COVID Symptoms, Seroprevalence, and Mortality During the First Wave of SARS-CoV-2 in Canada

A large group of researchers found seroprevalence across Canada was low in the first wave of the pandemic but found 31% of those who tested positive for antibodies had never had symptoms. They also found the death rate in nursing homes was over 70 times greater than among elderly adults living outside of nursing homes.

Canadian Blood Services and the CITF’s collaborative nine-province SARS-CoV-2 seroprevalence study for October thru November suggests that 1.5 per cent of healthy Canadians had been exposed to SARS-CoV-2. The highest levels were recorded in Western Canada but mass national vaccination remains only route to achieving herd immunity.

Final results of initial Canadian SARS-CoV-2 seroprevalence study announced

Study suggests as few as 0.7% of adults have antibodies to SARS-CoV-2 Canadian Blood Services and Canada’s COVID-19 Immunity Task Force (CITF) are releasing final results of a collaborative nine-province SARS-CoV-2 seroprevalence study. This analysis, based on 37,373 blood samples from blood donor centres across Canada (except Quebec and the Territories), reveals that fewer than 1 per [...]
