Federal modelling warns of fourth COVID wave driven by Delta if reopening is too fast
Federal officials are warning that Canada could be on the brink of a fourth wave of COVID-19 driven by the highly contagious Delta variant if the country opens too fast before enough people have been vaccinated.
Canada’s chief public health officer says long-term forecasts indicate that a hasty approach to reopening could portend a sharp resurgence of the virus by the end of the summer.
Dr. Theresa Tam says the new modelling underscores the need for caution in lifting public health measures as early signs of epidemic growth emerge in some areas.
Tam says officials expect that the Delta variant could fuel the spread of the virus among younger unvaccinated people, leading to a serious rise of case counts and hospitalization rates this fall and winter.
