Detailed explanation-1: -West Nile virus (WNV) is the leading cause of mosquito-borne disease in the continental United States. It is most commonly spread to people by the bite of an infected mosquito. Cases of WNV occur during mosquito season, which starts in the summer and continues through fall.

Detailed explanation-2: -West Nile encephalitis is a mosquito-borne infection of the brain caused by West Nile virus, a close relative of St. Louis encephalitis virus.

Detailed explanation-3: -WN virus is maintained in nature in a mosquito-bird-mosquito transmission cycle. Mosquitoes of the genus Culex are generally considered the principal vectors of WNV, in particular Cx. Pipiens. WNV is maintained in mosquito populations through vertical transmission (adults to eggs).
