L = large; M = medium; S = small. Birao, Bozo, Germiston, Lokern, Mboke, Northway, Santa Rosa, and Shokwe viruses are not included because their genomes have not been fully sequenced. Fort Sherman, Playas, Tlacotalpan, and Xingu viruses are not included because they have been classified as antigenic variants of CVV.36,37 Iaco and Tucunduba viruses are not included because they have been reclassified as Wyeomyia group viruses.34 Underlined values were obtained when the genomic sequence of a reassortant was aligned to the genome sequence of one of its donor viruses (these values were excluded when calculating means and ranges). Abbreviations are defined in Table 1. Genbank accession numbers used for the analysis are listed in the footnotes of Tables 3–5.
