Course: Assessment of the Burden of SARS-CoV-2 Variants of Concern Among Essential Workers in the Greater Toronto Area, Canada

CME Credits: 1.00

Released: 2021-10-19

Variants of concern (VOC) of SARS-CoV-2 emerged toward the end of 2020. These resulted in documented replacement of wildtype SARS-CoV-2, with concerns of transmissibility, virulence, and immune escape, and were subsequently classified by an alphabetical system by the World Health Organization. Prior to the emergence of VOC, across countries, SARS-CoV-2 transmission and COVID-19 were disproportionately concentrated in neighborhoods of low socioeconomic status, which are characterized by a larger proportion of frontline essential workers, and higher density contact networks., We created a retrospective cohort of neighborhoods in the City of Toronto and Region of Peel, two of the most populous and most affected per capita regions of Ontario, stratified by income and essential work status, and noted the emergence of VOC through this population.
