Sociodemographic characteristics of SARS-CoV-2 serosurveillance studies with diverse recruitment strategies, Canada, 2020 to 2023
Using data from 25,156 CanPath participants, Matthew J. Knight and colleagues investigated the general population representation of serology investigations conducted in Canada. Racialized groups were frequently underrepresented, they discovered, especially in conventional cohort-based studies such as CanPath. The study demonstrates that no one recruiting strategy is completely representative, underscoring the necessity for several approaches in national health surveillance, even though other strategies were able to capture greater variety among rural and low-income individuals.
