Background: Quarantine is one of the most effective interventions to contain an infectious disease outbreak, yet it is one of the most disruptive. We investigated the quarantine of an entire village to better understand risk communication requirements for groups., Methods: We conducted a cross-sectional, mixed-methods survey study on a single cohort of adult residents in Neustadt am Rennsteig, Germany, six weeks after the removal of a 14-day mandatory community quarantine. The survey response rate was 33% (289/883 residents)., Findings: Survey participants reported a lack of information on the quarantine implementation process. What authorities communicated was not necessarily what residents desired to know. While inhabitants used social media and telephones to communicate with each other, the official information sources were regional radio, television, newspapers and official websites. Public health authorities did not employ social media communication to engage with their communities. Despite a lack of information, the majority of respondents stated that they had complied with the quarantine and they expressed little sympathy for those who violated the quarantine. After lifting the quarantine, many respondents continued to avoid places where they suspected a significant risk of infection, such as family and friends' homes, doctor's offices and grocery stores., Interpretation: The survey participants utilised existing social networks to disseminate vital information and stabilise its group identity and behaviour (quarantine compliance). The authorities communicated sparsely in a unidirectional, top-down manner, without engaging the community. Despite the lack of official information, the social coherency of the group contributed to considerate and compliant conduct, but participants expressed dissatisfaction with official leadership and asked for more attention., Conclusion: Public health risk communication must engage with communities more effectively. This necessitates a deeper comprehension of groups, their modes of communication and their social needs., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Licht et al.

Purpose: Some patients experience long-term sequelae after infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, despite a present post-COVID condition, defined as "any symptom lasting longer than 12 weeks," only a subset of patients search for medical help and therapy., Method: We invited all adults with a positive real-time polymerase chain reaction (RT-PCR) for SARS-CoV-2 between March 2020 and September 2021 (n = 4091) in the city of Jena to answer a standardized questionnaire including demographic information, the course of the acute infection and current health status. K-means-clustering of quality of life (QoL) was used to explore post-COVID subgroups., Results: A total of 909 participants at a median interval of 367 (IQR 291/403) days after acute infection were included in the analysis. Of those, 643 (70.7%) complained of having experienced persistent symptoms at the time of the survey. Cluster analysis based on QoL revealed two subgroups of people with persistent post-COVID symptoms. Whereas 189/643 participants (29.4%) showed markedly diminished QoL, normal QoL was detected in 454/643 individuals (70.6%)., Conclusion: Despite persistent symptoms being reported by nearly three quarters of participants, only one-third of these described a significant reduction in QoL (cluster 1), whereas the other two-thirds reported a near-normal QoL (cluster 2), thus indicating a differentiation between "post-COVID disease" and "post-COVID condition". The prevalence of clinically relevant post-COVID disease was at least 20.7%. Health policies should focus on this subset., (© 2022. The Author(s).)

Risk communication of public institutions should support the population in the decision-making process in the event of existing risks. It plays a particularly important role in health emergencies such as the SARS-CoV‑2 pandemic. After the SARS outbreak in 2003, the World Health Organization (WHO) revised its International Health Regulations (IHR 2005) and called for risk communication to be established as a core area of health policy in all member countries. While the emphasis on health policy was welcomed, the potential for risk communication in this area has not yet been fully exploited. Reasons include discrepancies in the understanding of risk communication and the large number of available methods.This discussion article is intended to help establish a new understanding of risk communication in public health emergencies (emergency risk communication - ERC). It is suggested that, in addition to the risks, the opportunities of the crisis should be included more and that risk communication should be understood more as a continuous process that can be optimized at various points. The "Earlier-Faster-Smoother-Smarter" approach and in particular the earlier detection of health risks ("Earlier") could support the management of public health emergencies in the future., (© 2022.

