In a sample of 598 hospitalized pregnant women with COVID-19, 55% had no symptoms on admission, according to a report released this week by the Centers for Disease Control and Prevention.
Among the 272 women with COVID-19 symptoms, 44 were admitted to an intensive care unit, 23 received mechanical ventilation and two died, the authors said. About 98% of all the pregnancies completed during hospitalization resulted in live births.
In a separate CDC study of 105 hospitalized pregnant women with the SARS-CoV-2 virus, 41% were admitted for COVID-19 illness and the rest for obstetric reasons. About 80% of those admitted for obstetric reasons were asymptomatic.
