West Nile Virus Disease 2018

West Nile virus (WNV) is transmitted to humans and some animals through the bite of an infected mosquito. Persons are at greatest risk of exposure to infected mosquitoes from July through September with peak activity late July to August. There are no human vaccines or treatment for WNV. Prevention of mosquito bites is the most important way to reduce your risk of mosquito-borne diseases.
