The Oklahoma Department of Agriculture has confirmed 11 horses have tested positive for equine herpesvirus type 1 (EHV-1) at Remington Park racetrack. Only one 3-year-old filly was confirmed with the neurologic form of herpesvirus and was euthanized. 100 horses were exposed.
Two barns had been quarantined, and the first barn was released on December 5. The horses in that barn completes a 14-day quarantine with no exposure to an EHV-1-positive horse, no fevers, and no clinical signs compatible with EHV-1. They also had two negative tests a week apart.
One additional horse in the second quarantine barn tested PCR positive for EHV-1 and was moved to the isolation facility.
