The state DNR said that 89% of the positive cases were found in the Southern Farmland Zone.
The newly identified deer, a 4.5-year-old white-tailed buck, was harvested by a landowner helping the DNR with ongoing sampling.
Counties reporting their first CWD cases are Audrain, Callaway, Lewis, Marion, Miller, Morgan, and Texas, all of which abut CWD-positive areas.
The rest of the 23 CWD-positive deer harvested by hunters during the 2024-25 hunting season were found in Allen, Hardin, Marion, and Wyandot counties.
The newly affected counties, identified during the April 2024 to March 2025 CWD surveillance season, include Cedar, Davis, Shelby, Story, and Wapello.
The deer in Adams County, in west-central Illinois, is the first documented case outside of the state's northern CWD-endemic region.
CWD-positivity in hunter-harvested animals ranged from 2.3% in elk to 29% in white-tailed bucks.
The infected white-tailed deer was found in the Prince William County, Virginia, part of the park.
Wyoming's Horse Creek becomes the 4th elk feeding ground in the state to test positive since January, and Louisiana's Catahoula Parish reports the first case in wild deer outside of Tensas Parish.
Grant County, in the northeast part of the state, was added to the state's CWD containment area in 2015 because it is near other counties with CWD-positive cases.