Background: Separating ill or possibly infectious people from their healthy community is one of the core principles of non-pharmaceutical interventions. However, there is scarce evidence on how to successfully implement quarantine orders. We investigated a community quarantine for an entire village in Germany (Neustadt am Rennsteig, March 2020) with the aim of better understanding the successful implementation of quarantine measures., Methods: This cross-sectional survey was conducted in Neustadt am Rennsteig six weeks after the end of a 14-day mandatory community quarantine. The sample size consisted of 562 adults (64% of the community), and the response rate was 295 adults, or 52% (33% of the community)., Findings: National television was reported as the most important channel of information. Contact with local authorities was very limited, and partners or spouses played a more important role in sharing information. Generally, the self-reported information level was judged to be good (211/289 [73.0%]). The majority of participants (212/289 [73.4%]) approved of the quarantine, and the reported compliance was 217/289 (75.1%). A self-reported higher level of concern as well as a higher level of information correlated positively with both a greater acceptance of quarantine and self-reported compliant behaviour., Interpretation: The community quarantine presented a rare opportunity to investigate a public health intervention for an entire community. In order to improve the implementation of public health interventions, public health risk communication activities should be intensified to increase both the information level (potentially leading to better compliance with community quarantine) and the communication level (to facilitate rapport and trust between public health authorities and their communities)., Competing Interests: The authors have declared that no competing interests exist.

Background: The reported mortality for sepsis and septic shock varies between 15% and 59% in international comparison. For Germany, the number of studies is limited. Previous estimations of mortality in Germany are outdated or based on claims data analyses. Various authors discuss whether lacking quality initiatives and treatment standards in Germany could cause higher mortality for sepsis. This contrasts with the internationally well-recognized performance of the German intensive care infrastructure during the COVID-19 pandemic., Objectives: The objectives of this systematic review and meta-analysis were to estimate 30-day and 90-day mortality of patients with sepsis and patients with septic shock in Germany and to compare the mortality with that of other industrialized regions (Europe, North America)., Material and Methods: A systematic literature search included interventional and observational studies published between 2009 and 2020 in PubMed and the Cochrane Library that analyzed adult patients with sepsis, severe sepsis and septic shock in Europe and North America. Studies with less than 20 patients were excluded. The 30-day and 90-day mortality for sepsis and septic shock were pooled separately for studies conducted in Germany, Europe (excluding Germany) and North America in a meta-analysis using a random effects model. Mortality over time was analyzed in a linear regression model., Results: Overall, 134 studies were included. Of these, 15 studies were identified for the estimation of mortality in Germany, covering 10,434 patients, the number of patients per study ranged from 28 to 4183 patients. The 30-day mortality for sepsis was 26.50% (95% confidence interval, CI: 19.86-33.15%) in Germany, 23.85% (95% CI: 20.49-27.21%) in Europe (excluding Germany) and 19.58% (95% CI: 14.03-25.14%) in North America. The 30-day mortality for septic shock was 30.48% (95% CI: 29.30-31.67%) in Germany, 34.57% (95% CI: 33.51-35.64%) in Europe (excluding Germany) and 33.69% (95% CI: 31.51-35.86%) in North America. The 90-day mortality for septic shock was 38.78% (95% CI: 32.70-44.86%) in Germany, 41.90% (95% CI: 38.88-44.91%) in Europe (excluding Germany) and 34.41% (95% CI: 25.66-43.16%) in North America. A comparable decreasing trend in sepsis 30-day mortality was observed in all considered regions since 2009., Conclusion: Our analysis does not support the notion that mortality related to sepsis and septic shock in Germany is higher in international comparison. A higher mortality would not be obvious either, since intensive care, for example also during the COVID-19 pandemic, is regarded as exemplary in Germany and the structural quality, such as the number of intensive care beds per 100,000 inhabitants, is high in international comparison. Nevertheless, deficits could also exist outside intensive care medicine. A comparison of international individual studies should take greater account of the structure of healthcare systems, the severity of disease and the limitations resulting from the data sources used., (© 2021.

