The devastating effects of COVID-19 and the speed of both the scientific and medical response and the public information requirements about frontline healthcare work, medical advances and policy and compliance measures has necessitated an intensity of science communication never seen before. This JCOM special issue — the first of two parts — looks at the challenges of communicating COVID-19 and coronavirus in the early spread of the disease in 2020. Here we present papers from across the world that demonstrate the scale of this challenge.

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.

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.

Today, thanks to the consolidation of Internet, users have access to many sources of information on health issues. On social networks, there are profiles of health professionals who share content that generates credibility when published by specialists who are knowledgeable in the sector. These profiles include pharmaceutical professionals who disseminate and create content based on scientific knowledge. Pharmaceutical influencers on Instagram have an informative role on health, nutrition and cosmetic dermatology issues. This research aims to learn about the communication management of these influencers during the Coronavirus crisis in Spain and how they have modified their habitual discourse, as well as seeking to identify the formats of their publications that generate greater engagement and conversions among their followers.

The nationwide shortage of PPE for health care workers has been well documented. Reporting on this issue has been complicated by hospitals' imposition of gag orders on physicians and health care workers. There are harms that result from imposing these gag orders that go beyond the obvious harms to public and employee health and safety. Using Hirschman's ‘Exit, Voice, and Loyalty’ (1970) as a framework demonstrates that these orders represent a dangerous concentration of power in employer hands — health care workers are reduced to functionaries. Hirschman's argument, in part, is that organisations should seek to balance the availability of exit, voice, and loyalty for employees. Restricting employee options in morally untenable situations to exit only leads to direct and indirect harms. These gag orders are a pernicious practice, and bring with them long-term negative implications for employee morale, employee effectiveness, and public service.

The emergence of COVID-19 represented a critical problem for the legitimacy and prestige of the Chinese Communist Party. The Chinese authorities had to fight not only to contain the spread of the virus but also to create a favorable public opinion about how they managed the crisis. Based on Foucault's approach to the “Regime of Truth”, this article analyzes the narrative surrounding the origin of the virus and how science was employed to lend it legitimacy. The article concludes by reviewing how the idea of science as a truth knowledge is used to construct a particular viewpoint, one focused on legitimizing the outbreak containment measures taken by the Chinese government.

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.

The novel coronavirus (COVID-19) which was first reported in China's Wuhan province in December 2019 became a global pandemic within a few months. The exponential rise in COVID-19 cases globally was accompanied by a spike in misinformation about the pandemic, particularly on social media. Employing Social Network Theory as a lens, this qualitative study explores how selected international celebrities appropriated their Twitter micro-blogging pages to announce their COVID-19 infection to the world. The study finds that these celebrities can take advantage of their huge social media following to counter disinfodemic and promote awareness about health pandemics.

‘Coronavirus Disease 2019 (COVID-19)’ is the neologism coined in reference to the pandemic disease currently affecting countries worldwide. The World Health Organization (WHO) was the international entity that coined this neologism in all its official languages, Arabic amongst them. However, in mass media, the most commonly used term is ‘coronavirus’, which is a meronymic denomination. This corpus-based case study aims at giving new insights into the creation of these neologisms in English and their equivalents in Arabic, and to the adequacy of the meronymic use of the term ‘coronavirus’ in the English and Arabic mass media.

This article seeks to address the lack of sociocultural diversity in the field of science communication by broadening conceptions of citizen science to include citizen social science. Developing citizen social science as a concept and set of practices can increase the diversity of publics who engage in science communication endeavors if citizen social science explicitly aims at addressing social justice issues. First, I situate citizen social science within the histories of citizen science and participatory action research to demonstrate how the three approaches are compatible. Next, I outline the tenets of citizen social science as they are informed by citizen science and participatory action research goals. I then use these tenets as criteria to evaluate the extent to which my case study, a community-based research project called ‘Rustbelt Theater’, counts as a citizen social science project.
