CWD & EHD by state and county

Deer disease, state by state.

Chronic Wasting Disease (CWD) and Epizootic Hemorrhagic Disease (EHD) are the two diseases most likely to affect a deer hunter's season. They behave very differently — CWD is a slow-moving prion disease that persists once established; EHD is an annual viral outbreak driven by midges and weather. Both shape regulations, transport rules, and risk decisions.

Always verify with the agency

Bield aggregates publicly reported state and federal records. Detections evolve weekly. Confirm current zone boundaries and transport rules with your state F&W and USDA APHIS before hunting.

How to read these pages

We tag detection records as Official, Agency-reported, or Estimated — verify. When a record is estimated, the badge flags it explicitly so you know to cross-check before relying on it. Both CWD and EHD venison are safe to consume by current CDC and USDA guidance — CDC recommends testing in CWD zones; EHD is not a human pathogen.

Track herd health on your land.

State maps tell you the perimeter. Bield: Hunt records every observation and recovery, so the trend on your property shows up before agency reports do.
