FIG 1.

Phylogenetic analysis of SARS-CoV-2 representative genome sequences, including two UAMS genomes collected in Arkansas. Available genomes were retrieved from GISAID (https://www.gisaid.org) on 7 July 2020. The color (clade) of the dots was classified according to the mutation marks from the GISAID database nomenclature. We discarded sequences with low quality, i.e., ambiguous bases. The figure was created using Nextstrain. Seven mutations were found in USA/AR-UAMS001/2020, and four mutations were found in USA/AR-UAMS002/2020. Unique mutations between the two strains are shown in blue letters, and common mutations for each strain are shown in red letters.
