DNR verified EHD in two wild deer located in Washington County

The Wisconsin Department of Natural Resources (DNR) has recently verified that the virus causing epizootic hemorrhagic disease, commonly known as EHD, has been identified in two wild deer located in Washington County. These confirmed cases were found specifically near the village of Richfield and the city of West Bend. The investigation was initiated following multiple reports from local landowners and residents who observed clusters of dead deer, many of which were discovered in or near bodies of water. While the sight of such clusters can be distressing to the local community, wildlife experts emphasize that the state’s deer herd remains robust and that these localized events typically do not result in long-term negative impacts on the overall population.

EHD is a viral condition transmitted to deer through the bites of small insects known as midges or biting gnats. The disease follows a seasonal pattern, primarily occurring between August and October, and naturally concludes with the arrival of the first hard frost which eliminates the midge population. It is important for the public to understand that EHD does not pose any health risk to humans. The virus cannot be transmitted to people through midge bites, the handling of infected animals, or the consumption of venison from deer that were carrying the virus. Infected deer often exhibit symptoms such as excessive foaming at the mouth, general weakness, and a lack of fear toward humans. Because the virus causes a high fever, deer are frequently drawn to water sources to cool themselves, leading to the common occurrence of carcasses being found near lakes and streams.

The DNR maintains an active monitoring system and encourages the public to report sightings of symptomatic or deceased deer. While the agency prioritize testing for new counties or specific new locations, all reports are cataloged to help track the progression and impact of the outbreak. Reports can be filed through the official DNR online Sick or Dead Wildlife Reporting Form, via email, or by telephone. For safety reasons, officials advise against handling wildlife carcasses, as they may harbor other pathogens. If a carcass must be moved for disposal, the use of gloves and strict adherence to hygiene protocols are strongly recommended to ensure public safety.
