Veterinary-Medical-Symbol-175x300According to the Maryland Department of Agriculture, as of 9 a.m. this morning, there have been no new cases of Equine Herpes Virus-1 (EHV-1) reported since April 19, when two horses stabled at Days End Farm Horse Rescue in Howard County tested positive for the non-neuropathogenic strain of the virus. The farm was placed on 30-day quarantine when the first case was confirmed on April 18. There has been no movement of horses on or off the farm since that date.

According to MDA, the farm’s attending veterinarian and animal health inspectors from the Maryland Department of Agriculture have been closely monitoring all horses on the farm and have found no new cases of the virus. The quarantined farm has taken additional measures to prevent the spread of EHV-1 by enacting strict biosecurity protocols, helping to ensure that no visitors or vendors carry the disease onto other farms.

“We have received many calls from concerned stable owners and event organizers since the original case was confirmed last month,” said State Veterinarian Dr. Michael Radebaugh. “We have no reason to believe that the disease has spread beyond this specific farm. Horses are latent carriers of the EHV-1 virus, and under certain conditions, horses will breakout with this disease. In Maryland, we experience a few isolated cases of EHV-1 every year.”

Recent cancellations of equine events around the state have led to a heightened level of concern; however, these were precautionary measures taken by the event organizers, and not by the Department.

Though the virus appears to be contained, the Department reminds all horse owners to remain vigilant in protecting the health of their animals. If a horse displays symptoms of EHV-1, veterinarians should call the department’s Animal Health program at 410-841-5810 or 410-841-5971 (after hours). EHV-1 is a reportable disease in Maryland.
