Course: Association of Omicron vs Wild-type SARS-CoV-2 Variants With Hospital-Onset SARS-CoV-2 Infections in a US Regional Hospital System
CME Credits: 1.00
Released: 2022-06-15
The SARS-CoV-2 Omicron variant is more contagious than prior variants, leading to large increases in community cases. Little is known, however, about the incidence of nosocomial SARS-CoV-2 infections with Omicron vs prior variants.
We retrospectively identified all SARS-CoV-2 cases diagnosed in 12 hospitals within the Mass General Brigham health care system between July 1, 2020, and February 28, 2022. All patients were tested on admission with polymerase chain reaction (PCR) assays, and, starting November 2020, were retested 72 hours after admission to identify cases with virus incubating on admission. Retesting was also required for new symptoms, after possible exposures, before aerosol-generating procedures, and before discharge if requested by destination facilities.
