BACKGROUND
The effects of the novel coronavirus disease 2019 (COVID-19) in pregnancy remain relatively unknown. We present a case of second trimester pregnancy with symptomatic COVID-19 complicated by severe preeclampsia and placental abruption.
METHODS
We analyzed the placenta for the presence of severe acute respiratory syndrome coronavirus 2 (SARS–CoV-2) through molecular and immunohistochemical assays and by and electron microscopy and measured the maternal antibody response in the blood to this infection.
RESULTS
SARS–CoV-2 localized predominantly to syncytiotrophoblast cells at the materno-fetal interface of the placenta. Histological examination of the placenta revealed a dense macrophage infiltrate, but no evidence for the vasculopathy typically associated with preeclampsia.
CONCLUSION
This case demonstrates SARS–CoV-2 invasion of the placenta, highlighting the potential for severe morbidity among pregnant women with COVID-19.
