chronic wasting disease

U.S. Geological Survey

Chronic Wasting Disease is a wildlife illness similar to Mad Cow Disease.  It’s rooted itself in the Mountain West and is thinning herds throughout the region.

Nevada and Idaho are the only states in our region with no confirmed cases of the highly contagious and fatal wildlife infection. But that doesn’t mean it hasn’t made it there.

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.
