British Columbia is experiencing a second wave of flu due to an unusual late-season spread of the virus.
Most of the strains being reported are influenza A (H3N2), the BC Centre for Disease Control (BC CDC) said.
Levels of influenza B are “unusually low,” the centre added.
BC CDC data show a 50% surge in flu diagnoses over the last few weeks.
Case numbers peaked in early January and plummeted in February before a recent rise.
The centre explained: “It is too soon to know whether this second wave has peaked.”
