CWD Research and Statistics
Chronic Wasting Disease (CWD) is a transmissible neurological disease of deer and elk that produces small lesions in the brains of infected animals. Deer with the disease appear thin and emaciated. They tend to behave differently than normal deer. They drink large amounts of water and may be very uncoordinated.

CWD is classified as a transmissible spongiform encephalopathy (TSE) and is similar to mad cow disease in cattle and scrapie in sheep.

Although CWD is a contagious, fatal disease among deer and elk, research suggests that humans, cattle and other domestic livestock are resistant to natural transmission. While the possibility of human infection remains a concern, it is important to note there have been no verified cases of humans contracting CWD.
