Chronic Wasting Disease (CWD)
Chronic wasting disease (CWD), is a contagious, always-fatal brain disease that affects members of the deer family. It was discovered in Pennsylvania's free-ranging white-tailed deer in 2012 and continues to be a threat to deer and elk in the Commonwealth.
Since then, the number of deer testing positive for CWD has risen and the area in which it is found has expanded.
