The State Veterinarian’s Office confirmed on Tuesday that an Amelia County horse has tested positive for equine herpesvirus-1 (EHV-1), the virus that causes equine herpes myeloencephalopathy.

The horse is receiving medical care and is stable. The boarding stable has been placed under quarantine. All exposed horses on the farm are being monitored twice daily for fever (temperature over 101.5 F) and other clinical signs.

No additional Virginia horses have been exposed.

There is no cause for alarm concerning the general horse population in Virginia. EHV-1 is a virus that is present in the environment and found in most horses all over the world. Horses typically are exposed to the virus at a young age with no serious side effects.

A large percent of horses carry the virus with no clinical signs for the remainder of their lives. Rarely, exposed horses develop the neurologic form of the disease. Horse owners with concerns should contact their veterinarian.
