Influenza in Canada. 1994-1995 season.

From October each year to the following May, the Laboratory Centre for Disease Control (LCDC) maintains a program for the national surveillance of influenza. This program is supported by a number of laboratories and provincial and territorial epidemiologists who collaborate by exchanging information on cases, laboratory identifications and outbreaks. During the 1994-1995 season these surveillance activities included the collection of weekly aggregated reports of virus identifications by laboratories via an interactive voice response (IVR) system. Participating laboratories submitted detailed case-by-case reports of laboratory-confirmed infections and provincial and territorial health departments provided weekly assessments of influenza-like illness activity in the community.
