West Nile virus in Mexico: evidence of widespread circulation since July 2002

Emerg Infect Dis. 2003 Dec;9(12):1604-7. doi: 10.3201/eid0912.030564.

Abstract

West Nile virus (WNV) antibodies were detected in horses from five Mexican states, and WNV was isolated from a Common Raven in the state of Tabasco. Phylogenetic studies indicate that this isolate, the first from Mexico, is related to strains from the central United States but has a relatively high degree of sequence divergence.
