Simulating influenza pandemic dynamics with public risk communication and individual responsive behavior

Fight COVID Milwaukee protective behaviors and risk communications associated with the COVID-19 pandemic

The COVID-19 pandemic has had a major impact on society, causing significant disruptions to everyday life. Risk communication strategies can play an important role in risk management as they allow individuals to prepare for and respond to public health emergencies appropriately. The aim of this study is to investigate public risk behaviors, perceptions of risk and risk communication, and experiences with COVID-19 to better understand the impact of COVID-19 on our community and to better inform public health decisions about communicating and reducing personal risk. Nine virtual focus groups were conducted with 79 residents of Milwaukee County. Audio transcripts of focus group recordings were qualitatively analyzed using MAXQDA. Predominant themes identified include public risk protective behaviors, the emotional toll associated with lockdown measures, and risk communication. Our findings provide a better understanding of how adults, African American and Hispanic groups in particular, viewed the risk communications and protective behaviors associated with COVID-19, how their lives were impacted by the pandemic, and how to effectively communicate public information about personal risk. These findings can help guide risk communication efforts and public health policy interventions for potential infection outbreaks in the future.

How reported outbreak data can shape individual behavior in a social world

Agencies reporting on disease outbreaks face many choices about what to report and the scale of its dissemination. Reporting impacts an epidemic by influencing individual decisions directly, and the social network in which they are made. We simulated a dynamic multiplex network model-with coupled infection and communication layers-to examine behavioral impacts from the nature and scale of epidemiological information reporting. We explored how adherence to protective behaviors (social distancing) can be facilitated through epidemiological reporting, social construction of perceived risk, and local monitoring of direct connections, but eroded via social reassurance. We varied reported information (total active cases, daily new cases, hospitalizations, hospital capacity exceeded, or deaths) at one of two scales (population level or community level). Total active and new case reporting at the population level were the most effective approaches, relative to the other reporting approaches. Case reporting, which synergizes with test-trace-and-isolate and vaccination policies, should remain a priority throughout an epidemic.

Factors influencing the protective behavior of individuals during COVID-19: a transnational survey

To slow the spread of infectious disease, it is crucial to understand the engagement of protective behavior among individuals. The purpose of this study was to systematically examine individuals' protective behaviors and the associated factors across countries during COVID-19. This causal-comparative study used a self-developed online survey to assess individuals' level of engagement with six protective behaviors. Analysis of variance and McNemar's test were employed for data analysis. Three hundred and eighty-four responses were analyzed. The majority of participants lived in three areas: Taiwan, Japan, and North America. Overall, the participants reported a high level of engagement in protective behaviors. However, engagement levels varied according to several demographic variables. Hand hygiene and cleaning/ventilation are two independent behaviors that differ from almost all other protective behaviors. There is a need to target the population at risk, which demonstrates low compliance. Different strategies are needed to promote specific protective behaviors.

Rapid review of virus risk communication interventions: Directions for COVID-19

OBJECTIVE

In response to COVID-19, we conducted a rapid review of risk communication interventions to mitigate risk from viruses to determine if such interventions are efficacious.

METHODS

We searched for risk communication interventions in four databases: Medline, PsycInfo, the ProQuest Coronavirus Research Database, and CENTRAL. The search produced 1572 articles. Thirty-one articles were included in the final review.

RESULTS

Results showed risk communication interventions can produce cognitive and behavior changes around viruses. Results were more consistently positive for interventions focused on HIV/AIDS as compared to influenza. There was no consistent best intervention approach when comparing peer health, audio/visual, and intensive multi-media interventions. Tailoring risk communication toward a target population, in comparison to not tailoring, was related to better outcomes.

CONCLUSION

The results suggest that risk communication interventions can be efficacious at reducing risk from viruses. They also highlight the complexity of risk communication interventions. Additional research is needed to understand the mechanisms that lead risk communication to reduce risk from viruses.

PRACTICAL VALUE

Results support risk communication interventions to reduce risk from viruses.

Reflecting on the safety zoo: Developing an integrated pandemics barrier model using early lessons from the Covid-19 pandemic

Our current predicament, the Covid-19 pandemic is first of all a health crisis. However, social disruption and economic damage are becoming visible some 7 months after the Wuhan City outbreak early December 2019. The authors wondered what could have been done better in prevention and repression of the Covid-19 pandemic from a safety management and risk control point of view. Within a case study framework, the authors gathered literature on pandemics, about country response effectiveness, and about human behaviour in the face of danger. The results consist of a safety management oriented narrative about the current pandemic, several critical observations about the current paradigms and shortcomings of preparation, and a number of opportunities for improvements of countermeasures. Many of the proverbial animals in the safety zoo, representing typical behaviours, were observed in action. Based on well proven risk analysis methods - risk management, event tree, scenarios, bowtie - the authors then analyse the generic sequence of events in a pandemic, starting from root causes, through prevention, via the outbreak of a pathogen, through mitigation to long term effects. Based on this analysis the authors propose an integrated pandemics barrier model. In this model the core is a generic pandemic scenario that is distinguishing five risk controllable sequential steps before an outbreak. The authors contend that the prevention of pandemics via safety management based biohazard risk control is both possible and of paramount importance since it can stop pandemic scenarios altogether even before an outbreak.
