Ex ante knowledge for infectious disease outbreaks:Introducing the organizational network governance approach

The core question addressed is to what extent ex ante knowledge can be made available from a network governance perspective to deal with a crisis such as an infectious disease outbreak. Such outbreaks are often characterized by a lack of information and knowledge, changing and unforeseen conditions as well as a myriad of organizations becoming involved on the one hand but also organizations which do not become adequately involved. We introduce the organizational network governance approach as an exploratory approach to produce useful ex ante information for limiting the transmission of a virus and its impact. We illustrate the usefulness of our approach introducing two fictitious but realistic outbreak scenarios: the West Nile Virus (WNV), which is transmitted via mosquitos and the outbreak of a New Asian Coronavirus (NAC) which is characterized by human to human transmission. Both viruses can lead to serious illnesses or even death as well as large health care and economic costs. Our organizational network governance approach turns out to be effective in generating information to produce recommendations for strengthening the organizational context in order to limit the transmission of a virus and its impact. We also suggest how the organizational network governance approach could be further develope

Getting ready to act:Theorising a stepwise transition into crisis response at points of entry based on interviews with COVID-19 responders and a military preparedness framework

Introduction: Points of entry (POE) have an important role in timely national response to infectious diseases threats. However, a guiding framework is lacking for the transition from generic preparedness into optimally specified response for an imminent infectious disease threat, a step called ‘operational readiness’. Objective: We aim to contribute to the conceptual closure of this preparedness–response gap for infectious disease control at POE by providing content to the operational readiness concept. Design: We first explored the NATO Combat Readiness (NCR) concept for its applicability on infectious disease control at POE, as the military discipline faces the same need of being flexible in preparing for unknown threats. Concepts of the NCR that support the transition into response to a specific threat were integrated into the operational readiness concept. To explore the added value of the concept in practice, we conducted and analysed semistructured interviews of professionals at European POE (n=24) responsible for the early COVID-19 response. Results: Based on the NCR, operational readiness builds on the fact that activating the response capabilities and capacities to a specific threat requires time. For professionals at POE, the transition from generic preparedness into the COVID-19 response led to challenges in specifying response plans, dealing with an overload of information, while experiencing shortages of public health staff. These challenges could be covered within operational readiness by defining the time and the specific staging needed to upgrade response capabilities and capacities. Discussion: We conclude that a guiding framework for operational readiness seems appropriate in relation to the many activities and challenges POE have had to face during the COVID-19 response. Operational readiness is mainly defined by the time dimension required to deploy the response to a specific threat. However, integrating this conceptual framework into practice requires structural and sustainable investments in outbreak preparedness

How prepared are we for cross-border outbreaks? An exploratory analysis of cross-border response networks for outbreaks of multidrug resistant microorganisms in the Netherlands and Germany

Background: The emergence and spread of multidrug resistant microorganisms is a serious threat to transnational public health. Therefore, it is vital that cross-border outbreak response systems are constantly prepared for fast, rigorous, and efficient response. This research aims to improve transnational collaboration by identifying, visualizing, and exploring two cross-border response networks that are likely to unfold during outbreaks involving the Netherlands and Germany.Methods: Quantitative methods were used to explore response networks during a cross-border outbreak of carbapenem resistant Enterobacteriaceae in healthcare settings. Eighty-six Dutch and German health professionals reflected on a fictive but realistic outbreak scenario (response rate ≈ 70%). Data were collected regarding collaborative relationships between stakeholders during outbreak response, prior working relationships, and trust in the networks. Network analysis techniques were used to analyze the networks on the network level (density, centralization, clique structures, and similarity of tie constellations between two networks) and node level (brokerage measures and degree centrality).Results: Although stakeholders mainly collaborate with stakeholders belonging to the same country, transnational collaboration is present in a centralized manner. Integration of the network is reached, since several actors are beneficially positioned to coordinate transnational collaboration. However, levels of trust are moderately low and prior-existing cross-border working relationships are sparse.Conclusion: Given the explored network characteristics, we conclude that the system has a promising basis to achieve effective coordination. However, future research has to determine what kind of network governance form might be most effective and efficient in coordinating the necessary cross-border response activity. Furthermore, networks identified in this study are not only crucial in times of outbreak containment, but should also be fostered in times of non-crisis

