West Nile Virus (WNV)
West Nile virus is carried by certain types of mosquitoes in Michigan. It is a potentially serious disease that can affect anyone, but people over age 60 are more likely to get the more severe form of WNV illness. The risk of bites from infected mosquitoes is highest for people who work or play outdoors. Wearing insect repellent when outdoors (especially at dawn and dusk) is important to prevent WNV.
Sick acting or dead birds, especially crows and blue jays may be an indication of WNV in a community. To report sick acting or dead wildlife to the Michigan Department of Natural Resources click here.
