On February 11, 2020, the World Health Organization announced the name of a new disease, COVID-19. As the virus that causes the disease spread across the globe, the world went into crisis mode. The various actors of the COVID-19 crisis include, in part, politicians, scientists, health experts, citizens, journalists, front line workers, first responders, organizations, and so on. Their voices and their related communicative processes play out in the rhetorical arena that emerges from the crisis. Crisis memes are a particularly intriguing and salient part of the COVID-19 public discourse. Combining the theoretical implications of rhetorical arena theory (RAT) with multimodality and its close ties to social semiotics, this paper will analyze the unique nature of memes created during the cycle of a crisis.

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 study explores how South African newspaper cartoonists portrayed the novel coronavirus during the initial months of the COVID-19 pandemic. We show how these cartoons respond to the socio-economic and cultural contexts in the country. Our analysis of how cartoonists represent the novel coronavirus explain how they create meaning (and may influence public sentiments) using colour, morphological characteristics and anthropomorphism as visual rhetorical tools. From a total population of 497 COVID-19-related cartoons published in 15 print and online newspapers from 1 January to 31 May 2020, almost a quarter (24%; n=120) included an illustration of the coronavirus. Viruses were typically coloured green or red and attributed with human characteristics (most often evil-looking facial expressions) and with exaggerated, spikey stalks surrounding the virus body. Anthropomorphism was present in more than half of the 120 cartoons where the virus was illustrated (58%; n=70), while fear was the dominant emotional tone of the cartoons. Based on our analysis, we argue that editorial cartoons provide a useful source to help us understand the broader discursive context within which public communication of science operates during a pandemic.

This research aimed to analyze the quality of the information conveyed through YouTube videos in Portuguese on the use of two medicines suggested for the treatment of COVID-19: chloroquine and hydroxychloroquine. The ‘Brief DISCERN’ questionnaire was applied to assess the quality of the video content as well as baseline characteristics, such as length, views, likes and dislikes, in a total of 90 videos with almost 4,5 million views. Traditional media accounted for 58,89% of videos. Misleading information was present in most of the videos (63,5%). Despite the ease of access, the videos showed problems in the quality of information.

As COVID-19 continues its devastating pathway across the world, in this second part of the JCOM special issue on communicating COVID-19 and coronavirus we present further research papers and practice insights from across the world that look at specific national challenges, the issue of “fake news” and the possibilities of satire and humour in communicating the seriousness of the deadly disease.

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.

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 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.

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.
