West Nile Virus

West Nile Virus (WNV) is a potentially serious illness with higher incidence in the summer and fall. West Nile Virus most commonly affects birds, but can also affect humans and other animals. Horses are especially susceptible to West Nile Virus and can die from it, but there is a vaccine available for horses that helps protect them.

WNV is transmitted mainly through mosquito bites. West Nile Virus has also rarely been transmitted to humans through blood transfusions, organ transplants, breastfeeding and from mother to baby during pregnancy. There is no vaccine available for humans to prevent West Nile Virus infection at this time.

Prevention of West Nile Virus infection is by prevention of mosquito bites. This includes covering up skin, using insect repellents and reducing the numbers of mosquitoes in your environment.