Infectious disease outbreaks can have significant impact on individual health, national economies, and social well-being. Through early detection of an infectious disease, the outbreak can be contained at the local level, thereby reducing adverse effects on populations. Significant time and funding have been invested to improve disease detection timeliness. However, current evaluation methods do not provide evidence-based suggestions or measurements on how to detect outbreaks earlier. Key conditions for earlier detection and their influencing factors remain unclear and unmeasured. Without clarity about conditions and influencing factors, attempts to improve disease detection remain ad hoc and unsystematic. Methods: We developed a generic five-step disease detection model and a novel methodology to use for data collection, analysis, and interpretation. Data was collected in two workshops in Southeast Europe ( n = 33 participants) and Southern and East Africa ( n = 19 participants), representing mid- and low-income countries. Through systematic, qualitative, and quantitative data analyses, we identified key conditions for earlier detection and prioritized factors that influence them. As participants joined a workshop format and not an experimental setting, no ethics approval was required. Findings: Our analyses suggest that governance is the most important condition for earlier detection in both regions. Facilitating factors for earlier detection are risk communication activities such as information sharing, communication, and collaboration activities. Impeding factors are lack of communication, coordination, and leadership. Interpretation: Governance and risk communication are key influencers for earlier detection in both regions. However, inadequate technical capacity, commonly assumed to be a leading factor impeding early outbreak detection, was not found a leading factor. This insight may be used to pinpoint further improvement strategies., (Copyright © 2020 Steele, Orefuwa, Bino, Singer, Lutwama and Dickmann.)

In spring 2016, an updated sepsis definition (Sepsis-3) introduced a new explanation for the clinical picture of sepsis. Until then, sepsis had been understood as a "systemic inflammatory response syndrome (SIRS)" resulting from infection. An improved understanding of the molecular mechanisms and broad epidemiological studies of the clinical appearance shifted the focus from the inflammatory response to the multicausal tissue damage resulting in organ dysfunction. This paradigm shift highlights organ failure as a result of a dysregulated response of an organism to infection. Central to the new definition is the understanding that sepsis patients form a heterogeneous group and that the clinical picture requires alternative explanation patterns: e.g. sepsis is insufficiently explained by an overwhelming inflammatory response, it also comprises "immune paralysis" as another important pattern. Furthermore, severity of sepsis reflects the capacity of an organism to adapt and to mitigate the tissue damage through metabolic changes and repair mechanisms. Consistent with the paradigm of the new sepsis definition, adaptation in the presence of infections is crucial for the organism. Seriously injured or multiple trauma patients represent a patient group at particular risk, as sepsis often complicates the courses of these patients due to nosocomial infections. Along with comorbidities, past infections and age, leakage of skin and intestinal barriers as well as impaired defence and repair mechanism predispose trauma patients for a septic course. New pathophysiological insights suggest that the control of extracellular haem is of paramount significance. Haemolysis, transfusion and the consecutive expression of haem binding (such as haemopexin) or haem catabolic pathways (such as haem oxygenase) impair the ability of an organism to adapt, correlate with the prognosis and/or are strongly influenced by the surgical treatment concepts. Established treatment concepts of early causal and supportive therapy (damage control, antibiotic and fluid therapy) contribute to the reduction of mortality, depending on stringent implementation as part of Standard Operating Procedures (SOPs) and quality management. The paradigm shift in sepsis research offers an improved understanding of the underlying pathogenic factors within complex and heterogeneous patient groups, such as nosocomial sepsis following trauma. These novel approaches will allow developing new treatment strategies potentially contributing to a significant reduction in morbidity and mortality of trauma patients.Key messages1) According to the new paradigm, the ability to adapt to the pathogenic load associated with trauma and infection is crucial for an organism.2) Seriously injured or multiple trauma patients are predisposed for septic courses due to impaired adaptation mechanisms.3) Established treatment concepts of early causal and supportive therapy (damage control, antibiotic treatment, restrictive transfusion, and volume resuscitation) reduce mortality, in particular as part of SOPs and quality management strategies.4) Newly emerging treatment concepts that focus on the control of extracellular haem are promising, but require more evidence for translation into clinical practice., Competing Interests: The authors declare that they have no conflict of interest./Die Autoren geben an, dass kein Interessenkonflikt besteht., (Georg Thieme Verlag KG Stuttgart · New York.)

The International Health Regulations (IHR 2005) require all Member States to build and maintain the capacities to prevent, detect and respond to public health emergencies. Early detection of public health risks is one of the core functions. In order to improve surveillance and detection, a better understanding of the health system conditions and their influencing factors are needed. The Israeli Ministry of Health/IHR National Focal Point held a workshop to elucidate health system conditions and their influencing factors that enable earlier detection. The workshop methodology employed a stepwise, small working group analysis approach to elucidate the conditions and their influencing factors affecting each stage of recognition, assessment, and reporting of infectious disease outbreaks, at the local, regional and national levels. In order to detect public health risks earlier, the detection process needs to be moved closer to the local communities and start with building capacity within communities. Building capacity and engaging with local and diverse communities requires significant changes in the governance approach and include information sharing, multi-sectoral communication and coordination across various levels before, during and after public health emergencies. Across the regions, low-, mid- and high-income countries seem to struggle more with governance and information sharing rather than with technical capacities and capabilities., (Copyright © 2019 The Authors.

