Chronic Wasting Disease (CWD) was not detected in the 862 deer
collected during the DNR Division of Fish and Wildlife’s 2008 CWD
In every year since 2002, DFW employees have been collecting CWD
samples from hunter-harvested deer during the opening weekend of
firearm season. Since 2007, these efforts have been supplemented
with collecting road-killed samples throughout the year. CWD has
not been detected in the more than 10,000 deer collected during the
entire monitoring period.
CWD is one of a group of diseases called Transmissible
Spongiform Encepalopathies (TSEs). Other examples of TSEs include
scrapie in sheep and Creutzfeldt-Jakob disease in humans. The
agents of CWD are called prions, which are abnormal,
protease-resistant forms of cellular proteins normally synthesized
in the central nervous system and lymphoid tissues. Prions that
cause CWD are highly resistant to heat or disinfectant, and can be
transferred to other deer through direct or indirect contact. No
study has ever proven that CWD is transmissible to humans.
CWD has been reported in free-ranging deer herds in Wisconsin,
Illinois and West Virginia, among other states. Indiana has never
detected CWD within its free-ranging or captive deer herds. For
