Confirmed clinical and veterinary cases of West Nile virus (WNV) infection in Mexico remain restricted to northern Mexico, supporting a unidirectional transmission model from the US into Mexico. Full-length genomic sequencing of nine WNV isolates obtained from Culex spp. mosquito pools in El Paso, Texas (n=7) and Cuidad Juarez, Mexico (n=2) from 2005 to 2010 demonstrates the co-circulation of three independent genetic groups, two of which belong to the southwestern (SW/WN03) genotype and the other to the North American (NA/WN02) genotype. These results indicate ongoing dynamic circulation of WNV between the United States and Mexico.
