West Nile Virus

West Nile Virus (WNV) is a mosquito-borne virus that affects humans and other animals, particularly horses. The effects of WNV infection in horses can range from mild to potentially fatal inflammation of the brain.

WNV is a notifiable disease to the Department for Environment, Food and Rural Agency (DEFRA) in England and Wales, and in Scotland and Northern Ireland to the equivalent government authority.
