The latest in a growing number of edited volumes that take science communication as a phenomenon to be explored through science cultures is a rich book full of theoretical and methodological rigour. There are 17 chapters included here from 33 authors across 16 different countries containing selected paper contributions from the 2018 Science & You conference in Beijing jointly organised by the Chinese National Academy of Innovation Strategy and the University of Lorraine, France. With an opening address by Massimiano Bucchi, chapters are arranged thematically, with emphasis on the roles of institutions, state and media in the social dynamics and public understandings of science and technology across global cultures.

Since early 2020, communicating risks associated with COVID-19 and providing safety advice have been top priorities for health agencies and governments. With an increase in employees working remotely following the global spread of coronavirus coupled with increasingly sophisticated marketing strategies, global brands unsurprisingly engaged consumers and publics by acknowledging the crisis that engulfed the world. An increase in online marketing was observed in an already existing trend online where hybrids of consumer, brand and product-as-object interacted as equals, using contemporary informal codes of social media discourse and often using irony and humour. However, this paper critically assesses how such important communication responsibilities about coronavirus were taken up by private companies. Online and social media outputs were analysed through a lens of anthropomorphising and posthuman brands. A typology of brand strategies was developed based on engagement and how COVID-19 science, care and prevention were communicated. The paper concludes with a reflection on where this may lead health and environmental communication and what it means for science communicators.

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.

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.
