lockdowns associated with the COVID-19 pandemic: fragmentation, fluidity, ambiguity and uncertainty. Then, using insights from two international research projects, we illustrate and critically reflect on the ethically important moments and practical dilemmas that have resulted from these pandemic challenges when researching with and about older adults.

Inter- and intragenerational relationships are known to be important in maintaining the wellbeing of older people. A key aspect of these relationships is the exchange of both emotional and instrumental social support. However, relatively little is known about how this exchange of support changes in the context of widespread disruption. The COVID-19 pandemic provides an opportunity to examine how older people's family relationships are impacted by such social change. The present qualitative study explores how older people in the United Kingdom experienced changes in inter- and intragenerational support during the COVID-19 pandemic. Participants (N = 33) were recruited through a large-scale nationally representative survey (https://www.sheffield.ac.uk/psychology-consortium-covid19). We asked how life had been pre-pandemic, how they experienced the first national lockdown and what the future might hold in store. The data were analysed using constructivist grounded theory. This paper focuses on the importance of family relationships and how they changed as a consequence of the pandemic. We found that the family support system had been interrupted, that there were changes in the methods of support and that feelings of belonging were challenged. We argue that families were brought into disequilibrium through changes in the exchange of inter- and intragenerational support. The important role of grandchildren for older adults was striking and challenged by the pandemic. The significance of social connectedness and support within the family had not changed during the pandemic, but it could no longer be lived in the same way. The desire to be close to family members and to support them conflicted with the risk of pandemic infection. Our study found support for the COVID-19 Social Connectivity Paradox: the need for social connectedness whilst maintaining social distance. This challenged family equilibrium, wellbeing and quality of life in older people. [ABSTRACT FROM AUTHOR]

Introduction: First responders' training and learning regarding how to handle a mass-casualty incident (MCI) is traditionally based on reading and/or training through computer-based scenarios, or sometimes through live simulations with actors. First responders should practice in realistic environments to narrow the theory-practice gap, and the possibility of repeating the training is important for learning. High-fidelity virtual reality (VR) is a promising tool to use for realistic and repeatable simulation training, but it needs to be further evaluated. The aim of this literature review was to provide a comprehensive description of the use of high-fidelity VR for MCI training by first responders. Methods: A systematic integrative literature review was used according to Whittemore and Knafl's descriptions. Databases investigated were PubMed, CINAHL Complete, Academic Search Ultimate, Web of Science, and ERIC to find papers addressing the targeted outcome. The electronic search strategy identified 797 potential studies. Seventeen studies were deemed eligible for final inclusion. Results: Training with VR enables repetition in a way not possible with live simulation, and the realism is similar, yet not as stressful. Virtual reality offers a cost-effective and safe learning environment. The usability of VR depends on the level of immersion, the technology being error-free, and the ease of use. Conclusions: This integrative review shows that high-fidelity VR training should not rule out live simulation, but rather serve as a complement. First responders became more confident and prepared for real-life MCIs after training with high-fidelity VR, but efforts should be made to solve the technical issues found in this review to further improve the usability.

The novel coronavirus (COVID-19) outbreak has affected living standards around the world, and pandemic anxiety has changed social habits. In this context, this paper investigates the relationship between fear of COVID-19 and quality of life, and assesses the mediating effect of loneliness on this relationship among a sample of older adults in Turkey. The study considers data from approximately 400 people, all of whom completed the CASP-19 Quality of Life Scale in Older People, the Loneliness Scale for the Elderly and the Fear of COVID-19 Scale. Confirmatory factor analyses were performed to confirm a one-factor structure for each instrument. Subsequently, mediation analysis, correcting for age as a continuous covariate, was performed to assess the nature of the relationship between fear and quality of life, and the extent to which that relationship is mediated by loneliness. Our study showed that there is a negative and direct relationship between loneliness and quality of life. Another important finding of our research is that fear of COVID-19 has a significant effect on loneliness. Finally, loneliness mediates the relation between fear of COVID-19 and quality of life. This finding strongly suggests that fear of COVID-19 influences quality of life via loneliness. This result is noteworthy, as we could not find any similar finding in the literature.

