Equine herpes virus 1 has been found in a horse near Saskatoon.
Most horses are exposed to the common equine virus.
It usually causes mild respiratory disease, but in some cases the virus can spread to other body parts.
The virus can cause abortions in pregnant mares and in rare cases it can affect the nervous system.
EHV-1 is not transmissible to humans and most animal species, but it is very contagious among horses and camelids such as llamas and alpacas.
It is usually spread between animals in close quarters such as stables. It can also occur with indirect contact such as sharing contaminated equipment or other inadequate hygiene procedures, as well as aerosol transmission such as coughing.
The sick horse is being boarded at a stable, which is under voluntary quarantine.
Clinicians from the Western College of Veterinary Medicine at the University of Saskatchewan are monitoring the situation.