Overview: International activities to respond to the Ebola crisis in West Africa were mainly developed and focussed around the biomedical paradigm of Western health systems. This approach was often insensitive to societal perception, attitude, and behavioural determinants and clashed with community-based health traditions, narratives, and roles, e.g., of community health workers. In this peer-led capacity-building initiative, these deficiencies were identified and analysed. Innovative, more locally focussed, community-based solutions were articulated. The new approaches described put local people at the centre of all preparedness, response, and recovery strategies. This paradigm shift reframed the role of communities from victims to active managers of their response and reacknowledged the strength of community-based One Health. We conclude that strategies should aim at empowering, not just engaging, communities. Communities can improve short-term crisis management and build longer-term resilience and capacities that are much needed in the current global health climate., Background: The Ebola outbreak in West Africa, 2014-2016, was unprecedented in scale, extent, and duration. The international community was slow to step up its assistance in this global public health emergency and then faltered when its infection control management approaches clashed with West African realities [1]. Outbreak response evaluations have identified the need to better integrate social science intelligence [2], better collaborate with communities [3,4], more effectively draw on the strength of community health workers [5], and critically question the paradigm of Western health systems, which focus on imposing 'evidence-based' solutions that lack external validity in affected communities; i.e., they too often recommend actions that are inconsistent with, ignore, or violate traditional behaviours [6]. While there appears to be a consensus now on what needs to be done, how to achieve these goals remains a challenge.

Background: The threat posed by Meticillin-resistant Staphylococcus aureus (MRSA) has taken on an increasingly pan-European dimension. This article aims to provide an overview of the different approaches to the control of MRSA adopted in five European countries (Austria, Germany, Netherlands, Spain, and the UK) and discusses data and reporting mechanisms, regulations, guidelines, and health policy approaches with a focus on risk communication. Our hypothesis is that current infection control practices in different European countries are implicit messages that contribute to the health-related risk communication and subsequently to the public perception of risk posed by MRSA. A reporting template was used to systematically collect information from each country., Discussion: Large variation in approaches was observed between countries. However, there were a number of consistent themes relevant to the communication of key information regarding MRSA, including misleading messages, inconsistencies in content and application of published guidelines, and frictions between the official communication and their adoption on provider level., Summary: The variability of recommendations within, and across, countries could be contributing to the perception of inconsistency. Having inconsistent guidelines and practices in place may also be affecting the level at which recommended behaviors are adopted. The discrepancy between the official, explicit health messages around MRSA and the implicit messages stemming from the performance of infection control measures should, therefore, be a key target for those wishing to improve risk communication.

Background: The early detection of infectious disease outbreaks can reduce the ultimate size of the outbreak, with lower overall morbidity and mortality due to the disease. Numerous approaches to the earlier detection of outbreaks exist, and methods have been developed to measure progress on timeliness. Understanding why these surveillance approaches work and do not work will elucidate key drivers of early detection, and could guide interventions to achieve earlier detection. Without clarity about the conditions necessary for earlier detection and the factors influencing these, attempts to improve surveillance will be ad hoc and unsystematic., Methods: A systematic review was conducted using the PRISMA framework (Preferred Reporting Items for Systematic Reviews and Meta-analyses) to identify research published between January 1, 1990 and December 31, 2015 in the English language. The MEDLINE (PubMed) database was searched. Influencing factors were organized according to a generic five-step infectious disease detection model., Results: Five studies were identified and included in the review. These studies evaluated the effect of electronic-based reporting on detection timeliness, impact of laboratory agreements on timeliness, and barriers to notification by general practitioners. Findings were categorized as conditions necessary for earlier detection and factors that influence whether or not these conditions can be in place, and were organized according to the detection model. There is some evidence on reporting, no evidence on assessment, and speculation about local level recognition., Conclusion: Despite significant investment in early outbreak detection, there is very little evidence with respect to factors that influence earlier detection. More research is needed to guide intervention planning., (Copyright © 2016 The Author(s). Published by Elsevier Ltd.. All rights reserved.)