Background The adverse effects of COVID-19 and the associated restrictions on eating disorder populations have been discussed in recent literature. However, little is known about the presentation of cases with avoidant/restrictive food intake disorder (ARFID) during this period. Aims To explore the extent of the literature on the presentation of ARFID, and ARFID-like cases, during the COVID-19 pandemic. Method Cochrane Library, CINAHL (EBSCO), PsycINFO (EBSCO), EMBASE (Ovid) and Medline (Ovid) were searched for publications between March 2020 and May 2023. Google Scholar and reference lists were hand searched. At least two reviewers independently screened each paper. Narrative synthesis was used. Results Seven papers were included: four case reports and three cohort studies (total ARFID sample of 46). Included papers were assessed as having high (n = 3) or moderate (n = 4) quality. Findings did not suggest an increase in ARFID cases during the COVID-19 pandemic, although it is unclear if this is because of a lack of impact or underrecognition of ARFID. A need for a multidisciplinary approach to differentiate between ARFID and organic causes of ARFID-like presentations (e.g. gastrointestinal effects of COVID-19) was highlighted. Conclusions Publications specifically pertaining to ARFID presentations during the COVID-19 pandemic have been few. Papers found have been of small sample sizes and lack subanalyses for ARFID within broader eating disorder samples. Continued surveillance is needed to evaluate any COVID-19-specific effects on the development, identification, treatment and outcomes of ARFID.

This article examines UK newspaper coverage during the first wave of the COVID-19 pandemic March-August 2020. A qualitative framing analysis of public messaging on age in five high circulation newspapers provides a detailed account of who is deemed to be at risk of dying from COVID-19. Newspapers represent older people as most at risk, with disability as a secondary factor. Reports on who is responsible, who is at risk, and who is to blame for deaths from COVID-19 are framed as issues of public health and generational fairness, with individual responsibility occupying a prominent role. We also find two counter-frames. First, in letters to the editor, older people's pleas for freedom are framed as a fight for their civil liberties. Second, newspapers praise 99-year-old Captain Tom Moore and frame his behaviour as a source of national pride. We identify this as positive ageism. We conclude that reporting across progressive and conservative newspapers reflects age-based stereotypes and paternalism towards older people. Public figures are represented as scapegoats or heroes, offering distraction from the less newsworthy fact that long-term under-investment in social care increased the risk of dying amongst the old and disabled during the pandemic.

The COVID-19 pandemic of 2020 was one of the rare events that shocked almost every world government simultaneously, thus creating an unusual opportunity to understand how political institutions shape policy decisions. There have been many analyses of what governments did. We focus instead on what they could do, focusing on the institutional politics of agency – how institutions empower rather than how they constrain, and how they affect public policy decisions. We examine public health measures in the first wave (March-September 2020) in Brazil, India, and the U.S. to understand how the interplay of institutions in a complex federal context shaped COVID-19 policy-responses. We find similar patterns of concentrated federal executive agency with limited constraints. In each case, when federal leadership failed public health policy responses, federated, subnational states were left to compensate for these inefficiencies without necessary resources.

How do cultural biases, trust in government, and perceptions of risk and protective actions influence compliance with regulation of COVID-19? Analyzing Chinese (n = 646) and American public opinion samples (n = 1,325) from spring 2020, we use Grid–Group Cultural Theory and the Protective Action Decision Model to specify, respectively, cultural influences on public risk perceptions and decision-making regarding protective actions. We find that cultural biases mostly affect protective actions indirectly through public perceptions. Regardless of country, hierarchical cultural biases increase protective behaviors via positive perceptions of protective actions. However, other indirect effects of cultural bias via public perceptions vary across both protective actions and countries. Moreover, trust in government only mediates the effect of cultural bias in China and risk perception only mediates the effect of cultural bias in the United States. Our findings suggest that regulators in both countries should craft regulations that are congenial to culturally diverse populations. [ABSTRACT FROM AUTHOR]

