SARS-CoV-2 infection in pregnant women and newborns in two maternity hospitals in Salvador-Bahia, Brazil.

The outbreak of the new coronavirus (SARS-CoV-2) causing the coronavirus disease (COVID-19) has spread globally. As of June 18, 2020, a high maternal mortality rate due to SARS-CoV-2 infections was identified in Brazil, representing most of the world cases at that time. An observational, cross-sectional study was performed with pregnant women admitted in two maternity hospitals located in Salvador/Bahia and their newborns, from May 24th up to July 17th of 2020. Among 329 pregnant women enrolled at hospital admission, a high prevalence (n=28; 8.5%) of pregnant women with COVID-19 was observed, as well as a high proportion of asymptomatic cases (n=19; 67.9%). Two newborns had detectable SARS-CoV-2 but evolved without abnormalities. This data highlight the importance of identifying pregnant women with COVID-19 for proper isolation measures to prevent in-hospital transmission.
