2009 Surveillance Data
There are three parts to the West Nile Virus program in B.C.: Communications/Education, Mosquito Control and Surveillance.
Dead birds belonging to the corvid family (ravens, crows, magpies and jays [jays include Steller's jay, grey jay, blue jay and Clark's nutcracker]) that are found and called in are sent for testing to the Animal Health Centre in Abbotsford, B.C. They are tested for the West Nile Virus.
Mosquitoes are trapped in a number of locations along the southern part of the province, and sent in to BCCDC for identification. Mosquitoes identified as Culex pipiens and Cx. tarsalis are tested for the virus.
Finally, dead corvids that are not suitable for testing, or cannot be picked up can be reported online.
