1993-1994 influenza season: Canadian laboratory diagnoses, strain characterization and post-season serosurvey (Ontario).
In Canada as a whole, influenza A/Beijing/32/92-like virus was the dominant infecting strain in the 1993-1994 season with reported laboratory diagnoses peaking in January 1994. Vaccination is again urged for all persons in high-risk groups. Antibody induced by vaccination does not persist well from season to season and the emerging A/Shangdong/9/93 (H3N2)-like variant is related to A/Beijing/32/92(H3N2) but is inhibited less by antibodies to that strain. Conditions are also consistent with possible increased influenza B activity this season.
