Objectives Report of clinical data on maternal outcomes, mode of delivery and immediate neonatal outcome in women infected with COVID-19, as well as clarifying whether the transmission of SARS-CoV-2 could occur in utero (congenital), intrapartum, and/or postnatally through breastmilk, amniotic fluid or cord blood. Methods Retrospective data collection. Evidence of vertical transmission was assessed by testing for SARS-CoV-2 in amniotic fluid, cord blood, maternal liquor, breast milk and neonatal pharyngeal swab samples. Results 8.9% (n=8) of the total population of hospitalized SARS-CoV-2 positive pregnant women were admitted to a critical care unit, one (0.9%) needed extracorporal membrane oxygenation (ECMO) and one woman died (0.9%). The premature birth rate before 34+0 weeks of gestational age of 8.2% (n=8) among pregnant women who tested positive for SARS-CoV-2, was almost four times higher than among the total population of pregnant women in Austria. Two newborns (2%) were tested positive for SARS-CoV-2 after birth. No SARS-CoV-2 was found in amniotic fluid, cord blood, maternal liquor or breast milk using polymerase chain reaction (PCR). Conclusions Pregnant women with COVID-19 seem to be at a higher risk of invasive ventilation, admission to a critical care unit and pre-term birth and therefore they should be considered as a high-risk population. The risk of congenital or intrapartal infection seems to be insignificant.
