Background: Data about obstetric complications of maternal infection by SARS-CoV-2 remain sparse.
Case: A 40-year-old pregnant woman, gravida 3 para 1 with no previous obstetric complications, presented a late miscarriage at 16 weeks of gestation on day 9 of COVID-19 disease. The results of her nasopharyngeal swab for SARS-CoV-2, tested the same day, were negative, but the placenta was infected by SARS-CoV-2 and serology was positive 11 days later. No other obstetric or infectious cause was found to explain this outcome.
Conclusion: This case strongly suggests that SARS-CoV-2 may lead to a late miscarriage.
