CWD Symptoms in Elk vs. Deer — How Do They Differ?

Identifying CWD Symptoms in Elk

Elk infected with chronic wasting disease often display a range of visible symptoms, including significant weight loss, typically exceeding 20-30% of their initial weight. Their coats may become roughened and dull, with a distinct change in color, particularly around the muzzle, eyes, and ears. Additionally, elk may exhibit pronounced tremors, particularly in their head and legs, which can be a strong indicator of the disease.

Distinguishing CWD Symptoms in Deer

Deer infected with chronic wasting disease may exhibit somewhat different symptoms, with a more gradual onset of weight loss, typically around 10-20% of their initial weight. They may appear more lethargic and experience difficulty walking, often displaying a reduced stride and an unsteady gait. Deer may also exhibit changes in their behavior, including increased restlessness and a lack of response to their surroundings.

Monitoring and Management of CWD

Effective management of chronic wasting disease involves monitoring the health of elk and deer populations, as well as implementing strict protocols for handling and disposing of infected animals. This includes the use of mandatory testing for hunter-harvested animals, as well as the implementation of regulated hunting seasons to minimize the risk of transmission. Landowners and hunting guides should be aware of these regulations and adhere to them to prevent the spread of CWD.
