Surveillance

Surveillance for West Nile Virus in Canada is done to detect the presence of the virus as early as possible in any given area in order to protect the community and reduce their risk of infection. Surveillance activities will vary by region depending on the previous West Nile Virus cases seen in the region. Surveillance activities will focus on mosquitoes, birds, horses and humans.
