IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca

IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.

AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.

Importance: 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. Objective: To evaluate the risk of postnatal transmission of SARS-CoV-2 from infected mothers to their neonates following rooming-in and breastfeeding. Design, setting, and participants: 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. Participants included 62 neonates born to 61 mothers with SARS-CoV-2 infection who were eligible for rooming-in practice based on the clinical condition of the mother and infants whose results of nasopharyngeal swabs were negative at birth. Exposures: Mothers with SARS-CoV-2 infection were encouraged to practice rooming-in and breastfeeding under a standardized protocol to minimize the risk of viral transmission. Main outcomes and measures: Clinical characteristics and real-time reverse transcriptase-polymerase chain reaction for SARS-CoV-2 on neonatal nasopharyngeal swabs at 0, 7, and 20 days of life. Results: Of the 62 neonates enrolled (25 boys), born to 61 mothers (median age, 32 years; interquartile range, 28-36 years), only 1 infant (1.6%; 95% CI, 0%-8.7%) was diagnosed as having SARS-CoV-2 infection at postbirth checks. In that case, rooming-in was interrupted on day 5 of life because of severe worsening of the mother's clinical condition. The neonate became positive for the virus on day 7 of life and developed transient mild dyspnea. Ninety-five percent of the neonates enrolled were breastfed. Conclusions and relevance: The findings of this cohort study provide evidence-based information on the management of mother-infant dyads in case of SARS-CoV-2 maternal infection suggesting that rooming-in and breastfeeding can be practiced in women who are able to care for their infants.
