Eastern Equine Encephalitis (EEE)

(September 19, 2019) The Michigan Department of Health and Human Services (MDHHS) has alerted local public health and health care providers to increasing Eastern Equine Encephalitis (EEE) activity in the state. Seven cases of EEE have occurred in residents from Barry, Berrien, Cass, Kalamazoo and Van Buren counties. Three cases were fatal.

The most important thing that our residents can do to protect themselves from any mosquito-borne disease is to avoid mosquito bites. This can be accomplished by:

  • Using Insect Repellent with one of the active ingredients below. When used as directed, EPA-registered insect repellents are proven safe and effective, even for children.

    • DEET

    • Picaridin

    • IR3535

    • Oil of lemon eucalyptus (OLE) or para menthane-diol (PMD)

    • 2-undecanone

  • Wearing long-sleeved shirts and long pants when outdoors. Apply insect repellent to clothing to help prevent bites.  Treating clothes/uniforms with permethrin will also help repel mosquitos as well as ticks (see https://tickencounter.org/prevention/clothing_only_repellent_videos for how to’s)

  • Maintaining window and door screening to help keep mosquitoes outside.

  • Emptying water from mosquito breeding sites around the home, such as buckets, unused kiddie pools, old tires or similar sites where mosquitoes may lay eggs.

  • Using nets and/or fans over outdoor eating areas.
