'Zombie Deer Disease' Detected in Yellowstone National Park

The fatal disease, which affects deer, elk, and moose, has been found for the first time in the park, prompting increased surveillance and warnings to visitors.

Chronic wasting disease, also known as 'zombie deer disease,' has been detected in Yellowstone National Park for the first time.
The disease is a contagious, fatal illness that affects deer, elk, and moose, causing behavioral changes and eventual death.
The disease has been found in animal populations in at least 31 U.S. states, Canada, and several other countries, but there are no reported cases of infection in humans.
The disease is transmitted via bodily fluids and waste, and prions can remain in the environment for a long time, posing a significant challenge to wildlife management.
Yellowstone is increasing monitoring and sample testing, and updating its surveillance plan, while warning visitors to stay away from wildlife.
