Chronic wasting disease, a deadly neurological infectious disease that affects deer, elk and moose, is spreading across North America. Most recently detected in North Carolina in March 2022, CWD has been confirmed in 30 U.S. states and four Canadian provinces, as well as Norway, Finland, Sweden and South Korea. Dr. Allan Houston, a professor of forest and wildlife ecology at the University of Tennessee’s 18,400-acre Ames AgResearch and Education Center in western Tennessee, explains what is known about CWD and what wildlife scientists are trying to learn.
