This study mainly explores the communication preferences of the public; their level of trust in the government; and the factors affecting their risk/crisis perception amidst the COVID-19 pandemic. The key findings —derived from the data collected through an online survey and analysis using descriptive statistics, cross-tabulations, and Structural Equation Modeling (SEM), provide insights on how Local Government Units (LGUs) can improve their risk/crisis communication in this current health crisis. Among the key takeaways include the use of social media platforms, like Facebook, and native/local language for effective risk/crisis communication which may, consequently, foster trust building between the LGUs and the public.

The study examines the effect of COVID-19 on the fact-checking resources in Tunisia. Through developing monographies, we traced the trajectory of most fact-checking platforms in the Tunisian media and explored their teams and working strategies. We noticed a clear spike in the creation of fact-checking platforms during and after February 2020 and determined that the pandemic created a context in which these platforms emerged and flourished. However, many of these platforms, were a product of journalists' individual initiatives and lacked a clear editorial and strategic inclusion of fact-checking. Besides, we found a lack of prior training and an absence of fact-checkers specialized in science and health communication.

The COVID-19 pandemic has impacted the world in ways not seen since the 1918–1920 Spanish Flu. Disinformation campaigns targeting health crisis communication during this pandemic seek to cripple the medical response to the novel coronavirus and instrumentalize the pandemic for political purposes. Propaganda from Russia and other factions is increasingly infiltrating public and social media in Ukraine. Still, scientific literature has only a limited amount of evidence of hybrid attacks and disinformation campaigns focusing on COVID-19 in Ukraine. We conducted a review to retrospectively examine reports of disinformation surrounding health crisis communication in Ukraine during the COVID-19 response. Based on the themes that emerged in the literature, our recommendations are twofold: 1) increase transparency with verified health crisis messaging and, 2) address the leadership gap in reliable regional information about COVID-19 resources and support in Ukraine.

COVID-19 pandemic hit Brazil in February 2020. Controversial information, minimization of the problem, and difficulties resulting from extreme social inequality, led to the intensification of the disease and number of deaths. During this period, the government failed to provide information to the Deaf minority that uses Brazilian Sign Language to communicate. This study analyzes information provided by a TV with accessibility, as well as a Facebook page created by Deaf and hearing interpreters, and videos posted on Instagram and YouTube for that community. The novelty of the subject required linguistic efforts so that information could be coherent in sign language.

Understanding how individuals perceive the barriers and benefits of precautionary actions is key for effective communication about public health crises, such as the COVID-19 outbreak. This study used innovative computational methods to analyze 30,000 open-ended responses from a large-scale survey to track how Wisconsin (U.S.A.) residents' perceptions of the benefits of and barriers to performing social distancing evolved over a critical time period (March 19th to April 1st, 2020). Initially, the main barrier was practical related, however, individuals later perceived more multifaceted barriers to social distancing. Communication about COVID-19 should be dynamic and evolve to address people's experiences and needs overtime.

A global crisis such as the COVID-19 pandemic that started in early 2020 poses significant challenges for how research is conducted and communicated. We present four case studies from the perspective of an interdisciplinary research institution that switched to “corona-mode” during the first two months of the crisis, focussing all its capacities on COVID-19-related issues, communicating to the public directly and via media, as well as actively advising the national government. The case studies highlight the challenges posed by the increased time pressure, high demand for transparency, and communication of complexity and uncertainty. The article gives insights into how these challenges were addressed in our research institution and how science communication in general can be managed during a crisis.

Despite Australian horse owners being encouraged to vaccinate their horses against Hendra virus to reduce the risk of this potentially fatal virus to horses and humans, vaccine uptake has been slow. Discourse around the vaccine has been characterised by polarisation and dissenting voices. In this study we interviewed horse owners (N=15) and veterinarians (N=10), revealing how expert knowledge, disqualification of lay knowledge and inadequate handling of uncertainty impacted divisive discourse around Hendra virus. We assert that more inclusive, reflective and ultimately more effective risk communication practices will result if the legitimacy of diverse knowledge sources and the inevitability of uncertainty are acknowledged.

This theoretical paper proposes a framework for how citizen science can be adapted to organizational contexts. Using an “input, process, output” approach, this model proposes organizational factors (e.g., communication channels and styles, and organizational structure) that should be considered when choosing among citizen science approaches (e.g., contributory, collaborative, co-created). The essay identifies possible outcomes for the individual, organization, and larger sector from employing a citizen science approach within an organizational setting.

Verbal probability phrases are often used in science communication to express estimated risks in words instead of numbers. In this study we look at how laypeople and statisticians interpret Dutch probability phrases that are regularly used in news articles. We found that there is a large variability in interpretations, even if the phrases are given in a neutral context. Also, statisticians do not agree on the interpretation of the phrases. We conclude that science communicators should be careful in using verbal probability expressions.

Public acceptance of vaccination and Genetically Modified (GM) food is low and opposition is stiff. During two science festivals in France, we discussed in small groups the scientific evidence and current consensus on the benefits of vaccination and GM food safety. Our interventions reinforced people's positive opinions on vaccination and produced a drastic positive shift of GM food opinions. Despite the controversial nature of the topics discussed, there were very few cases of backfire effects among the 175 participants who volunteered. These results should encourage scientists to engage more often with the public during science festivals, even on heated topics.
