Fetal growth and hemodynamics during SARS-CoV-2 infection: a short literature review

Abstract

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a virus that, having crossed species, has caused human disease from 2019 - COrona Virus Disease 2019 (COVID-19). Pregnant women are potentially at high risk of contracting SARS-CoV-2 infection when compared to non-pregnant matched controls. Pregnancy is also complicated with a higher risk of developing severe SARS-CoV-2, including respiratory diseases, admission to the intensive care unit and mortality, even after adjusting for confounding risk factors. Moreover, data on the effect on fetal outcome including preterm delivery and perinatal morbidity are still conflicting, the risk of vertical transmission (i.e., transmission of SARS-CoV-2 from the mother to the fetus or the newborn) is considered low but there is evidence that a significant proportion of placentas where SARS-CoV-2 occurred during pregnancy show histopathological findings suggesting placental hypoperfusion and inflammation. In this review we will present the available data on the effects of SARS-CoV-2 infection on fetal growth and maternal hemodynamics
