Third‐trimester placentas of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2)‐positive women: histomorphology, including viral immunohistochemistry and <i>in‐situ</i> hybridization

Abstract

In this study, third-trimester placentas from SARS-CoV-2-positive women were more likely to show evidence of maternal-fetal vascular malperfusion; however, ISH and IHC provided no evidence of direct viral involvement or vertical transmission.
