EHM is the often deadly neurologic form of the Equine Herpes Virus infection.
No recent movement had occurred at the farm where the virus was reported prior to this case. The horse was moved into the isolation barn at a local animal hospital the evening EHM was confirmed.
Both the horses at the original farm and the hospital are under quarantine.
Nine horses were being treated at the hospital at the time of the incident; several horses were exposed to the ill horse.
The EHV-1 organism spreads quickly from horse to horse and can cause respiratory problems, especially in young horses, spontaneous abortions in pregnant mares, and the neurologic form of the virus can result in death.
Concerned owners should consult with their veterinarian prior to taking any action as the clinical signs of infection with the neurological form of EHV-1 are common to many other diseases.
