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, 2018 after testing positive for Equine Herpes Virus (EHV-1). Epidemiology on the EHM positive horse that was transported to New Bolton Center in Kennett Square, Pennsylvania has confirmed that the horse originated from a farm in Baltimore Maryland. The horse was euthanized at the University of Pennsylvania’s New Bolton Center on Tuesday, January 16, 2018 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, 2018.
