The Pennsylvania Gaming Commission reports outbreaks of epizootic hemorrhagic disease (EHD) in deer across Mercer, Lawrence, Butler, and Erie counties, caused by infected midges, with no current treatments available. The bluetongue virus (BT) also affects deer, causing severe symptoms and potential death, but some deer survive with chronic issues. Domestic livestock can also be affected, and wildlife populations typically recover within a few years.
Several counties in Maryland are experiencing an outbreak of Epizootic Hemorrhagic Disease (EHD) among white-tailed deer, caused by a virus transmitted through midges, with no threat to humans. The disease is common annually and typically resolves with the onset of cold weather, and affected deer should not be consumed if they have open sores. Authorities advise reporting sick or dead deer to local wildlife offices.
The Michigan Department of Natural Resources has confirmed the first cases of epizootic hemorrhagic disease (EHD) in deer for 2025, found in four counties including West Michigan, with the disease being transmitted through midge bites and not contagious to humans or pets. EHD is often fatal but deer can develop immunity, and the DNR advises reporting suspected cases and consuming healthy-appearing venison. The disease tends to appear late summer to early fall, especially after wet springs and hot, dry summers.
Michigan has reported its first cases of epizootic hemorrhagic disease (EHD) in deer for 2025, confirmed in four counties, with the disease transmitted by biting flies and not affecting humans or pets.

An outbreak of Epizootic Hemorrhagic Disease (EHD) has been confirmed in deer across several counties in West Virginia's Mid-Ohio Valley, caused by infected midges, with the outbreak likely to end with the first frost killing the midges. The disease has resulted in multiple deer deaths, but some animals survive and develop immunity.
