EHD Outbreak Decimates Wisconsin Deer Across SE Counties

An outbreak of epizootic hemorrhagic disease (EHD) spread by midges has killed at least 600 white-tailed deer across Ozaukee, Washington, and Waukesha counties in southeastern Wisconsin as of late August. The DNR confirmed EHD in samples from Washington County and continues to receive reports of deer deaths in the three counties. EHD is not transmissible to humans; it typically causes rapid illness and death in deer, with survivors developing antibodies. Local governments are disposing of carcasses and the DNR will test only if a case appears far from the known outbreak area. Outbreaks typically end after the first hard frost. Residents are urged to report sick or dead deer via the DNR reporting form, email, or phone.
