Insights
Critical COVID-19 in pregnancy is concerning. This case study found no severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) in a neonate or maternal samples, suggesting no vertical transmission in the third trimester.
Area of Science:
- Obstetrics and Gynecology
- Infectious Diseases
- Neonatology
Background:
- The COVID-19 pandemic has raised concerns about pregnant women and neonates.
- Limited data exists on the impact of SARS-COV-2 infection on pregnancy outcomes and neonatal health.
Observation:
- A case of a pregnant woman in her third trimester with critical COVID-19 is presented.
- Samples including amniotic fluid, umbilical cord blood, placenta, and neonatal gastric fluid were collected during cesarean delivery.
Findings:
- All tested specimens (amniotic fluid, cord blood, placenta, neonatal gastric fluid) were negative for SARS-COV-2 nucleic acid.
- No evidence of intrauterine vertical transmission of SARS-COV-2 was detected in this third-trimester pregnancy.
Implications:
- This case suggests a potential lack of vertical transmission in late-term pregnancies, but further research is crucial.
- Findings contribute to understanding the risks of COVID-19 in pregnancy and potential neonatal outcomes.
Abstract:
The coronavirus disease 2019 (COVID-19) has been a worldwide pandemic diseases, nearly 400,000 people died at now. The data of status of pregnant women and neonates after infection of severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) is limited. We report a case of pregnant woman in her third trimester with critical COVID-19, and amniotic fluid, umbilical cord blood, placenta, and neonatal gastric fluid were retained during cesarean section. The SARS-COV-2 nucleic acid test results of these specimens were negative. There is no evidence of intrauterine vertical transmission during delivery in the third trimester, but the data are limited and need to be further explored.
