The flu may be at its worst in Canada since the COVID-19 pandemic. The Public Health Agency of Canada's Flu Watch report, released Friday, shows test positivity for influenza at 26.9 per cent and rising.
"Nationally, indicators of influenza activity continue to increase," according to the report . "The percentage of tests positive for influenza is now at its highest value since the start of the 2020-21 season." The agency's surveillance for influenza includes hospital-based data, weekly surveys of Canadians who are asked about new respiratory symptoms and people who test positive for flu when they seek medical care.
"Per cent positivity will be tracked over time to see when that peak happens and when the burdens are high," Dr. Zain Chagla, an infectious disease physician at St. Joseph's Healthcare and an associate professor at McMaster University in Hamilton, said on CBC's The Dose.
