Eastern Equine Encephalitis

Eastern Equine Encephalitis, Placeholder Image
  • Eastern Equine Encephalitis (EEE) is carried by certain types of mosquitoes in Michigan. It is a potentially serious disease that can affect anyone, but children and people over age 60 are more likely to get the more severe form of EEE illness. EEE is found primarily in areas with swamps and bogs.  The risk of bites from infected mosquitoes is highest for people who work or play outdoors in these areas. Wearing insect repellent when outdoors (especially at dawn and dusk) is important to prevent EEE.  

    EEE is also a serious disease in horses.  Protecting horses with approved EEE vaccines is an important prevention measure.
