What are signs of chronic wasting disease in deer?

Physical Signs of Chronic Wasting Disease

Chronic wasting disease in deer can manifest with visible physical signs, including excessive thirst, which often leads to the deer visiting water sources more frequently than usual. Weight loss is another common indicator, making the deer appear emaciated. In some cases, the disease can cause the deer’s eyes to become sunken, its muscles to atrophy, and its body to become gaunt. Hunters may notice these changes during the initial stages of the disease, making it essential to monitor deer closely.

Behavioral Changes in Affected Deer

Deer infected with chronic wasting disease may exhibit changes in behavior, such as reduced activity, lack of responsiveness to calls or other stimuli, and increased aggression. These changes can be attributed to the disease’s impact on the deer’s brain and nervous system, leading to a decline in overall health and well-being. In West Virginia, where chronic wasting disease has been detected, hunters are advised to monitor deer behavior closely, particularly if they are acting abnormally or erratically.

Field Identification Techniques

To identify deer with chronic wasting disease in the field, hunters can look for specific signs such as labored breathing, stumbling, or difficulty walking. These signs can be indicative of the disease’s progression, making it essential to handle the deer carefully and humanely. In West Virginia, hunters are required to report any deer found to be diseased or deceased, helping to monitor the spread of the disease and inform management strategies.
