West Nile Virus Spreads in US: Interactive Map of Cases
West Nile Virus is spreading in the United States and Canada, with active cases in almost all states.
West Nile virus (WNV) is a potentially serious illness that is contracted through disease-carrying mosquitos. Experts believe WNV is established as a seasonal epidemic in North America that flares up in the summer and continues into the fall.
Prevention measures consist of community-based mosquito control programs that are able to reduce vector populations, personal protection measures to reduce the likelihood of being bitten by infected mosquitoes, and the underlying surveillance programs that characterize spatial/temporal patterns in risk that allow health and vector control agencies to target their interventions and resources.
