Universal screening for SARS-CoV-2 in asymptomatic obstetric patients in Tokyo, Japan

Retrospective review of 52 pregnant women universally tested for SARS-CoV-2 admitted to a single hospital in Tokyo. Of the 52 women, none presented with symptoms of COVID-19, yet two (3.8%) were confirmed positive when tested using PCR. For these patients, elective cesarean deliveries were performed in negative-pressure operation rooms followed by postpartum care in isolation rooms. The patients remained asymptomatic, with subsequent repeated negative PCR results. The newborns were admitted to the NICU isolation area with negative ventilation; none tested positive for SARS-CoV-2 after birth.
