CWD

A neurodegenerative illness called chronic wasting disease is spreading among deer and elk in our region. Now, researchers at Colorado State University say they’ve found a new way to study the disease -- and another indication that it might eventually become capable of sickening people.

Chronic wasting disease is crippling deer populations in the Mountain West, around the country and in bordering Canadian provinces. It's not a bacterium or a virus or even a fungus, but caused by something called a prion, a type of protein that all mammals have in their bodies.

Earlier this week, a conservation coalition filed a lawsuit against the National Elk Refuge in Jackson for continuing to provide supplemental feed to elk in the winter, especially since Chronic Wasting Disease has been detected in Teton County.

A case of chronic wasting disease, or CWD, was found in a deer outside Meeteetse. The white-tailed buck was legally harvested by a hunter southwest of the town, and was later sampled by the Wyoming Game and Fish Department. Testing confirmed the buck positive for CWD.

A new case of Chronic Wasting Disease (CWD) was found in a harvested mule deer buck 12 miles outside of Dubois this week. It was found in hunting area 128 and neighbors area 171 where CWD had been found earlier this year. According to Wyoming Game and Fish Wildlife supervisor in Lander, Jason Hunter, it’s not surprising that the disease has spread.

New research had found that the fatal brain illness, chronic wasting disease (CWD), has a direct impact on the population decline of white-tailed deer. University of Wyoming graduate student David Edmunds worked on the study and said the research shows the disease lowers the survival rate of female deer under the age of seven. As of right now, there is no way to manage the disease once introduced into a population of deer.
