Clinical Profile, Disease Severity and Perinatal Outcomes of Laboratory-confirmed COVID-19 among Pregnant Women Delivering in a Tertiary Care Centre.

Background: Pregnant women and their fetuses represent a high-risk population during coronavirus disease 2019 (COVID-19) pandemic. During pregnancy, body undergoes significant physiologic, mechanical, and immunologic alterations which increases susceptibility to infections. Thus pregnant women are at an increased risk for severe illness from COVID-19. This study explored the clinical profile, disease severity, and perinatal outcomes of pregnant women with COVID-19.

Methods: A retro-prospective cross-sectional study was conducted at KIST Medical College after ethical approval. All women (1227) who delivered from 15 April 2020 to 15 October 2021 and underwent the COVID-19 screening by Reverse Transcriptase Polymerase Chain Reaction were studied. COVID-19 positive women (44) were further analyzed and classified as asymptomatic, mild, moderate, severe, and critical diseases. Data was collected in proforma by reviewing patients' records. The data analysis were done in SPSS version 26. A descriptive statistical test and chi-square test were done.

Results: The prevalence of COVID-19 among delivering pregnant women was 3.6% (44/1227). Majority were asymptomatic 79.5% (35). About 16% (7) had mild illness and 4.5% (2) had moderate illness. The caesarean rate was 34.1% (15/44) among COVID-19 positive women. Stillbirth and preterm birth was observed in 2.3% (1) and 4.5% (2) respectively. The COVID-19 infection rate in a neonate was 4.5%.

Conclusions: The severity of COVID-19 among delivering pregnant women was less. The perinatal outcome was also favourable. The overall prognosis of COVID-19 among mothers and newborns was good. Further research is needed to understand the true magnitude of risks and management, more so with the emergence of new variants.
