Weekly influenza reports

May 23, 2021 to June 19, 2021 (weeks 21-24)

• Despite continued monitoring for influenza across Canada, there has been no evidence of community circulation of influenza during the usual period of seasonal influenza activity from mid-November to mid-April. Given the time of year, influenza is expected to remain at interseasonal levels for the remainder of the 2020-2021 seasonal influenza surveillance period.
