Chronic wasting disease (CWD) has spread to deer in Gettysburg National Military Park (NMP) in Pennsylvania and Carbon County and additional parts of Uintah County in Utah, officials say.

Recent white-tailed deer culling operations and sample testing in Gettysburg NMP and Eisenhower National Historic Site have yielded two CWD cases, marking the first positive finding in the NMP, the National Park Service reports.

“Park staff are coordinating their response with the Pennsylvania Game Commission and the National Park Service (NPS) Biological Resources Division to ensure a consistent, science-based approach to monitoring and limiting the spread of the disease,” the news release said.

CWD was first detected in Pennsylvania in 2012. In 2024, three nearby national parks in Maryland (Antietam National Battlefield, Monocacy National Battlefield, and Harpers Ferry National Historical Park) reported their first cases.

Most positive CWD samples collected in Utah from July 1, 2025, to February 23, 2026, were from northeastern and southeastern Utah, but one was located in Scofield, Carbon County—that county’s first case, the Division of Wildlife Resources (DWR) reports.
