Fight the Bite LogoWest Nile virus (WNv) is a mosquito-borne virus that can cause West Nile Non-Neurological syndrome (formerly known as West Nile fever) or occasionally the more serious West Nile Neurological Syndrome.

WNv is transmitted to humans primarily through the bite of an infected mosquito. WNv can affect anyone – one in five people who do become infected become ill. Severe illness associated with the virus is rare, but risk increases with age. However, the good news is that you can take some simple steps to protect yourself and others.
