This afternoon, Thursday, January 18, 2018, the Maryland Department of Agriculture announced that a Baltimore County horse was euthanized at the University of Pennsylvania’s New Bolton Center on Tuesday, January 16 after testing positive for Equine Herpes Virus (EHV-1). The horse was originally transported to the facility for an unrelated medical issue. The horse began displaying neurological symptoms on January 14.
According to MDA, the Baltimore County farm of origin is presently under a 21-day investigational hold and strict biosecurity measures are in place while Maryland Department of Agriculture inspectors perform additional epidemiological and infectious disease testing. The Maryland and Pennsylvania Departments of Agriculture are working with the University of Pennsylvania to establish and notify epidemiologic links to the sick horse.
Owners are cautioned to monitor horses at their premises carefully, and should contact their private veterinarians to arrange for Equine Herpes Virus testing if a horse exhibits significant temperature elevations or neurologic signs. Veterinarians are required to report equine neurologic syndrome to the department.
