a, The number of weekly COVID-19 cases in humans from October 2020 to September 2021 in Ohio. Shading indicates the proportion of viruses sequenced each week in Ohio that belong to one of five Pango lineages (or ‘other’). b, Summary of six human-to-deer transmission events observed in Ohio, with putative deer-to-deer transmission. c, Maximum-likelihood tree inferred for SARS-CoV-2 viruses in humans and white-tailed deer in Ohio during January to March 2021. Tips are shaded by Pango lineage and major lineages are boxed, labelled and shaded similar to Fig. 2b. Viruses found in white-tailed deer (clusters or singletons) are shaded red and labelled by location (the B.1.2 virus identified at site 4 is not shown owing to lower sequence coverage). All branch lengths are drawn to scale.
