The management of mother-infant dyads during the ongoing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic constitutes a major issue for neonatologists.
In mothers with SARS-CoV-2 infection, current recommendations suggest either to separate the dyad or encourage protected rooming-in under appropriate precautions.
No data are available regarding the risk of mother-to-infant transmission of SARS-CoV-2 during rooming-in.
We evaluate the risk of postnatal transmission of SARS-CoV-2 from infected mothers to their neonates following rooming-in and breastfeeding.
A prospective, multicenter study enrolling mother-infant dyads from March 19 to May 2, 2020, followed up for 20 days of life (range, 18-22 days), was performed. The study was conducted at 6 coronavirus disease 2019 maternity centers in Lombardy, Northern Italy.
