‘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.

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.

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.

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.

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 onset of the COVID-19 pandemic has highlighted the criticality of science communication. Utilising a mixed-methods approach, this article takes an audience-focused perspective to analysing COVID-19 related social media posts on 23 popular South Pacific community Facebook pages over a four-month period across eight South Pacific countries. We analyse how audiences co-opt scientific terms, address information gaps and embed it in their lived experience. It is ascertained that online conversations around COVID-19 in the Pacific are intermeshed with both scientific fact and, personal accounts and rumours, referred to locally as ‘coconut wireless’, problematising established modes of empirical enquiry.

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.

Based on recent accounts of the sociology of expertise, we analyse the public contestation and expansion of expertise in the context of COVID-19. During the epidemic, the expertise of the Finnish Institute for Health and Welfare (THL), became increasingly contested. By exploring Twitter discussions concerning the actions of THL during the first months of the epidemic from January to mid-June 2020, we analyse the main motivations and arguments in this public contestation as well as the alternative forms of expertise proposed by the critics. We focus particularly on two forms of criticism arguing for what we call networked expertise: liberal crowdsourcing supporters and data-solutionists presenting alternative epidemiological models.
