EHD Detected in Deer Across Four Michigan Counties

The Michigan Department of Natural Resources has confirmed the first cases of epizootic hemorrhagic disease (EHD) in deer for 2025, found in four counties including West Michigan, with the disease being transmitted through midge bites and not contagious to humans or pets. EHD is often fatal but deer can develop immunity, and the DNR advises reporting suspected cases and consuming healthy-appearing venison. The disease tends to appear late summer to early fall, especially after wet springs and hot, dry summers.
