EEE Activity in Michigan for 2019 – Confirmed Cases: MDARD Confirms 17 Cases of EEE

EEE is transmitted through the bite of an infected mosquito. Horses are very susceptible to EEE; cases in dogs are extremely rare. There is a vaccine for horses, and owners should work with their veterinarian. Horses and other animals can be protected by applying mosquito repellent approved for that type of animal and bringing animals indoors from early evening until after sunrise when mosquitoes are most prevalent.
