A newly emergent genotype of West Nile virus is transmitted earlier and more efficiently by Culex mosquitoes.

The American journal of tropical medicine and hygiene - 1 Aug 2007

Abstract excerpt

Studies examining the evolution of West Nile virus since its introduction into North America have identified the emergence of a new dominant genotype (WN02) that has displaced the introduced genotype (NY99). The mechanistic basis for this displacement, however, remains obscure. Although we found no detectable difference in vitro between the genotypes in either replication or fitness, there were significant...
