Indian Hill is experiencing a large number of deer that are sick or dead within the community. This is an unprecedented outbreak of Epizootic Hemorrhagic Disease (EHD) in the city, that is also sweeping across Ohio, decimating the deer population and raising concerns among wildlife officials. This article provides some EHD information for public awareness. The Ohio Division of Natural Resources (ODNR) is aware of the disease that is spreading around the eastern part of Hamilton County. Here is the link that shows what counties have been impacted this summer;
EHD is a viral disease that primarily affects white-tailed deer, but can also affect other animals such as mule deer and black-tailed deer. EHD is NOT a threat to humans or other animals, such as dogs and cats. The viral disease is spread by biting flies called midges, that transmit the virus from infected deer to healthy deer. EHD is one of the most common diseases of white-tailed deer in the United States. Outbreaks occur seasonally with the life cycle of the insects that spread the virus, and usually peak in late summer to early fall when midge population is high. The severity of outbreaks varies regionally and annually with drought and other factors, and deer in some regions have more natural immunity to the virus.
Reports of EHD start in late July and August. Conditions, like prolonged drought, can create favorable breeding sites for midges in shallow, muddy water. Also, high summer temperatures can increase midge populations. The spread of EHD slows in September and typically ends when the first frost arrives, killing the midges and stopping the transmission.
Deer suffering from EHD experience high fever and dehydration, so they often move toward water to drink and cool off. Sick and dead deer are often found in or near water during outbreaks. EHD typically progresses rapidly, leading to death within a few days. The virus is highly contagious and can spread quickly through the deer population, causing significant mortality.
The 2025-26 Ohio Deer Season starts September 27th and runs through February 1st. Until opening day, Indian Hill officials are closely monitoring the deer population and tracking reports of sick or deceased deer within the community. While ODNR assures that EHD-infected deer are safe for consumption, it is advisable to exercise caution. ODNR suggests it’s best to err on the side of caution. Depending on the illness, a deer can be unfit to eat. If you locate a sick or dead deer please contact the Rangers with the location.
