West Nile Virus Background Information
The West Nile virus (WNV) is transmitted by a mosquito vector and can result in encephalitis in infected humans and equine. WNV can also result in wild and domestic bird mortality. WNV was first discovered in a woman from the West Nile District of Uganda in 1937. WNV spread across areas of Africa, Eastern Europe, West Asia, and the Middle East, eventually appearing in the Eastern United States in 1999.