Background: The COVID-19 pandemic disrupted many areas of life, including culturally accepted practices at end-of-life care, funeral rites, and access to social, community, and professional support. This survey investigated the mental health outcomes of Australians bereaved during this time to determine how these factors might have impacted bereavement outcomes. Methods: An online survey indexing pandemic and bereavement experiences, levels of grief, depression, anxiety, and health, work, and social impairment. Latent class analysis (LCA) was used to identify groups of individuals who shared similar symptom patterns. Multinomial regressions identified pandemic-related, loss-related, and sociodemographic correlates of class membership. Results: 1911 Australian adults completed the survey. The LCA identified four classes: low symptoms (46.8%), grief (17.3%), depression/anxiety (17.7%), and grief/depression/anxiety (18.2%). The latter group reported the highest levels of health, work, and social impairment. The death of a child or partner and an inability to care for the deceased due to COVID-19 public health measures were correlated with grief symptoms (with or without depression and anxiety). Preparedness for the person's death and levels of pandemic-related loneliness and social isolation differentiated all four classes. Unemployment was associated with depression/anxiety (with or without grief). Conclusions: COVID-19 had profound impacts for the way we lived and died, with effects that are likely to ricochet through society into the foreseeable future. These lessons learned must inform policymakers and healthcare professionals to improve bereavement care and ensure preparedness during and following future predicted pandemics to prevent negative impacts.

Background: Enduring ethnic inequalities exist in mental healthcare. The COVID-19 pandemic has widened these. Aims: To explore stakeholder perspectives on how the COVID-19 pandemic has increased ethnic inequalities in mental healthcare. Method: A qualitative interview study of four areas in England with 34 patients, 15 carers and 39 mental health professionals from National Health Service (NHS) and community organisations (July 2021 to July 2022). Framework analysis was used to develop a logic model of inter-relationships between pre-pandemic barriers and COVID-19 impacts. Results: Impacts were largely similar across sites, with some small variations (e.g. positive service impacts of higher ethnic diversity in area 2). Pre-pandemic barriers at individual level included mistrust and thus avoidance of services and at a service level included the dominance of a monocultural model, leading to poor communication, disengagement and alienation. During the pandemic remote service delivery, closure of community organisations and media scapegoating exacerbated existing barriers by worsening alienation and communication barriers, fuelling prejudice and division, and increasing mistrust in services. Some minority ethnic patients reported positive developments, experiencing empowerment through self-determination and creative activities. Conclusions: During the COVID-19 pandemic some patients showed resilience and developed adaptations that could be nurtured by services. However, there has been a reduction in the availability of group-specific NHS and third-sector services in the community, exacerbating pre-existing barriers. As these developments are likely to have long-term consequences for minority ethnic groups' engagement with mental healthcare, they need to be addressed as a priority by the NHS and its partners.

When do cross-national comparisons enable citizens to hold governments accountable? According to recent work in comparative politics, benchmarking across borders is a powerful mechanism for making elections work. However, little attention has been paid to the choice of benchmarks and how they shape democratic accountability. We extend existing theories to account for endogenous benchmarking. Using the COVID-19 pandemic as a test case, we embedded experiments capturing self-selection and exogenous exposure to benchmark information from representative surveys in France, Germany, and the UK. The experiments reveal that when individuals have the choice, they are likely to seek out congruent information in line with their prior view of the government. Moreover, going beyond existing experiments on motivated reasoning and biased information choice, endogenous benchmarking occurs in all three countries despite the absence of partisan labels. Altogether, our results suggest that endogenous benchmarking weakens the democratic benefits of comparisons across borders. [ABSTRACT FROM AUTHOR]

