West Nile Virus / Bird Testing


Welcome to the Princeton Health Department's information page on West Nile Virus.

West Nile virus (WNV) is most commonly transmitted to humans by mosquitoes. You can reduce your risk of being infected with WNV by using insect repellent and wearing protective clothing to prevent mosquito bites. 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 symptoms. Less than 1% of infected people develop a serious, sometimes fatal, neurologic illness.

The Princeton Health Department is actively working with the New Jersey Department of Health to control mosquitoes in our area. You can do your part by reducing stagnant water around your property. Buckets, stagnant ponds, even bottle caps can be a breeding habitat for mosquitoes. You can also report dead/ill birds to the Princeton Health Department.
