Initial and 5-day positivity rate of severe acute respiratory coronavirus virus 2 (SARS-CoV-2) polymerase chain reaction (PCR) in exposed inpatients within shared rooms during the omicron-variant dominant period

초록

In this observational study conducted in 2022, 12.3% of patients who shared a room with a patient positive for severe acute respiratory coronavirus virus 2 (SARS-CoV-2) also had a positive polymerase chain reaction (PCR) test, either at initial screening or during a 5-day quarantine. Therefore, screening and quarantine are still necessary within hospitals for close-contact inpatients during the SARS-CoV-2 omicron-variant dominant period.
