Officials confirm a Pennsylvania horse tested positive for neuropathogenic equine herpesvirus-1 (EHV-1.)
The equine located in Unionville was exposed to a steeplechase horse in Virginia that was infected with equine herpesvirus myeloencephalopathy (EHM) — a neurological disease caused by EHV-1. The index horse was euthanized in early April.
Two of the three Pennsylvania horses that came in contact with the Virginia horse were euthanized at the owner’s request, according to Viriginia officials. The third remains under quarantine.
Pennsylvania farms with horses exposed to the Virginia index horse or have contained exposed horses, are under quarantine.
The index farm horses remain healthy in The Plains. The quarantine will be lifted on May 8th if there continue to be no clinical signs of the disease.
Symptoms include fever, decreased coordination, nasal discharge, urine dribbling, loss of tail tone, hind limb weakness, leaning against a wall or fence to maintain balance, lethargy, and the inability to rise. While there is no cure, the symptoms of the disease may be treatable. EHV-1 is not transmissible to people; it can be a serious disease of horses that can cause respiratory, neurologic disease and death.
