Is it possible that CWD is statewide, but hasn't been found yet?
Two complete sweeps of statewide surveillance have been conducted since 2002. Over 150,000 cervids in Wisconsin have been screened for evidence of CWD--a much higher level of sampling than has been done in much of the rest of the U.S. This intense level of sampling would likely have detected another CWD focus like the one detected in 2002 in southern Wisconsin. Consistent surveillance also occurs in areas around depopulated CWD infected game farms and for any deer exhibiting signs of CWD infection.
