Canada heading for flu season in the middle of fourth wave of COVID-19
OTTAWA — The country could be heading for its first typical flu season since the pandemic began, even as health systems are still battling the fourth wave of COVID-19, Canada’s top doctor warns.
Last year the flu was “virtually non-existent,” in Canada, thanks to strict public health measures to protect against COVID-19, chief public health officer Dr. Theresa Tam said Friday.
What served as a blessing last fall, sparing already overwhelmed health systems, could now mean Canadians have less immunity against common strains of the flu.
Surveillance data from the Public Health Agency of Canada shows higher rates of infection than expected for some of Canada’s most common seasonal viruses: respiratory syncytial virus, or RSV. and human parainfluenza.
