In this article, we analysed the 100 most engaging contents about COVID-19 on social networks in Brazil, in March 2020, when the disease officially arrived in the country. Within the infodemic context, we analysed the accuracy of the information and the reliability of the websites that guided the debate. Our results show that misinformation/disinformation accounted for 13.5% of the sample and that their average engagement was greater than the one for the information that could be verified in other sources and in accordance with scientific evidence. We also found that professional websites, especially journalistic ones, predominate among sources. The results point to the need to combine science communication strategies with network communication dynamics.

This commentary uses a case study of Uganda and the country's attempts to adopt genetically modified organisms (GMOs) to demonstrate how activists have become communicators of scientific knowledge in the digital age. The digital age allows activists to share their information and collaborate with those who can push their agenda. I argue that anti-GMO activists have positioned themselves as influencers in a debate where weight-of-scientific evidence seems to have been overshadowed by perceptions, largely driven by socio-democratic considerations that require participation in technological uptake.

This paper analyzes a new initiative in Brazil’s ‘Ciência Hoje’ magazine, called “Interactive Articles”, aimed at understanding how stakeholders relate to interactivity when writing a science communication article. We investigated participation in two platforms (magazine website and Facebook page) and interviewed the authors concerning the tool’s impact on their articles. Comments were examined using intensity analysis and content analysis, while interviews were analyzed with the collective subject discourse method. The study concluded that the novel initiative presented positive results in terms of interactivity and was regarded as public engagement and contextual model of science communication from the interviewed authors.

‘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.

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.

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.

This paper offers an ethnographic account of the editorial response to the COVID-19 outbreak by the Science Media Center Germany. Ethnographic research data was gathered during a 4-week fieldstay in January 2020 which coincided with the first weeks of the COVID-19 outbreak. The findings offer insights into how the editorial staff grappled with the scientific non-knowledge and uncertainty that marked the initial phase of the global COVID-19 outbreak, while simultaneously dealing with acute journalistic demands for expertise.

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 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.