This article uses the French Rassemblement National (RN) as a case study to examine how the populist radical right (PRR) prepares for a world after COVID-19 dominated by climate change concerns. Research suggests that certain measures introduced to contain the virus – such as the establishment of strict border and travel restrictions – may legitimize the PRR's protectionist and anti-immigration agendas, yet few have examined whether or how PRR parties have used COVID-19 to promote their environmental agenda. If anything, the expectation has been that the pandemic would hurt the PRR precisely because its effects, unlike climate change, cannot be dismissed as a "hoax." This view overlooks not only the "environmental turn" recently taken by several PRR parties but also the possibility that public awareness of the causal link between climate change and COVID-19 may work to their advantage. The analysis presented in this article highlights this possibility, showing that the RN used COVID-19 not only to capitalize on anti-immigrant sentiment but also to bolster its self-image as a champion of environmental protection.

Classic theories of public opinion suggest that negative shocks can undermine system support in weak democracies, but scant work has systematically assessed this thesis. We identify Peru's explosive Vacuna-gate scandal as a most-likely case for finding a connection between corruption and political support. The scandal's unexpected revelation in the middle of the 2021 AmericasBarometer Peru survey created conditions for a natural experiment. Applying an unexpected-event-during-survey design, we consider the consequences of the scandal for perceptions of corruption, system support, and support for democracy. We find robust evidence that the scandal increased even already high perceptions of corruption and lowered system support. Contrary to expectations derived from prior theories, we find no effect on explicit support for democracy. In the conclusion, we discuss the nuanced ways that scandal may shape democratic stability.

International crises, most recently the Covid-19 pandemic and Russia's invasion of Ukraine, often radically change our view of the world and our place within it. The European Union (EU) has been particularly impacted by these developments because these crises have accentuated some of its ontological and epistemological uncertainties and insecurities. While the EU's resilience turn initiated by the EU Global Strategy of 2016 aimed at strengthening the EU's ability to prepare and recover from external shocks and crises, since then, the concept of resilience has undergone a transformation. In recent years, we have seen the EU turning back in on itself and abandoning the radical aspects of resilience. Hence a paradox has emerged – the more complex the problems faced by the EU, the more it turns away from the logics of complexity present in the idea of resilience. In this article, we examine this conceptual shift through the lenses of concepts in action and the way these have reflected changes in the external context, but also power coalitions and institutional path dependencies. This argument will be explored by examining the recently adopted Strategic Compass and the EU's Recovery and Resilience Facility (RRF). [ABSTRACT FROM AUTHOR]

Objective: Comprehensive studies examining longitudinal predictors of dietary change during the coronavirus disease 2019 pandemic are lacking. Based on an ecological framework, this study used longitudinal data to test if individual, social and environmental factors predicted change in dietary intake during the peak of the coronavirus 2019 pandemic in Los Angeles County and examined interactions among the multilevel predictors. Design: We analysed two survey waves (e.g. baseline and follow-up) of the Understanding America Study, administered online to the same participants 3 months apart. The surveys assessed dietary intake and individual, social, and neighbourhood factors potentially associated with diet. Lagged multilevel regression models were used to predict change from baseline to follow-up in daily servings of fruits, vegetables and sugar-sweetened beverages. Setting: Data were collected in October 2020 and January 2021, during the peak of the coronavirus disease 2019 pandemic in Los Angeles County. Participants: 903 adults representative of Los Angeles County households. Results: Individuals who had depression and less education or who identified as non-Hispanic Black or Hispanic reported unhealthy dietary changes over the study period. Individuals with smaller social networks, especially low-income individuals with smaller networks, also reported unhealthy dietary changes. After accounting for individual and social factors, neighbourhood factors were generally not associated with dietary change. Conclusions: Given poor diets are a leading cause of death in the USA, addressing ecological risk factors that put some segments of the community at risk for unhealthy dietary changes during a crisis should be a priority for health interventions and policy.

