Epidemiology, Management and Risk of Sars-Cov2 Transmission in a Cohort of Newborns Born to Mothers Diagnosed with Covid19 Infection

ABSTRACT

INTRODUCTION: the impact of maternal SARS-CoV2 infection and its risk of vertical transmission is still not well known. Recommendations from scientific societies seek to provide safety for newborns without compromising the benefits of early contact. The aim of the study is to describe characteristics and evolution of newborns born to mothers with SARS-CoV2 infection, as well as the implemented measures following recommendations from the Sociedad Espanola de Neonatologia. METHODS: observational, prospective and single-center cohort study. A specific circuit was designed for mothers with SARS-CoV2 infection and their newborns. Epidemiological and clinical data were collected. PCR were performed in newborns at delivery and at 14 days of age. RESULTS: 73 mothers and 75 newborns were included in the study. 95.9% of maternal infections were diagnosed during the third trimester of pregnancy, 43.8% were asymptomatic. Median gestational age was 38 weeks (IQR37-40), 25.9% of newborns required admission to Neonatology. Skin-to-skin mother care was performed in 68% of newborns, 80% received exclusive maternal or donated breast milk during hospital stay. No positive PCR results were observed in newborns at delivery, one case of positive PCR was observed in an asymptomatic neonate at 14 days of age. CONCLUSIONS: Risk of SARS-CoV2 transmission is low when complying to the recommendations issued by Sociedad Espanola de Neonatologia, allowing rooming-in and promoting breastfeeding.
