Helping to Combat Chronic
Wasting Disease
Collaborative efforts to address the problem of CWD – in Wisconsin and
across the country – have provided some answers, but much still needs to
be done.
|
Chronic Wasting Disease (CWD) is a disease of the nervous system that results
in distinctive lesions in the brain. CWD affects elk, white-tailed deer, and mule
deer, but has not been documented in livestock or humans. The cause is unknown
and no treatment is available. Infected deer and elk can appear robust and healthy in
the early stages of CWD; it may take several years before they show clinical signs,
after which the disease is fatal. Direct contact between infected and non-infected
animals is the most likely route of trans-mission, but other possibilities are under
consideration, including contamination of soil by excreta from infected animals.
