Chronic wasting disease, first identified in 1967, initially affected a captive Rocky Mountain elk and mule deer. While it may share similar symptoms with mad cow disease in deer, chronic wasting disease is a distinct condition. Experts believe it may have originated from scrapie, a similar disease that affected domestic sheep in the early 1900s. Interestingly, chronic wasting disease can also occur naturally in the wild, making it a potential source of infection.
Understanding Chronic Wasting Disease
Chronic wasting disease (CWD) is a highly contagious neurological disorder that specifically targets mule deer, white-tailed deer, moose, elk, and reindeer. Also known as transmissible spongiform encephalopathy (TSE) or prion disease, CWD belongs to a group of fatal conditions that progressively affect the brain and nervous system of various animals, including humans.
What Are the Signs of Chronic Wasting Disease?
Chronic wasting disease is a neurological disorder that leads to the degeneration of the brain in affected animals. This results in abnormal behavior, emaciation, loss of bodily functions, and ultimately death. The most prominent and consistent symptom of chronic wasting disease is gradual weight loss over time. Even though affected animals continue to eat, they consume smaller amounts of food, leading to a gradual decline in their overall body condition. In the later stages of the disease, excessive drinking and urination are commonly observed signs.
