A preprint, and unpublished, not peer reviewed report posted on MedRxiv, looked at placental infection with SARS-CoV-2.
Prof Marian Knight, Professor of Maternal and Child Population Health, University of Oxford, said:
“Pre-eclampsia is a relatively common complication of pregnancy, and it remains unclear whether the presence of COVID-19 virus in the placenta as described in this single report is related to development of the pregnancy complications. Pre-eclampsia can be detected early during routine antenatal visits and the most important message for women must be that they should continue to attend for their antenatal check-ups while being vigilant about social distancing, particularly in the third trimester of pregnancy.”
