The coronavirus disease 2019 (COVID-19) pandemic caused significant mortalities in the adult population in New York City. Pregnant women at late gestational age positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) showed mild symptoms compared with nonpregnant adults. Rare cases of newborn babies testing positive for the SARS-CoV-2 virus within the first 24 hours have been reported. 1,2 Miscarriages in second trimesters were also reported related to maternal COVID-19. 3 Placental pathology has been studied in small case series with controversial results, and vertical transmission was reported in some cases. 4e6 We sought to examine the placental pathology and to localize the SARS-CoV-2 viral particles within the placental tissue.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
