The Threat of Chronic Wasting Disease to Cervids
A Fatal Neurological Illness Affecting Deer, Elk, and Moose
Chronic wasting disease (CWD) is a serious and contagious condition that affects animals such as deer, elk, and moose. It is caused by a prion, a type of abnormal protein that can damage brain tissue. CWD is fatal and there is no known cure.
How CWD is Spread
CWD is spread through contact with infected animals or their bodily fluids. This can occur through direct contact, such as when animals lick or groom each other, or through indirect contact, such as when animals share food or water sources. CWD can also be spread through the environment, such as when animals come into contact with contaminated soil or plants.
Symptoms of CWD
The symptoms of CWD can vary depending on the stage of the disease. In the early stages, animals may show no signs of illness. As the disease progresses, animals may experience weight loss, difficulty eating, excessive drinking and urination, and changes in behavior. In the late stages of CWD, animals may become emaciated, have difficulty walking, and lose their fear of humans.
Preventing and Controlling CWD
There is no known cure for CWD, so prevention and control are essential. There are a number of things that can be done to prevent the spread of CWD, including:
- Avoiding contact with infected animals or their bodily fluids
- Properly disposing of carcasses of infected animals
- Limiting the movement of animals between areas where CWD is known to occur
- Educating hunters and other outdoor enthusiasts about CWD
By taking these steps, we can help to protect our deer, elk, and moose populations from this devastating disease.
