Pregnancy outcomes among pregnant women infected with COVID-19 with and without underlying disease: A case-control study.

ABSTRACT

Emerging infections have many effects on the health of pregnant mothers and their fetuses. Given the importance of coronavirus disease (COVID-19) during pregnancy, this study aims to evaluate the pregnancy and fetal outcomes in pregnant women with COVID-19 by using previous studies. To conduct this study, all studies related to the subject under discussion during the years 2000-2021 were checked out by systematic search in internationally available databases, including Web of Science, Science Direct, Scopus, PubMed, and Google Scholar. Finally, 21 closely related studies were selected to investigate the main objective. The results showed that common symptoms of COVID-19 in pregnant women included fever, cough, and muscle aches. The most common laboratory results included decreased blood lymphocytes and increased blood CRP. Consequences of pregnancy and childbirth in pregnant women included increased preterm delivery and increased cesarean section. Based on the results of the reviewed study, it can be concluded that newborns of mothers with COVID-19 were negative for COVID-19. However, the most common outcome for infants born to mothers with COVID-19 was low birth weight. Clinical signs, laboratory results, and radiographic criteria in pregnant women with COVID-19 are similar to those in non-infected adults. However, it is recommended that precautions be taken to prevent transmission of the virus, as well as preventive health instructions, particularly masking.
