Filed Under: Horses, Diseases, Parasites

West Nile virus (WNV) is a flavivirus that was first identified in Africa during 1937. WNV is considered to be endemic in Africa, Asia, Southern Europe and North America. The virus first appeared in North America around the New York City area in 1999, when wild and zoo birds, horses and humans died of meningoencephalitis. WNV has been found in 225 different wild and captive bird species. Birds are the natural host and reservoir of this virus.
