Equine Herpes Virus (EHV-1) infection in horses can cause respiratory disease, abortion in mares, neonatal foal death, and/or neurologic disease. The neurologic form of EHV-1 is called Equine Herpes Virus Myeloencephalopathy (EHM).
Transmission likely occurs by inhaling infected droplets or ingesting material contaminated by nasal discharges or aborted fetuses. Clinical symptoms may include a fever, difficulty urinating, depression, and stumbling or weakness in the hind limbs. Supportive therapy is often used to treat these cases. In severe cases, horses will be unable to stand; these cases have a very poor prognosis. EHV-1 is not transmissible to humans.

State Veterinarian Richard Wilkes, D.V.M., today released the quarantine on the Fauquier County facility.
March 8, 2016
No horses at the training facility in Virginia currently under quarantine for EHM have shown signs of neurologic disease. Temperatures and health will continue to be monitored twice daily during the quarantine period.
March 3, 2016
There are twelve horses currently under quarantine at the training facility. An epidemiological investigation revealed no other horses were exposed in Virginia. All horses under quarantine will be monitored for clinical signs compatible with EHM. Any horse that shows signs will be tested for EHV-1. If a horse shows clinical signs and tests positive the length of quarantine will be extended.
