haracterization of neonates born to mothers with SARS-CoV-2 infection has been partially carried out.

There has been no systematic review providing a holistic neonatal presentation including possible vertical transmission. A systematic literature search was performed using PubMed, Google Scholar and Web of Science up to June, 6 2020.

Studies on neonates born to mothers with SARS-CoV-2 infection were included.

A binary random effect model was used for prevalence and 95% confidence interval.

32 studies involving 261 neonates were included in meta-analysis. Most neonates born to infected mothers did not show any clinical abnormalities (80.4%). Clinical features were dyspnea in 11 (42.3%) and fever in 9 newborns (19.1%).

Of 261 neonates, 120 neonates were tested for infection, of whom 12 (10.0%) tested positive. Swabs from placenta, cord blood and vaginal secretion were negative.

Neonates are mostly non affected by the mother's SARS-CoV-2 infection. The risk of vertical transmission is low.
