Experts, news media, and social media commentators struggled to make sense of SARS-CoV-2 January–May 2020 as disease caused by this virus, COVID-19, circulated the globe. This paper represents a longitudinal analysis of the primary narratives produced across expert, media, and social media sources to describe the virus, its phylogenetic origins, and biological effects. High expert uncertainty coupled with amplifying representations of risk across time drove collective sensemaking and conspiratorial narratives.