Biological risk management in public health focuses on the impact of outbreaks on health, the economy, and other systems and on ensuring biosafety and biosecurity. To address this broad range of risks, the International Health Regulations (IHR, 2005) request that all member states build defined core capacities, risk communication being one of them. While there is existing guidance on the communication process and on what health authorities need to consider to design risk communication strategies that meet the requirements on a governance level, little has been done on implementation because of a number of factors, including lack of resources (human, financial, and others) and systems to support effective and consistent capacity for risk communication. The international conference on "Risk communication strategies before, during and after public health emergencies" provided a platform to present current strategies, facilitate learning from recent outbreaks of infectious diseases, and discuss recommendations to inform risk communication strategy development. The discussion concluded with 4 key areas for improvement in risk communication: consider communication as a multidimensional process in risk communication, broaden the biomedical paradigm by integrating social science intelligence into epidemiologic risk assessments, strengthen multisectoral collaboration including with local organizations, and spearhead changes in organizations for better risk communication governance. National strategies should design risk communication to be proactive, participatory, and multisectoral, facilitating the connection between sectors and strengthening collaboration.

Risk communication has been identified as a core competence for guiding public health responses to infectious disease threats. The International Health Regulations (2005) call for all countries to build capacity and a comprehensive understanding of health risks before a public health emergency to allow systematic and coherent communication, response and management. Research studies indicate that while outbreak and crisis communication concepts and tools have long been on the agenda of public health officials, there is still a need to clarify and integrate risk communication concepts into more standardised practices and improve risk communication and health, particularly among disadvantaged populations. To address these challenges, the European Centre for Disease Prevention and Control (ECDC) convened a group of risk communication experts to review and integrate existing approaches and emerging concepts in the development of a training curriculum. This curriculum articulates a new approach in risk communication moving beyond information conveyance to knowledge- and relationship-building. In a pilot training this approach was reflected both in the topics addressed and in the methods applied. This article introduces the new conceptual approach to risk communication capacity building that emerged from this process, presents the pilot training approach developed, and shares the results of the course evaluation.

Background: Laboratory capacity building is characterized by a paradox between endemicity and resources: countries with high endemicity of pathogenic agents often have low and intermittent resources (water, electricity) and capacities (laboratories, trained staff, adequate regulations). Meanwhile, countries with low endemicity of pathogenic agents often have high-containment facilities with costly infrastructure and maintenance governed by regulations. The common practice of exporting high biocontainment facilities and standards is not sustainable and concerns about biosafety and biosecurity require careful consideration., Methods: A group at Chatham House developed a draft conceptual framework for safer, more secure, and sustainable laboratory capacity building., Results: The draft generic framework is guided by the phrase "LOCAL - PEOPLE - MAKE SENSE" that represents three major principles: capacity building according to local needs (local) with an emphasis on relationship and trust building (people) and continuous outcome and impact measurement (make sense)., Conclusion: This draft generic framework can serve as a blueprint for international policy decision-making on improving biosafety and biosecurity in laboratory capacity building, but requires more testing and detailing development.

Current risk assessment and risk communication of biosafety and biosecurity concerns lack a convenient metric and conceptual framework. The absence of such a systematic tool makes communication more difficult and can lead to ambiguous public perception of and response to laboratory biosafety incidents and biosecurity threats. A new 7-category scoring scale is proposed for incidents and situations in laboratories related to the handling of human and animal pathogens. The scale aims to help clarify risk categories, facilitate coordination and communication, and improve public understanding of risk related to biosafety and biosecurity.

