The BC Centre for Disease Control (BCCDC) says the province is in the throes of a late-season wave of the flu.
The agency says the majority of the cases involve the influenza A strain, while occurrences of influenza B remain low overall.
The data, which comes from the BCCDC’s weekly flu surveillance reporting, found a 50 per cent jump in flu cases in the most recent three weeks tracked.
Since October, the agency says the vast majority of flu cases have been influenza A. About 76 per cent of them have been the H1N1 strain, but the BCCDC says in the last week 75 per cent of the cases have been of the H3N2 strain.
