Chronic Wasting Disease (CWD) is always lethal to deer that contract the prion based disease and has been known in North America for decades. CWD was discovered in Wisconsin in 2002 but not all hunters are happy with how the DNR has managed the disease in the state. The Wisconsin Rapids Tribune  has a write up about what some hunters think of the management polices and the course of CWD in the state.
"I don't think CWD is enough of a threat to do what they're doing to the deer herd and to the state's hunting," said Andy Townsend, 24, of Milton, who shot and later ate a CWD-positive buck in January. "I'm friends with 100 guys, and 99 percent think this is getting kind of absurd and they should just let (CWD) run its course."
