Course: Estimates of SARS-CoV-2 Omicron Variant Severity in Ontario, Canada

CME Credits: 1.00

Released: 2022-02-17

The World Health Organization designated Omicron as a variant of concern on November 26, 2021. Omicron has 37 mutations in the spike protein and has rapidly replaced Delta as the dominant variant globally, due to increased immune evasion. It is less clear how the severity of Omicron compares with that of Delta. Early data from South Africa suggest that Omicron may be less severe than prior lineages; however, the low average age of infected individuals, extent of previous infection, and low vaccination rates affect generalizability to certain other countries. In Ontario, Canada, we examined hospitalizations and deaths associated with Omicron compared with matched patients infected with Delta.
