Kentucky Department of Agriculture officials quarantined an equine facility in Oldham County. Tests confirm that multiple horses are positive for the neurologic form of the equine herpes virus (EHV-1).
A veterinarian notified the KDA after noticing urine dripping in a 2-year-old filly on January 4th. Tests confirmed the horse was positive for the neuropathogenic strain of EHV-1. Officials report the horse continues to improve.
KDA quarantined the index equine facility. Veterinarians tested another 14 horses stabled in the same wing as the neurologic horse, as well as three horses that were preparing to ship.
Two days later, a horse in Wing 2 spiked a fever over 103 degrees. Veterinarians collected nasal swabs and whole blood from the animal. The lab reported two of the 14 horses and the horse with the fever were also positive for the neuropathogenic strain of EHV-1, which is also known as equine myeloencephalopathy (EHM).
Vets expect test results for the remaining 18 horses on Monday.
KDA located all horses moved from the index facility since mid-December. They are assessing and testing the horses, following KDA’s protocol. No horses have been moved to any Kentucky racing or training facility.
Two horses that left the facility in late December traveled to an out of state track. Officials have located the horses, isolated them, and submitted their samples for testing.
An outbreak of EHV-1 continues at the Fair Grounds Race Course in Louisiana with the count at 14 confirmed cases after the weekend.
Kentucky is not allowing any horses that have been at a Louisiana racetrack or training center since December 10 onto any Kentucky track.
