Severe Acute Respiratory Syndrome Coronavirus 2 Vertical Transmission from an Asymptomatic Mother.

In utero transmission of severe acute respiratory syndrome coronavirus 2 infection is a point of debate. We report a case of severe acute respiratory syndrome coronavirus 2 vertical transmission from asymptomatic mother, with molecular detection in mother's blood at delivery and neonatal nasopharyngeal swabs at 5 and 28 hours of life and later IgG seroconversion. The newborn was asymptomatic.