Public knowledge and Preventive Behavior During a Large-Scale Salmonella Outbreak: Results from an Online Survey in the Netherlands

Background Food-borne Salmonella infections are a worldwide concern. During a large-scale outbreak, it is important that the public follows preventive advice. To increase compliance, insight in how the public gathers its knowledge and which factors determine whether or not an individual complies with preventive advice is crucial. Methods In 2012, contaminated salmon caused a large Salmonella Thompson outbreak in the Netherlands. During the outbreak, we conducted an online survey (n = 1,057) to assess the general public’s perceptions, knowledge, preventive behavior and sources of information. Results Respondents perceived Salmonella infections and the 2012 outbreak as severe (m = 4.21; five-point scale with 5 as severe). Their knowledge regarding common food sources, the incubation period and regular treatment of Salmonella (gastro-enteritis) was relatively low (e.g., only 28.7% knew that Salmonella is not normally treated with antibiotics). Preventive behavior differed widely, and the majority (64.7%) did not check for contaminated salmon at home. Most information about the outbreak was gathered through traditional media and news and newspaper websites. This was mostly determined by time spent on the medium. Social media played a marginal role. Wikipedia seemed a potentially important source of information. Conclusions To persuade the public to take preventive actions, public health organizations should deliver their message primarily through mass media. Wikipedia seems a promising instrument for educating the public about food-borne Salmonell

Wat weten Nederlanders van salmonella en welke maatregelen nemen ze tijdens een uitbraak?

Voedselgerelateerde Salmonella-infecties zijn een wereldwijd probleem. Gedurende een grootschalige uitbraak is het van belang dat het publiek de maatregelen neemt die door de GGD’en en de overheid worden geadviseerd. Om de naleving van deze maatregelen te vergoten, is het essentieel om inzicht te hebben in hoe en waar het publiek informatie vergaart en welke factoren bepalen of zij wel of niet de geadviseerde maatregelen neemt. Uit dit onderzoek blijkt dat GGD’en en overheid tijdens een uitbraak hun boodschap het beste via massamedia kunnen verspreiden. Wikipedia lijkt een veelbelovend kanaal om het publiek kennis bij te brengen over Salmonella

Coverage of the 2011 Q fever vaccination campaign in the Netherlands, using retrospective population-based prevalence estimation of cardiovascular risk-conditions for chronic Q fever

Background: In 2011, a unique Q fever vaccination campaign targeted people at risk for chronic Q fever in the southeast of the Netherlands. General practitioners referred patients with defined cardiovascular risk-conditions (age >15 years). Prevalence rates of those risk-conditions were lacking, standing in the way of adequate planning and coverage estimation. We aimed to obtain prevalence rates retrospectively in order to estimate coverage of the Q fever vaccination campaign. Methods: With broad search terms for these predefined risk-conditions, we extracted patient-records from a large longitudinal general-practice research-database in the Netherlands (IPCI-database).

Development and validation of the MosquitoWise survey to assess perceptions towards mosquitoes and mosquito-borne viruses in Europe

Due to climate change and the expanding geographical ranges of key mosquito species, several mosquito-borne viruses (MBVs) have recently emerged in Europe. Understanding people’s perceptions and behaviours towards these viruses and the mosquitoes capable of transmitting them is crucial for implementing effective prevention measures and targeted communication campaigns. However, there is currently no appropriate validated survey for European populations to assess this. This study developed and validated a standardized survey, based on the Health Belief Model (HBM), to assess perceptions of mosquitoes and MBVs among Europe’s residents. The survey was distributed online to United Kingdom (UK), Dutch and Spanish participants through panel providers. Survey validity and reliability were tested using confirmatory factor analysis (CFA) and Cronbach’s alpha. The optimised survey was completed by 336 UK, 438 Dutch and 475 Spanish residents, respectively, and the HBM items passed our validity and reliability testing in all three countries. The final survey has 57 questions, including 19 validated HBM items, and questions to assess demographic characteristics, knowledge, prevention measures and behavioural determinants. Our MosquitoWise survey bridges researchers' understandings of European residents’ perceptions and knowledge as a first step to improve preventive behaviour towards mosquitoes and MBVs and guide prevention and communication initiatives.</p
