CWD Detected in Yellowstone National Park's Mule Deer

Yellowstone National Park and the Wyoming Game and Fish Department have confirmed the presence of chronic wasting disease (CWD) in an adult mule deer buck found near Yellowstone Lake. This is the first confirmed case of CWD in the park. CWD is a contagious and fatal disease affecting deer, elk, and moose, with no known treatment or vaccine. The disease has spread across Wyoming since the mid-1980s. Yellowstone staff will increase collaboration with state agencies, monitor for CWD in other wildlife, and investigate carcasses for testing. Visitors are advised to report sick or dead wildlife and avoid contact with them, as well as refrain from consuming animals suspected or confirmed to have CWD.
