On Nov 21 officials at the Maryland Department of Agriculture’s (MDA) Animal Health Program confirmed that a symptomatic horse from Baltimore County tested positive for the the non-neurotropic form of equine herpesvirus-1 (EHV-1) at the Frederick Animal Health Laboratory. The horse, of unreported age, gender and breed, had been stabled in a barn with three other horses at a facility that houses 25 horses total, none of which currently show elevated temperatures or other signs of EHV-1.

The affected horse was euthanized Nov. 22 due to complications.
