Michigan has confirmed its second case of Eastern equine encephalitis (EEE) in a domestic animal in 2026 after an 18-month-old quarter horse filly in Roscommon County tested positive. The horse was humanely euthanized. A human EEE case was also reported in Roscommon County earlier this summer, Michigan’s first human case since 2021.
The state’s first domestic animal case this year involved an under-vaccinated quarter horse colt in Clare County in late August. State Veterinarian Dr. Nora Wineland said the cases demonstrate that EEE and other mosquito-borne viruses are circulating in Michigan and emphasized vaccination and mosquito control.
EEE cannot spread directly from horses to other horses or people, with cases typically occurring in late summer and early fall. Officials recommend vaccinating horses against EEE and West Nile virus, eliminating standing water, using appropriate insect repellents, housing animals during peak mosquito activity, and contacting a veterinarian when signs of illness develop.