Objective: This study aimed to analyse the spatial and temporal patterns of disease burden attributed to high BMI (DB-hBMI) from 1990 to 2019 in Belt and Road Initiative (BRI) countries, in light of increasing hBMI prevalence worldwide. Design: The study was a secondary analysis of Global Burden of Disease 2019 (GBD 2019) that analysed (using Joinpoint regression analysis) numbers and the age-standardised rate of mortality and disability-adjusted life years (DALY) of hBMI-induced diseases and their trends from 1990 to 2019 and in the final decade. Setting: GBD 2019 study data for BRI countries were categorised by country, age, gender and disease. Participants: GBD 2019 data were used to analyse DB-hBMI in BRI countries. Results: In 2019, China, India and Russia reported the highest mortality and DALY among BRI countries. From 1990 to 2019, the age-standardised DALY increased in Southeast Asia and South Asia, whereas many European countries saw declines. Notably, Bangladesh, Nepal and Vietnam showed the steepest increases, with average annual percentage change (AAPC) values of 4·42 %, 4·19 % and 4·28 %, respectively (all P  < 0·05). In contrast, Israel, Slovenia and Poland experienced significant reductions, with AAPC values of –1·70 %, –1·63 % and –1·58 %, respectively (all P  < 0·05). The most rapid increases among males were seen in Vietnam, Nepal and Bangladesh, while Jordan, Poland and Slovenia recorded the fastest declines among females. Across most BRI countries, the burden of diabetes and kidney diseases related to hBMI showed a significant uptrend. Conclusion: DB-hBMI varies significantly by region, age, gender and disease type across BRI countries. It can pose a substantial threat to public health. [ABSTRACT FROM AUTHOR]

Objective: The present study investigated potential predictors of food insecurity among UK university students during the COVID-19 pandemic. Design: Close-ended questionnaire administered to a cross-sectional sample of UK university students. Setting: Data were collected using an online survey platform in October 2020, during the COVID-19 pandemic. Participants: A nationally representative sample of UK university students (n 640). Results: Odds ratios (OR) obtained from logistic regression were statistically significant for three measures of economic hardship. First, students who relied on financial aid from student loans were 1·9 times more likely to report being food insecure than students who did not rely on financial aid from student loans. Second, students who could not pay their utility bill (v. those that could pay) were 3·1 times the odds of being food insecure. Finally, as perceived difficulty in paying for accommodation increased across the sample, the odds of being food insecure also increased (OR = 1·9). We also found that students who were recently ill were 2·2 times more likely to be food insecure compared with students who were not recently ill. We did not find any evidence that testing positive for COVID-19 predicted food insecurity, and university supplied food parcels/boxes did not reduce student food insecurity. Conclusions: Both economic factors and illness play a significant role in self-reported food insecurity in higher education students during pandemic lockdown. Further research is needed to explore food insecurity, economic factors and illness outside of a pandemic context. [ABSTRACT FROM AUTHOR]

Objectives: Several meta-analyses have suggested the beneficial effect of vitamin D on patients infected with severe acute respiratory syndrome coronavirus-2. This umbrella meta-analysis aims to evaluate influence of vitamin D supplementation on clinical outcomes and the mortality rate of COVID-19 patients. Design: Present study was designed as an umbrella meta-analysis. The following international databases were systematically searched till March 2023: Web of Science, PubMed, Scopus, and Embase. Settings: Random-effects model was employed to perform meta-analysis. Using AMSTAR critical evaluation tools, the methodological quality of the included meta-analyses was evaluated. Participants: Adult patients suffering from COVID-19 were studied. Results: Overall, 13 meta-analyses summarising data from 4 randomised controlled trial and 9 observational studies were identified in this umbrella review. Our findings revealed that vitamin D supplementation and status significantly reduced mortality of COVID-19 [Interventional studies: (ES = 0·42; 95 % CI: 0·10, 0·75, P < 0·001; I 2 = 20·4 %, P = 0·285) and observational studies (ES = 1·99; 95 % CI: 1·37, 2·62, P < 0·001; I 2 = 00·0 %, P = 0·944). Also, vitamin D deficiency increased the risk of infection and disease severity among patients. Conclusion: Overall, vitamin D status is a critical factor influencing the mortality rate, disease severity, admission to intensive care unit and being detached from mechanical ventilation. It is vital to monitor the vitamin D status in all patients with critical conditions including COVID patients. [ABSTRACT FROM AUTHOR]

