What Is the Incidence of Nosocomial COVID-19?

摘要

With rigorous infection control measures implemented, nosocomial COVID-19 is a rare event. During the height of the pandemic in Boston, hundreds of patients were admitted to hospitals for COVID-19. Investigators studied patients at one Boston hospital who were diagnosed with COVID-19 on hospital day 3 or later or within 14 days after discharge to assess the risk for nosocomial acquisition of SARS-CoV-2. Measures implemented for infection control evolved over time but included screening for symptoms; testing for SARS-CoV-2; dedicated COVID-19 units with airborne isolation rooms; personal protective equipment; universal masking of staff and, later, patients; and visitor restriction.
