Canadian COVID-19 Antibody and Health Survey, Cycle 1

The first part is an electronic questionnaire about general health and exposure to COVID-19. The second part is an at-home finger-prick blood test, which is sent to a lab to determine the presence of COVID-19 antibodies.

The data will be used to: estimate how many Canadians test positive for antibodies even if they have never had symptoms of COVID-19 better understand the social distancing behaviours of Canadians and their general health during the pandemic. This important information will help evaluate the extent of the health status associated with the COVID-19 pandemic such as the prevalence of infection even for people who have never had symptoms, among a representative sample of Canadians.
