Analysis of Pregnant Women Recovered From Antenatal SARS-CoV-2 Infection: An Observational Study

Background and objective The global health care system is facing the challenge of diagnosing and treating the ongoing coronavirus disease 2019 (COVID-19) pandemic. Pregnant women belong to a vulnerable group, and the effect of the virus on the mother and fetus is not well established. The aim of the study was to understand the maternal and fetal outcomes after recovery from antenatal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Methods This was a retrospective observational study conducted at Tata Main Hospital, Jamshedpur, India. It included all COVID-19-negative pregnant women who had delivered between 1(st) January 2021 and 31(st )August 2021 and had tested positive in the antenatal period (by reverse transcription-polymerase chain reaction (RT-PCR)), the details of which are available in the hospital database. Results A total of 53 women were included in our study who had tested positive in the antenatal period and had turned negative during delivery. Out of the 53 women, 5.7% were infected in the first trimester, 34% in the second trimester, and 60.3% were positive in the third trimester. We found an asymptomatic subgroup in 52.8% of women and mild symptoms in 41.5% of women. Two women were admitted in their antenatal period with moderate COVID-19 disease and one with severe. Preterm births between 34 weeks and 37 weeks were seen in 26.4% of women. Vaginal delivery accounted for 30.2% of cases. The most common indications for cesarean section were fetal distress (17%), previous cesarean section (17%), and unwillingness for vaginal delivery. Out of the 53 pregnant women included in the study, acute respiratory distress syndrome (ARDS) was seen in two women- one diagnosed intraoperatively during cesarean section and the other was diagnosed on the first postoperative day. Conclusion The study showed that pregnant women infected with SARS-CoV-2 usually have no/mild symptoms, and they recover well and have favorable maternal and neonatal outcomes. However, perinatal vigilance is advisable in these cases, as there is a risk of developing respiratory morbidity.
