Five EHV-1 cases confirmed at Canadian racetrack

Horses carrying EHV may appear to be perfectly healthy yet spread the virus via the secretions from their nostrils.

Horses carrying EHV may appear to be perfectly healthy yet spread the virus via the secretions from their nostrils.

Five cases of the neurological form of equine herpes virus-1 (EHV-1) have been confirmed in thoroughbreds in Barn 1 at Woodbine Racetrack, the Ontario Racing Commission says.

One horse was euthanized on June 10 after becoming recumbent with a fever. A second horse in the same barn also had a fever and showed neurological signs.

The second horse was taken to the Ontario Veterinary College for further evaluation and treatment.

Thoroughbred racing will continue at Woodbine. However, due to the infectious nature of this disease, the commission has ordered the implementation of various infectious disease protocols to protect horses.

No horses are permitted to leave Woodbine Racetrack without the commission’s approval for the next seven days. The restriction may be reviewed based on the progression of the disease.

In addition, no horse is allowed in or out of Barn 1 or Barn 3 for the next 7 days, including for training. This restriction may also be reviewed, based on the progression of the disease.

All horses stabled at Woodbine must have their temperatures taken and recorded visibly on the horse’s stall door for inspection. Trainers with horses that have clinical signs consistent with EHV-1 infection, including a fever and respiratory or neurological signs, must report their findings to their veterinarian immediately.

Horse people who had horses at Woodbine Racetrack within the last seven days should monitor their horses for any signs of illness, the commission says.

It said it would continue to closely monitor the situation and any further developments will be reported.
