There's expert opinion that Wisconsin is doing the right thing to stop Chronic Wasting Disease.
A panel of seven UW Madison professors in the animal health and related fields say the best way to combat the deadly brain disease is to quickly eliminate it while it's confined to a small area.
The State Department of Natural Resources wants to kill all the deer in a 389-square-mile area around Mount Horeb. That's where three deer infected were found this past February. The panel also says the state should create a Chronic Wasting Disease Advisory Council.

Chronic Wasting Disease
- To date, chronic wasting disease has been found only in members of the deer family in North America. Animals include: Rocky Mountain Elk, mule deer, white-tailed deer, and black-tailed deer.
- There is ongoing research to explore the possibility of transmission of chronic wasting disease to other species.
- Most cases of chronic wasting disease occur in adult animals.
- The disease is progressive and always fatal.
- The most obvious and consistent clinical sign of chronic wasting disease is weight loss over time.
- Behavioral changes also occur in the majority of cases, including decreased interactions with other animals.
What Causes chronic wasting disease?
- The agent responsible for chronic wasting disease has not been completely characterized.
- There are three main theories on the nature of the agent that causes chronic wasting disease:
- The agent is a prion, an abnormal form of a normal protein, known as cellular prion protein, most commonly found in the central nervous system.
- The agent is an unconventional virus.
- The agent is a virino, or "incomplete" virus composed of nucleic acid protected by host proteins. The chronic wasting disease agent is smaller than most viral particles and does not evoke any detectable immune response or inflammatory reaction in the host animal.
