West Nile Virus (WNV)

What is West Nile Virus (WNV)?

West Nile is a virus most commonly transmitted to humans by mosquitoes.   

There are no medications to treat or vaccines to prevent WNV infection. Fortunately, most people infected with WNV will have no symptoms. About 1 in 5 people who are infected will develop a fever with other flu-like symptoms, such as headache, body aches and joint pains.  Less than 1% of infected people develop a serious, sometimes fatal, neurologic illness.   

You can reduce your risk of being infected with WNV by using insect repellent and wearing protective clothing to prevent mosquito bites.

You can also reduce your risk by helping to reduce the mosquito population near your home. This can be done by eliminating standing water where mosquitos can breed.
