Chronic wasting disease is an incurable illness in deer that causes neurological problems, much like mad cow disease. The DNR found Indiana’s first case of chronic wasting disease last year.

The disease — which is 100% fatal — causes a deer's nervous system to shut down until they die, but there's no evidence of the disease spreading to humans.

By analyzing mule deer herds in Wyoming, researchers predict that hunters can help slow the spread of CWD by increasing harvest rates of adult deer.
