LANSING, Mich. – Aerial treatment to combat the potentially deadly mosquito-borne Eastern Equine Encephalitis (EEE) is expected to occur in three counties tonight announced the Michigan Department of Health and Human Services (MDHHS).

  • Block 3-1 and 3-2 Oakland County and Block and 3-3 in Livingston and Oakland counties.
  • Block 11-1 in Livingston County.
  • Block 12-1 in Calhoun County.

Schedules are weather dependent and may change. More than 373,000 acres have been treated to date.

“We have taken this action to protect Michiganders from this potentially dangerous mosquito-borne disease,” said Dr. Joneigh Khaldun, chief medical executive and chief deputy for health at MDHHS. “We urge residents to continue taking precautions against mosquito bites and encourage local officials in the affected counties to consider postponing, rescheduling or cancelling outdoor activities occurring at or after dusk until the first hard frost of the year.”

Currently, a Barry County resident has been confirmed with EEE in addition to 32 animals - 30 equine and two deer. Impacted counties are Allegan, Barry, Calhoun, Clare, Ionia, Isabella, Jackson, Kent, Livingston, Mecosta, Montcalm, Newaygo and Oakland.
