Key message

A transmissão de SARS-CoV-2 in utero parece ser possível, como sugere a presença de IgM numa recém-nascida com 2 horas de vida. São necessários outras análises de amostras da mãe e da nascitura para confirmar esta observação preliminar.

Abstract

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is highly infectious, with multiple possible routes of transmission. Controversy exists regarding whether SARS-CoV-2 can be transmitted in utero from an infected mother to her infant before birth. A series of 9 pregnant women found no mother-child transmission. We report a newborn with elevated IgM antibodies to SARS-CoV-2 born to a mother with coronavirus disease 2019 (COVID-19).
