Studying the introduction and spread of SARS-CoV-2

Trends in SARS-CoV-2 caseload and spread are often reported on large geographic scales, such as US states, which obscures the degree to which trends may differ on smaller geographic scales. In a recent Nature Communications paper, Pathology faculty Shelby and Dave O’Connor, Bill Rehrauer and colleagues use deeply sampled SARS-CoV-2 sequence data to characterize spread in southeastern Wisconsin and, more importantly, to illustrate distinct patterns of spatiotemporal SARS-CoV-2 spread in two very nearby communities – Dane and Milwaukee Counties. Their data also show reduced viral spread in both counties during the statewide “Safer at Home” order.
