Summary
Michigan confirmed a human Eastern Equine Encephalitis case in Roscommon County, the state's first since 2021, and urged residents statewide to guard against mosquito bites.
EEE is among the most dangerous U.S. mosquito-borne diseases, with a 30% fatality rate in symptomatic cases and the highest risk of severe illness in people under 15 and over 50.
Roscommon County is getting extra mosquito trapping and testing as state and local officials monitor humans, pets, wildlife and insect samples for further spread.
Of 5,420 mosquito pools tested in Michigan for arboviruses in 2026, 73 were positive, though no animals have tested positive for EEE so far this year.
