What is Chronic Wasting Disease (CWD)?
Chronic Wasting Disease (CWD), a prion disease of elk and deer, presents a disturbing challenge in combatting prion disease. CWD is highly contagious among cervids, spreading from animal to animal through environmental contamination, including soil and plants, and has spread from 2 to 22 states since 2000.

Can CWD spread to humans?
It is not yet known. However, an ongoing study points to the fact that macaques (primates that are genetically close to humans) acquired CWD through oral consumption of infected deer meat. This opens the question of whether humans can acquire CWD from eating deer meat. And if so, how will that disease appear in human brain tissue? The National Prion Disease Pathology Surveillance Center, at Case Western Reserve University in Cleveland, Ohio, is studying this and collaborating with researchers to learn more.
