It was to explore the clinical characteristics of late pregnant women with asymptomatic infection of coronavirus disease 2019 (COVID-19) and the risk of intrauterine vertical transmission and breastfeeding transmission. The clinical data of a late pregnant woman with COVID-19 were retrospectively analyzed. The patient (singleton, cephalic) was admitted to the hospital on April 3, 2022. The patient had a dramatic increase in C-reactive protein after delivery, other blood routine tests were unremarkable, and the result of nucleic acid test was positive. On April 13, 2022, due to oligohydramnios, under measures such as positive pressure headgear and protective clothing in negative pressure operating room, second cesarean section combined with hysterorrhaphy (emergency) was performed to terminate the pregnancy, and the mother and baby were in good condition. Postpartum amniotic fluid, milk, and neonatal nucleic acid tests were negative. Corresponding treatment was given after cesarean section, and the patient was continuously monitored for nucleic acid detection to meet the discharge criteria of the COVID-19 and discharged and isolated. After discharge, the patient was followed up for 1 month. The newborn’s spirit, diet, and development were normal. The maternal cesarean section incision recovered well. Patient with COVID-19 in the third trimester has prolonged hospital stays and are difficult to treat. However, the virus was not found in amniotic fluid, breast milk, and newborn, for which COVID-19 does not lead to intrauterine vertical transmission and breastfeeding transmission in the third trimester.
