Obstetric and perinatal variables were collected in a data sheet on admission to the emergency room and hospitalization. Results: Rapid test for SARS-CoV-2 was performed in 108 pregnant women hospitalized for delivery, 106 singleton pregnancies (98%) and 2 twins

deliveries were vaginal, 18,5% of them preterm; 37% of the pregnant women were symptomatic and 7,4% were admitted to the intensive care unit. 91,8% of the newborns weighed between 2500 and 3999g, 51% were female, 93,5 % had Apgar greater than 7 at one minute and 100% with negative swabbing in newborns within the first 24 to 72 hours. Conclusion: Most of the pregnant women were asymptomatic and 3 out of 100 pregnant women had respiratory
complications. The prevalence of cesarean section was low in relation to other publications, 2 of the newborns had positive swabs with possible horizontal transmission.
