Purpose Signs saturate and surround society. This article illuminates the significant roles played by documentation within the context of the coronavirus pandemic. It centres, what it terms as, “COVID-19 signage” as essential extensions of nonpharmaceutical interventions (NPIs) into society. It posits that this signage helps materialize, mediate and articulate the pandemic from an unseen phenomenon into tangible objects with which people see and interact. Design/methodology/approach This article presents a documentary typology of COVID-19 signage to provide a conceptual framework in which to situate, approach and analyse this diverse documentation and its implications for social life and traffic. Further, this article offers a case study of Malta's COVID-19 signage that helped materialize, mediate and articulate the pandemic across the European island nation during its national lockdown in the first half of 2020. This case study helps contextualize these signs and serves as a dual contemporary and historical overview of their creation, implementation and use. Findings The coronavirus pandemic cannot be seen with the naked eye. It is, in many respects, an abstraction. Documents enable the virus to be seen and the pandemic to be an experienced reality. Specifically, COVID-19 signage materializes the disease and pandemic into tangible items that individuals interact with and see on a daily basis as they navigate society. From personal to environmental to community signs, these documents have come to mediate social life and articulate COVID-19 during this extraordinary health crisis. A material basis of a shared “pandemic social culture” is consequently established by and through this signage and its ubiquity. Research limitations/implications This article can serve as a point of departure for analyses of other kinds of COVID-19 signage in various contexts. It can serve as an anchor or example for other investigations into what other signs were used, including why, when and how they were produced, designed, formatted, implemented, enforced, altered and/or removed. For instance, it could be used for comparative studies between different NPIs and their associated signage, or of the signage appearing between different cities or countries or even the differences in signage at various political and socio-temporal points of the pandemic. Social implications It is dually hoped that this article's documentary typology, and historical snapshot, of COVID-19 signage could help inform how current and future NPIs into society are or can be used to mitigate the coronavirus or other potential health crises as well as serve as both a contemporary and historical snapshot of some of the immediate and early responses to the pandemic. Originality/value This documentary typology can be applied to approaches and analyses of other kinds of COVID-19 signage and related documentation. By serving as a conceptual framework in which situate, approach and analyse these documents, it is hoped that this article can help create a sense of clarity in reflections on sign-saturated environments as well as be practically employed for examining and understanding the effective implementation of NPIs in this pandemic and other health crises.
