IntroductionDue to growing evidence suggesting COVID-19 may have a benign course in the newborn, a number of guidelines supporting rooming-in and breastfeeding were developed. The main aim of the study was to assess the safety of this approach, through the risk of developing severe neonatal infection.Material And MethodsProspective observational study from April 2020 to February 2021 on the approach and neonatal follow-up of infants born to mothers with COVID-19 at the time of delivery in a hospital with advanced neonatal care, where rooming in and breastfeeding were promoted whenever possible. We collected data during hospital admission and over the phone during the neonatal period.ResultsWe included 77 infants born to mothers with COVID-19 (3.8% of newborns born during the time of study), median gestational age 39 weeks + 5 days and median birth weight 3270 g; 9% were born premature (versus 12% born premature among newborns born during the time of study). Rooming-in took place in all of them although 4% were briefly admitted to the Neonatal Intensive Care Unit; 88% were discharged home up to day three, 97% were breastfed at the time of discharge and 90% were still breastfed by the end of the neonatal period. We completed neonatal follow-up of 63 newborns, eight of them developed COVID-associated symptoms, three with need of medical evaluation; 40% had no medical assessment after being discharged. Out of 77, 5% of infants were infected with SARS-CoV-2 (total of four, one mild, three asymptomatic), with no significant differences during hospital stay or follow-up.DiscussionNeonatal infection was uncommon and mild, and there was no increase in prematurity. Rooming-in and breastfeeding were safe and should be promoted whenever clinically possible. Follow-up care after hospital discharge needs improvement.ConclusionInfants born to mothers with COVID-19 were safely roomed in with their mothers and exclusively breastfed.
