EQUINE HERPES VIRUS-1 IN SASKATCHEWAN

Saskatchewan horse owners are reminded to practice sound biosecurity measures, after the discovery of a case of the neurological form of Equine Herpes Virus in the province.

Equine Herpes Virus is a contagious disease in horses that causes respiratory failure, abortions in mares and, in some cases, neurological (brain and spinal cord) disease. In recent years a new, more severe strain of the virus has emerged in North America, called neurotropic Equine Herpes Virus-1 (nEHV-1). This virus poses no human health risk.

On May 30, a horse in the Moosomin area tested positive for nEHV-1 virus. This horse attended the Lloydminster cutting horse show on May 14 and 15. It is believed that this case is associated with an outbreak of the same virus in the Western United States.

nEHV-1 can be spread between horses through the nasal secretions of infected horses and can also be transferred indirectly by people and equipment.

"nEHV-1 is very serious in horses, and we are responding accordingly," Saskatchewan Chief Veterinary Officer Greg Douglas said. "We want to ensure that all horse owners are made aware of the situation and take proper precautions in response to this news."

Saskatchewan horse owners are encouraged to remain vigilant about protecting their horse's health by maintaining good biosecurity practices. In addition, any horse that has been in contact with high risk horses should be monitored closely for signs of respiratory or neurological disease. Any horse showing signs of neurological or respiratory disease should be examined by a veterinarian.

To avoid spreading nEHV-1, direct and indirect contact with sick and high risk horses should be avoided. Horses that attended the Lloydminster cutting horse show are considered to be at high risk for nEHV-1 infection. All horses present at this show should be isolated for a period of 28 days after the show. Furthermore, all horses that have been in contact with horses present at the Lloydminster show should also be isolated for 28 days.

Horses can be infected with nEHV-1 and not show any clinical signs, but still shed the virus and infect other horses.

Horse owners are encouraged to contact their local veterinarian to discuss any concerns they may have regarding nEHV-1.
