Maternal-fetal transmission in the second or third trimester of pregnancy of the SARS-COV-2 virus could explain some late fetal losses. Finding a cause in the context of fetal loss is essential for parents and caregivers. It helps to understand the history of the disease, to address the possible risk of a recurrence and to plan for future pregnancies. If the maternal-fetal transmission of COVID 19 is confirmed and that it is responsible for obstetric complications, a preventive action could be proposed to the patients by the preconception vaccination. The investigators are seeking to clarify the frequency of this transmission is information awaited by caregivers, women, couples in particular when the latter are in distress from late fetal loss.
