Human cases of West Nile virus in Canada, 2015
Source: Public Health Agency of Canada. Surveillance of West Nile virus.
During the West Nile virus season (mid-April to October), Canada conducts ongoing human case surveillance across the country. Monitoring West Nile virus nationally is a joint effort between the Government and its partners, including provincial and territorial ministries of health, First Nations authorities and blood supply agencies.
The Government relies on the provinces and territories to report the number of West Nile virus cases. To accurately reflect the annual occurrence of West Nile virus cases in Canada, health professionals need to remain vigilant in diagnosing West Nile virus, and reporting cases to their public health regional authorities. Case definitions can be accessed at: National Surveillance for West Nile virus.
