The Utah State Veterinarian has confirmed a case of neurologic equine herpesvirus in Davis County. Two other horses are suspected of having the virus and 100 other horses have been exposed. The confirmed positive horse was euthanized after it became recumbent.

The horse confirmed with neurologic equine herpesvirus (also known as equine herpesvirus myeloencephalopathy or EHM) was at Weber County Complex eight days prior to becoming sick. 

Events at the Weber County Complex have been cancelled for the next two weeks. 

Two horses previously at the Weber County Complex have fevers and are being tested for EHV-1. The two suspect cases are quarantined at separate facilities.
