Chronic Wasting Disease (CWD)

What is CWD?
Chronic Wasting Disease (CWD) is a transmissible spongiform encephalopathy (TSE) affecting farmed and free-ranging deer, elk, and moose, in North America.
CWD is a progressive, fatal, degenerative neurological disease. It was first recognized in 1967 as a clinical ‘wasting’ syndrome of un- known cause in captive mule deer in Colorado. CWD belongs to the family of diseases known as transmissible spongiform encephalop- athies (TSEs). TSEs include a number of different diseases affecting animals or humans including bovine spongiform encephalopathy (BSE) in cattle, scrapie in sheep and goats, and Creutzfeldt-Jacob disease (CJD) in humans. Although CWD shares certain features with other TSEs, it is a distinct disease affecting only deer, elk, and moose.
To learn more about CWD and how you can help prevent the spread of the disease, watch our video about Chronic Wasting Disease.
