SARS‐CoV‐2 infection as cause of in‐utero fetal death: regional multicenter cohort study
ABSTRACT Objective Placental infection with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) can lead to placental insufficiency and in‐utero fetal death (IUFD). The objective of this study was to confirm and quantify the extent to which fetoplacental infection with SARS‐CoV‐2 is a cause of fetal death.