Objective: We assessed the impact of the COVID-19 pandemic and the protocol adaptations on cost and cost-effectiveness of community management of acute malnutrition (CMAM) program in South Sudan. Design: Retrospective program expenditure-based analysis of non-governmental organisation (NGO) CMAM programs for COVID-19 period (April 2020–December 2021) in respect to pre-COVID period (January 2019–March 2020). Setting: Study was conducted as part of a bigger evaluation study in South Sudan. Participants: International and national NGOs operating CMAM programs under the nutrition cluster participated in the study. Results: The average cost per child recovered from the programme declined by 20 % during COVID from $133 (range: $34–1174) pre-COVID to $107 (range: $20–333) during COVID. The cost per child recovered was negatively correlated with programme size (pre-COVID r-squared = 0·58; during COIVD r-squared = 0·50). Programmes with higher enrollment were cheaper compared with those with low enrolment. Salaries, ready to use food and community activities accounted for over two-thirds of the cost per recovery during both pre-COVID (69 %) and COVID (79 %) periods. While cost per child recovered decreased during COVID period, it did not negatively impact on the programme outcome. Enrolment increased by an average of 19·8 % and recovery rate by 4·6 % during COVID period. Conclusions: Costs reduced with no apparent negative implication on recovery rates after implementing the COVID CMAM protocol adaptations with a strong negative correlation between cost and programme size. This suggests that investing in capacity, screening and referral at existing CMAM sites to enable expansion of caseload maybe a preferable strategy to increasing the number of CMAM sites in South Sudan.

From 2020 to December 2022, China implemented strict measures to contain the spread of severe acute respiratory syndrome coronavirus 2. However, despite these efforts, sustained outbreaks of the Omicron variants occurred in 2022. We extracted COVID-19 case numbers from May 2021 to October 2022 to identify outbreaks of the Delta and Omicron variants in all provinces of mainland China. We found that omicron outbreaks were more frequent (4.3 vs. 1.6 outbreaks per month) and longer-lasting (mean duration: 13 vs. 4 weeks per outbreak) than Delta outbreaks, resulting in a total of 865,100 cases, of which 85% were asymptomatic. Despite the average Government Response Index being 12% higher (95% confidence interval (CI): 9%, 15%) in Omicron outbreaks, the average daily effective reproduction number (Rt) was 0.45 higher (95% CI: 0.38, 0.52, p  < 0.001) than in Delta outbreaks. Omicron outbreaks were suppressed in 32 days on average (95% CI: 26, 39), which was substantially longer than Delta outbreaks (14 days; 95% CI: 11, 19; p  = 0.004). We concluded that control measures effective against Delta could not contain Omicron outbreaks in China. This highlights the need for continuous evaluation of new variants' epidemiology to inform COVID-19 response decisions. [ABSTRACT FROM AUTHOR]

