Since the fall of 2020, 49 wild deer in Ohio have tested positive for CWD, all in Allen, Hardin, Marion, and Wyandot counties (one in Allen, one in Hardin, 10 in Marion, 37 in Wyandot). Allen County’s first case of CWD was confirmed in November 2023.

CWD is a fatal neurological disease that affects white-tailed deer and other similar species, including mule deer, elk, and moose. According to the Centers for Disease Control and Prevention, there is no strong evidence that CWD is transmissible to humans.

Sampling for CWD will continue in the 2024-25 deer hunting season. A disease surveillance area was established in 2021 to monitor the spread of CWD. Additional hunting opportunities and special regulations are in effect in the disease surveillance area, which includes all of Hardin, Marion, and Wyandot counties as well as Auglaize and Jackson townships in Allen County. The Ohio Wildlife Council approved the inclusion of Auglaize and Jackson townships of Allen County in the disease surveillance area for the 2024-25 hunting season.

The ODNR Division of Wildlife has extensively monitored and tested deer in the disease surveillance area since CWD was discovered in the wild in 2020. The Division of Wildlife has conducted routine surveillance for CWD since 2002, with approximately 39,000 deer tested. CWD has been detected in 30 states and four Canadian provinces. The disease was first discovered in the 1960s in the western U.S. More information about this disease is available at cwd-info.org.

The mission of the Division of Wildlife is to conserve and improve fish and wildlife resources and their habitats for sustainable use and appreciation by all. Visit wildohio.gov to find out more.
