Estimated dates of divergence derived from partial E2 and complete genome sequences for major Mayaro virus lineages, Venezuela, 2010*
| Lineage | Date for time of MRCA for partial E2–E1 sequences (95% HPD) | Date for time of MRCA for complete genome sequences (95% HPD) |
|---|---|---|
| Venezuelan outbreak strains | 2007 (2003–2009) | 2008 (2007–2009) |
| Northeast Peruvian and Bolivian clade | 1952 (1935–1967) | 1966 (1940–1970) |
| South/Central Peruvian clade | 1968 (1953–1980) | 1977 (1967–1987) |
| Brazilian genotype D clade | 1864 (1822–1904) | 1872 (1836–1906) |
| Brazilian genotype L clade | 1877 (1836–1915) | 1905 (1882–1926) |
| Peruvian genotype N clade | 1750 (1657–1833) | 1746 (1658–1823) |
*E, envelope; MRCA, most recent common ancestor; HPD, highest posterior density.
