... rns. Study Design: We conducted literature search for case series and case reports about pregnancy outcomes in pregnant women with COVID-19 during the early phase of pandemic. Results: In case series, 37 of 129(28.6%) pregnant women with COVID-19 disease had preterm delivery and 14 of 67 pregnant women had fetal distress.
