Chronic wasting disease has been confirmed for the first time in Yellowstone National Park in a mule deer found dead near Yellowstone Lake, park officials said Tuesday.

The mule deer, an adult buck, died mid-October after making its way to the southeastern part of the national park during the past seven months, a Yellowstone National Park spokesperson said. The deer had been captured and collared by Wyoming Game and Fish Department crews in March as part of a population study.

Park spokesperson Morgan Warthin said multiple tests confirmed the deer had CWD, which affects the cervid family of white-tailed and mule deer, elk, and moose and is 100% fatal. There is no current vaccine or cure for CWD.
