West Nile virus 2004 : Equine Surveillance
Information about equine (horse) surveillance in Ontario
The Ontario Ministry of Agriculture and Food provides the most current data on WNv infection in horses. WNv infection in horses often occurs concurrently, or sometimes just prior to, human infection. Due to the high intensity of mosquito exposure frequently experienced by horses, equine surveillance may be important, particularly in rural settings, as an indicator of West Nile virus activity and of human risk. However, the fact that the cost of testing is usually borne by the horse owner together with the increasing vaccination of horses against WNv infection may limit the usefulness of equine surveillance. Equine Vaccine
An equine vaccination product is available from veterinary practitioners in North America. The Ontario Ministry of Agriculture and Food promotes the WNv vaccination of horses to veterinarians and the equine industry in Ontario. Equine practitioners can send serum or tissue samples to the Animal Health Laboratory in Guelph, or to other private veterinary diagnostic laboratories for analysis. While there is no federal policy for action on equine WNv, laboratories must notify the Canadian Food Inspection Agency of any positive test result for equine WNv. Surveillance Statistics
