On April 14th, 2024, the Maryland Jockey Club was alerted to a horse displaying neurological abnormalities in its hind limbs. At that time, the horse did not exhibit a fever, and has remained without one since. As a precautionary measure, both this horse and another, which had been in close proximity to the affected animal but showed no symptoms, were relocated to an isolation barn at Laurel Park. Additionally, Barn 33, where the affected horse was housed, was promptly placed under quarantine.
We promptly notified the State Veterinarian's Office and arranged for the affected horse to undergo testing for Equine Herpesvirus (EHV). Late yesterday, we received confirmation that the initial nasal swab tested positive for EHV. Further testing is scheduled for later this week.
In collaboration with the State Veterinarian's Office, we are in the process of developing a comprehensive quarantine protocol for Barn 33. This plan will allow horses in this barn to train separately from the general population and enable other barns to continue their regular racing and training activities.
It is imperative that all horses stabled there are closely monitored for any signs of fever or symptoms consistent with EHV. Any horse registering a temperature above 101.5 degrees Fahrenheit or exhibiting signs of incoordination must be reported immediately to an MJC Veterinarian.
