West Nile Virus Equine Surveillance 2003
West Nile virus (WNv) is an Immediately Notifiable Disease under the federal Health of Animals Act. Diagnostic laboratories are required to report details of suspected or confirmed cases of WNv to the Canadian Food Inspection Agency (CFIA). The Ontario Ministry of Agriculture and Food works with the CFIA, Health Canada and private laboratories in the collection and presentation of Ontario equine case data as part of the provincial West Nile virus surveillance, led by the Ministry of Health and Long-Term Care.
*Note - Health Canada and the CFIA are reporting all positive
test results for WNv, not just confirmed or probable cases. Most
of the positive tests to date have been attributed to vaccination
or infections from 2002. OMAF will only be reporting those cases
considered to be new infections, based on the presence of clinical
signs and/or the appropriate laboratory diagnosis.
Total: 9 confirmed
Location of cases for which information is available:
* possibly acquired outside of Ontario
