The findings of this study provide evidence of possible vertical transmission of severe acute respiratory sydrome coronavirus 2 (SARS-CoV-2) in asymptomatic pregnant women, using the novel World Health Organizaton criteria for the establishment of mother-to-child transmission of SARS-CoV-2. The presence of SARS-CoV-2 RNA in amniotic fluid and its persistence in the neonate 24 h after birth was demonstrated.
What are the clinical implications of this work?This work highlights the importance of testing more than one sample for SARS-CoV-2 in neonates of asymptomatic infected women in order to increase the detection rate in positive cases. Identification of neonatal SARS-CoV-2 infection might help clinicians to understand better the long-term effects or complications of the disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
