Physicians should pay attention to asymptomatic patients to prevent nosocomial infections. PCR test results were confifrmed in all patients prior to admission, except for two who were in labor before testing. The two patients were isolated and treated in negative-pressure rooms until results confifrmed them negative. Of the 52 women, none presented with symptoms of COVID-19, yet two (3.8%) were confifrmed positive when tested using PCR, and one (1.9%) was treated as positive due to close contact with her COVID-19-confifrmed husband. For these patients, we performed elective cesarean deliveries in negative-pressure operation rooms ater obtaining informed consent, 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 ater birth (Table 1 ).