Background: Health economics preference-based techniques, such as discrete choice experiments (DCEs), are often used to inform public health policy on patients' priorities when choosing health care. Although there is general evidence about patients' satisfaction with general-practice (GP) care in Europe, to our knowledge no comparisons are available that measure patients' preferences in different European countries, and use patients' priorities to propose policy changes., Methods: A DCE was designed and used to capture patients' preferences for GP care in Germany, England and Slovenia. In the three countries, 841 eligible patients were identified across nine GP practices. The DCE questions compared multiple health-care practices (including their 'current GP practice'), described by the following attributes: 'information' received from the GP, 'booking time', 'waiting time' in the GP practice, 'listened to', as well as being able to receive the 'best care' available for their condition. Results were compared across countries looking at the attributes' importance and rankings, patients' willingness-to-wait for unit changes to the attributes' levels and changes in policy., Results: A total of 692 respondents (75% response rate) returned questionnaires suitable for analysis. In England and Slovenia, patients were satisfied with their 'current practice', but they valued changes to alternative practices. All attributes influenced decision-making, and 'best care' or 'information' were more valued than others. In Germany, almost all respondents constantly preferred their 'current practice', and other factors did not change their preference., Conclusion: European patients have strong preference for their 'status quo', but alternative GP practices could compensate for it and offer more valued care., (© The Author 2014.

Objective: Risk communication plays a central role in the management of infectious disease. The World Health Organization's 2005 International Health Regulations have highlighted the need for countries to strengthen their capacities in this area to ensure effective responses to public health emergencies. We surveyed laboratories, hospitals, and public health institutions in Germany to detail the current situation regarding risk communication and crisis management and to identify which areas require further development., Methods: A mixed methods approach was adopted. An initial questionnaire was distributed to relevant persons in laboratories and hospitals, and semistructured interviews were conducted with selected participants. Representatives from state public health authorities, federal agencies, and media also were interviewed to add additional contextual information to the questionnaire responses., Results: Based on the responses received, the universal sense among key stakeholders was that risk communication and crisis communication measures must be improved. Collaborative working was a consistent theme, with participants suggesting that a partnering strategy could help to improve performance. This approach could be achieved through better coordination between groups, for example, through a knowledge-sharing policy., Conclusions: More research is needed on how such collaboration might be implemented, along with a general conceptual framework for risk communication to underpin the overall strategy.

A bioterrorist attack may result in a large number of people who have not been exposed coming to medical facilities in search of treatment or reassurance. In this article, we review evidence from 3 previous biological incidents that are analogous to a bioterrorist attack in order to gauge the likely incidence of such "low-risk patients" and to identify possible strategies for coping with this phenomenon. Evidence from the anthrax attacks in the United States suggested that a surge of low-risk patients is by no means inevitable. Data from the SARS outbreak illustrated that if hospitals are seen as sources of contagion, many patients with non-bioterrorism-related healthcare needs may delay seeking help. Finally, the events surrounding the pneumonic plague outbreak of 1994 in Surat, India, highlighted the need for the public to be kept adequately informed about an incident. Although it is impossible to say what the likely incidence of low-risk patients will be during a future bioterrorist incident, several strategies may help to reduce it and to safeguard the well-being of the low-risk patients themselves. These strategies include providing clear information about who should and should not attend hospital; using telephone services to provide more detailed information and initial screening; employing rapid triage at hospital entrances, based, where possible, on exposure history and objective signs of illness; and following up by telephone those judged to be at low risk.

The term pandemic refers to an international or worldwide outbreak of an infectious disease which is limited in time. Due to their high infectiousness and easy person-to-person transmission, flu viruses repeatedly lead to pandemics (approx. 3 pandemics per century.). In contrast to an epidemic, a pandemic is not restricted to one area. The mortality of an influenza pandemic is greater than the seasonal flu wave, and is not restricted to the classical risk groups: high rates of infection can occur in all age groups, with peaks frequently occurring amongst young adults.The specific virological characteristics of the influenza virus represent a great challenge for the health system. In principle, any influenza virus which has never before - or at least not for a long time - circulated within the population can develop into a pandemic virus. One possible candidate amongst others appears to be the influenza virus A-H5N1. Influenza pandemics usually occur at intervals of 11 to 39 years, and 30 years have now passed since the last pandemic. At the moment, the national and international pandemic plans have in most cases not yet been completely worked out. The co-operation between the individual countries should be intensified, and in Germany in particular, efforts should be made - in view of the different concepts of the individual federal states - to arrive at a uniform action plan.The consequences of a pandemic affect both the economic and the social sphere. Hospitals, practicing doctors and public health services must jointly develop action plans in order to be able to care for large numbers of patients within a very short time. Occupational medical specialists should form a link between health services, companies and doctors and hospitals, and already be developing plans and their communication for the companies under their care., (© Springer 2007.)
