Perinatal transmission with SARS-CoV-2 and route of pregnancy termination: a narrative review.

Objective: Analyze newborns diagnosed with SARS-CoV-2 performed with RT-PCR at birth or during the first days of birth and to look for an association with the route of birth.

Methods: We conducted a comprehensive literature search for newborns diagnosed with COVID-19 using PubMed, LILACS and Google scholar until May 15, 2020, looking for published articles with pregnancy, vertical transmission, intrauterine transmission, neonates, delivery.

Results: There were found 10 articles with a total of 15 newborn infected with SARS-CoV-2 according to positive PCR at birth or in the first days of birth. Eleven newborn birth by cesarean section and 4 vaginally. Of the 11 cases with cesarean section, two presented premature rupture of the membranes. Seven newborns developed pneumonia, of which two had ruptured membranes and one was born by vaginal delivery.

Conclusion: This review shows that there is perinatal or neonatal infection with SARS-CoV-2 by finding a positive PCR in the first days of birth. In addition, that there is more possibility of neonatal infection if the birth is vaginal or if there is premature rupture of the membranes before cesarean section. Vaginal delivery and premature rupture of membranes should be considered as risk factors for perinatal infection.
