Canadian SARS-CoV-2 serological survey using antenatal serum samples: a retrospective seroprevalence study.

ABSTRACT:

Background

Insufficient data on the rate and distribution of SARS-CoV-2 infection in Canada has presented a substantial challenge to the public health response to the COVID-19 pandemic.