In February 2021, a cluster of Beta variant (B.1.351) coronavirus disease 2019 (COVID-19) cases were identified in an apartment building located in Northern Ontario, Canada. Most cases had no known contact with each other. Objectives of this multi-component outbreak investigation were to better understand the social and environmental factors that facilitated the transmission of COVID-19 through this multi-unit residential building (MURB). A case–control study examined building-specific exposures and resident behaviours that may have increased the odds of being a case. A professional engineer assessed the building's heating, ventilation, and air-conditioning (HVAC) systems. Whole-genome sequencing and an in-depth genomic analysis were performed. Forty-five outbreak-confirmed cases were identified. From the case–control study, being on the upper floors (OR: 10.4; 95% CI: 1.63–66.9) and within three adjacent vertical lines (OR: 28.3; 3.57–225) were both significantly associated with being a case of COVID-19, after adjusting for age. There were no significant differences in reported behaviours, use of shared spaces, or precautions taken between cases and controls. An assessment of the building's ventilation found uncontrolled air leakage between apartment units. A single genomic cluster was identified, where most sequences were identical to one another. Findings from the multiple components of this investigation are suggestive of aerosol transmission between units. [ABSTRACT FROM AUTHOR]

Aviation passenger screening has been used worldwide to mitigate the translocation risk of SARS-CoV-2. We present a model that evaluates factors in screening strategies used in air travel and assess their relative sensitivity and importance in identifying infectious passengers. We use adapted Monte Carlo simulations to produce hypothetical disease timelines for the Omicron variant of SARS-CoV-2 for travelling passengers. Screening strategy factors assessed include having one or two RT-PCR and/or antigen tests prior to departure and/or post-arrival, and quarantine length and compliance upon arrival. One or more post-arrival tests and high quarantine compliance were the most important factors in reducing pathogen translocation. Screening that combines quarantine and post-arrival testing can shorten the length of quarantine for travelers, and variability and mean testing sensitivity in post-arrival RT-PCR and antigen tests decrease and increase with the greater time between the first and second post-arrival test, respectively. This study provides insight into the role various screening strategy factors have in preventing the translocation of infectious diseases and a flexible framework adaptable to other existing or emerging diseases. Such findings may help in public health policy and decision-making in present and future evidence-based practices for passenger screening and pandemic preparedness. [ABSTRACT FROM AUTHOR]

There is limited information on the antibody responses against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in subjects from developing countries with populations having a high incidence of co-morbidities. Here, we analysed the immunogenicity of homologous schemes using the ChAdOx1-S, Sputnik V, or BNT162b2 vaccines and the effect of a booster dose with ChAdOx1-S in middle-aged adults who were seropositive or seronegative to the SARS-CoV-2 spike protein before vaccination. The study was conducted post-vaccination with a follow-up of 4 months for antibody titre using enzyme-linked immunosorbent assay (ELISA) and pseudovirus (PV) neutralization assays (PNAs). All three vaccines elicited a superior IgG anti-receptor-binding domain (RBD) and neutralization response against the Alpha and Delta variants when administered to individuals with a previous infection by SARS-CoV-2. The booster dose spiked the neutralization activity among individuals with and without a prior SARS-CoV-2 infection. The ChAdOx1-S vaccine induced weaker antibody responses in infection-naive subjects. A follow-up of 4 months post-vaccination showed a drop in antibody titre, with about 20% of the infection-naive and 100% of SARS-CoV-2 pre-exposed participants with detectable neutralization capacity against Alpha pseudovirus (Alpha-PV) and Delta PV (Delta-PV). Our observations support the use of different vaccines in a country with high seroprevalence at the vaccination time. [ABSTRACT FROM AUTHOR]

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in 2019 in China and rapidly spread worldwide, leading to a pandemic. The threat of SARS-CoV-2 is subsiding as most people have acquired sufficient antibodies through vaccination and/or infection to prevent severe COVID-19. After the emergence of the omicron variants, the seroprevalence of antibodies against the N protein elicited by SARS-CoV-2 infection ranged from 44.4% to 80.2% in countries other than Japan. Here, we assessed the seroprevalence in Japan before and after the appearance of omicron variants. Serosurveillance of antibodies against N was conducted between December 2021 and March 2023 in Japan. In total, 7604 and 3354 residual serum or plasma samples were collected in the Tokyo metropolitan area and Sapporo, respectively. We found that the seroprevalence in representative regions of Japan increased approximately 3% to 23% after the emergence of the omicron variants. We also found higher seroprevalence among the young compared with the elderly. Our findings indicate that unlike other countries, most of the Japanese population has not been infected, raising the possibility of future SARS-CoV-2 epidemics in Japan. [ABSTRACT FROM AUTHOR]

