Chronic Wasting Disease of Elk and Deer

Filed Under: Diseases

First reported in the late 1960’s in captive mule deer found in Colorado, Chronic Wasting Disease (CWD) has now been found in cervids (hoofed ruminant mammals whose males of the species have horns) in much of the northwestern United States and several Canadian provinces.  Surveillance studies in hunter-harvested animals from 1996-1999 found that CWD infected approximately 5% of the mule deer, 2% of the white-tailed deer, and <1% of the elk in the Colorado and Wyoming areas of the United States.  The geographical area and number of animals infected continues to grow.
