Identifying the ancestral relationship of the VSIV Epidemic lineage in the US. (A) a maximum likelihood tree inferred using 98 full-length genomic VSIV sequences, and the relationship between the epidemic VSIV lineage circulating in the USA during 2019–2020 and multiple earlier isolates from GenBank is shown. Branches are labeled with bootstrap support values. NA: North America, CA: Central America, SA: South America. Percentages in parentheses represent the average pairwise nucleotide identity between epidemic lineage sequences and the corresponding older isolate. (B) Closeup from the phylogenetic analysis showing the ancestral relationship between the epidemic lineage and isolates from Chiapas, Mexico, IN0817CPB, and IN1017CPB.