During the COVID-19 pandemic in Germany, a variety of societal activities were restricted to minimize direct personal interactions and, consequently, reduce SARS-CoV-2 transmission. The aim of the CoViRiS study was to investigate whether certain behaviours and societal factors were associated with the risk of sporadic symptomatic SARS-CoV-2 infections. Adult COVID-19 cases and frequency-matched population controls were interviewed by telephone regarding activities that involved contact with other people during the 10 days before illness onset (cases) or before the interview (controls). Associations between activities and symptomatic SARS-CoV-2 infection were analysed using logistic regression models adjusted for potential confounding variables. Data of 859 cases and 1 971 controls were available for analysis. The risk of symptomatic SARS-CoV-2 infection was lower for individuals who worked from home (adjusted odds ratio (aOR) 0.5; 95% confidence interval (CI) 0.3–0.6). Working in a health care setting was associated with a higher risk (aOR: 1.5; 95% CI: 1.1–2.1) as were private indoor contacts, personal contacts that involved shaking hands or hugging, and overnight travelling within Germany. Our results are in line with some of the public health recommendations aimed at reducing interpersonal contacts during the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

This study aimed to understand rural–urban differences in the uptake of COVID-19 vaccinations during the peak period of the national vaccination roll-out in Aotearoa New Zealand (NZ). Using a linked national dataset of health service users aged 12+ years and COVID-19 immunization records, age-standardized rates of vaccination uptake were calculated at fortnightly intervals, between June and December 2021, by rurality, ethnicity, and region. Rate ratios were calculated for each rurality category with the most urban areas (U1) used as the reference. Overall, rural vaccination rates lagged behind urban rates, despite early rapid rural uptake. By December 2021, a rural–urban gradient developed, with age-standardized coverage for R3 areas (most rural) at 77%, R2 81%, R1 83%, U2 85%, and U1 (most urban) 89%. Age-based assessments illustrate the rural–urban vaccination uptake gap was widest for those aged 12–44 years, with older people (65+) having broadly consistent levels of uptake regardless of rurality. Variations from national trends are observable by ethnicity. Early in the roll-out, Indigenous Māori residing in R3 areas had a higher uptake than Māori in U1, and Pacific peoples in R1 had a higher uptake than those in U1. The extent of differences in rural–urban vaccine uptake also varied by region. [ABSTRACT FROM AUTHOR]

A local COVID-19 outbreak with two community clusters occurred in a large industrial city, Shaoxing, China, in December 2021 after serial interventions were imposed. We aimed to understand the reason by analysing the characteristics of the outbreak and evaluating the effects of phase-adjusted interventions. Publicly available data from 7 December 2021 to 25 January 2022 were collected to analyse the epidemiological characteristics of this outbreak. The incubation period was estimated using Hamiltonian Monte Carlo method. A well-fitted extended susceptible-exposed-infectious-recovered model was used to simulate the impact of different interventions under various combination of scenarios. There were 387 SARS-CoV-2-infected cases identified, and 8.3% of them were initially diagnosed as asymptomatic cases. The estimated incubation period was 5.4 (95% CI 5.2–5.7) days for all patients. Strengthened measures of comprehensive quarantine based on tracing led to less infections and a shorter duration of epidemic. With a same period of incubation, comprehensive quarantine was more effective in containing the transmission than other interventions. Our findings reveal an important role of tracing and comprehensive quarantine in blocking community spread when a cluster occurred. Regions with tense resources can adopt home quarantine as a relatively affordable and low-impact intervention measure compared with centralized quarantine. [ABSTRACT FROM AUTHOR]
