A deadly disease affecting white-tailed deer has been confirmed in Adams County and surrounding counties, according to the Ohio Department of Natural Resources (ODNR). Wildlife officials are urging residents to report sightings of sick or dead deer to help track and contain potential outbreaks.
Epizootic Hemorrhagic Disease, commonly known as EHD, is one of the most widespread illnesses impacting deer in the United States. The disease is spread by the bite of an infected midge, a type of small fly. Once a hard freeze occurs, the insects die off for the winter, ending the spread of new cases. So far, it appears that there have been under 10 confirmed cases in Adams County, but the number is likely larger.
ODNR officials stress that EHD does not affect humans and venison from healthy deer remains safe to consume. However, deer that appear sick should never be harvested for food.
Symptoms typically appear about a week after exposure and may include disorientation, lack of fear of humans, feverish behavior, and swelling of the head, neck, tongue, or eyelids. Deer may also show signs of respiratory distress. Because affected animals often seek out water in the later stages, carcasses are frequently discovered near streams, ponds, or rivers.
While outbreaks can cause high mortality in local deer herds, populations usually rebound within a few years. Midwestern deer, however, have little resistance to EHD and may die within three days of showing symptoms. Currently, there is no treatment available for the disease in wild populations.
The Ohio Department of Agriculture has noted that EHD does not pose a serious threat to livestock. No evidence suggests that the disease can be spread to humans, either by contact with infected animals or by consuming venison from a deer that has been exposed. Still, officials advise hunters to wear rubber gloves when field dressing deer and to avoid processing or consuming any animal that appears sick.
ODNR is requesting public assistance in monitoring outbreaks. Residents who observe a deer behaving abnormally, or who find a deer carcass, are encouraged to report it immediately. Click here for the interactive EHD Map.
