Placental Barrier against COVID-19

Category: Article Summary

Topic: Transmission

• Komine-Aizawa et al. performed a narrative review summarizing evidence from pathological examinations of placental tissues in mothers with COVID-19, finding that these tissues are often infected with SARS-CoV-2 although fetuses are not always infected. They review potential mechanisms for SARS-CoV-2 vertical transmission. The authors conclude that although placentas are susceptible to SARS-CoV-2 infection, they may partially protect fetuses.
