Is Vertical Transmission of SARS-CoV-2 Infection Possible in Preterm Triplet Pregnancy? A Case Series.

There is limited data regarding the vertical transmission (VT) of severe acute respiratory syndrome-coronavirus-2 infection. We report the first case of VT in preterm triplet pregnancy, with all triplets positive for severe acute respiratory syndrome-coronavirus-2 at 20 hours and day 5 of life. This report reiterates the need for an expedited formulation of a simple, standardized, and reproducible international case definition and classification for VT.
