Bield:Hunt
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. Pick a state for current status, county-level detections where seeded, transport rules, and testing information.

Always verify with the agency

Disease status changes — new state-level CWD detections are announced periodically, and EHD activity varies year to year. This page summarizes broadly-reported public information for hunter awareness only. Cross-reference state wildlife agency pages and the USDA APHIS distribution map for current data.

How to read these pages

Each state page shows current CWD status, a detection timeline when applicable, county-level records where seeded, transport and testing information, and a hunter FAQ. County pages drill into the specific record with first/most-recent detection years and any EHD activity on file.

Records flagged "estimated" mean we have not personally cross-referenced the specific record against a primary agency report — these are exactly the entries to double-check before relying on them.

Bottom line on safety: CDC and state wildlife agencies recommend testing harvested deer for CWD in CWD-positive areas before consumption, and not consuming meat from CWD-positive deer. EHD is not transmissible to humans — meat from EHD-affected deer is safe to eat per state agency guidance.
