Re: Equine Herpes Virus-1


         The Kentucky Department of Agriculture has placed three barns (approximately 100 horses) at Churchill Downs under quarantine while awaiting definitive test results for Equine Herpes Virus. Only barns with horses exhibiting clinical signs are quarantined. Horses in the barns placed under quarantine are prohibited from moving in or out of those barns in an effort to contain the virus to those areas. The horses, at this point, are not allowed to train with the general horse population. These actions are in response to horses that exhibited neurological signs and fever. Two horses required euthanasia due to the severity of the neurological signs.


     Since February of 2005, several cases of Equine Herpes Virus Type 1 (EHV-1) were identified at Northville Downs in Michigan, Truro Raceway in Nova Scotia, Canada and the Meadows in Meadow Lands, Pennsylvania, an equine facility in Tioga County, NY, and Columbia Horse Center in Maryland. We recommend that horse owners and trainers, traveling to other facilities, request disease prevalence and all related requirements for those facilities prior to movement.


     The New York Racing Association (NYRA) has temporarily restricted entry onto NYRA premises of horses stabled at Churchill Downs. Trainers wishing to ship horses that have relocated from Churchill Downs since May 1st must first contact Dr. Celeste Kunz at (516) 204-5087.


     The New Jersey Department of Agriculture recommends:
  • Horses entering a training facility, racetrack, show-grounds, etc. should have written verification by a licensed/accredited veterinarian of equine herpes virus vaccination as recommended by the manufacturer.
  • Horses entering a training facility, racetrack, show-grounds, etc. should have a normal rectal temperature upon arrival.
  • Horses exhibiting neurological symptoms consistent with EHV must be reported to the New Jersey Department of Agriculture’s Division of Animal Health and should be tested and quarantined immediately.


     The New Jersey State Laboratory can evaluate serum samples and nasopharyngeal swabs for Equine Herpes Virus. If you have any further questions or concerns, contact us at (609) 292-3965.
