West Nile Virus from Blood Donors, Vertebrates, and Mosquitoes, Puerto Rico, 2007
Abstract
West Nile virus (WNV) was isolated from a human blood donor, a dead falcon, and mosquitoes in Puerto Rico in 2007. Phylogenetic analysis of the 4 isolates suggests a recent introduction of lineage I WNV that is closely related to WNV currently circulating in North America.
