Chronic Wasting Disease in Deer and Elk

Chronic wasting disease, or CWD, is a progressive neurological disease that has been observed in deer and elk in Colorado, Nebraska, Wisconsin, South Dakota, Kansas, Montana, New Mexico and Oklahoma. Very little is known about the disease. It damages portions of the animal’s brain and is 100 percent fatal. There is no known treatment or vaccine for CWD. The disease is not present in Arkansas. 

Infected animals may not show any symptoms of the disease. In some stages of the disease, however, infected animals begin to lose control of bodily functions and display abnormal behavior such as staggering, standing with very poor posture and losing fear of humans. Infected animals lose weight rapidly (thus wasting disease) and often stand in or near water and drink excessively. They may also exhibit drooling or excessive salivation. Some of these symptoms are not unique to CWD and are found in other diseases affecting deer and elk. 

It is not known exactly how CWD is spread. Experiments have shown the disease can be spread both directly (animal-to-animal contact) and indirectly (through soil or other surfaces). It is thought that the most common mode of transmission from an infected animal is through saliva, feces and possibly other body secretions. There is evidence that people have spread the disease by moving infected animals.
