COVID-19 has turned into a global pandemic since it was first detected in 2019, causing serious public health problems. Our objective was to investigate the impact of COVID-19 on pregnant women and newborns, who belong to the vulnerable segments of society. Our study involved the histopathological examination of placentas and umbilical cords from two groups of pregnant women. Group I consisted of pregnant women who had never tested positive for COVID-19 during their pregnancy (n: 20). Group II consisted of pregnant women who had contracted COVID-19, exhibited moderate and mild symptoms, and recovered from the disease before giving birth (n: 23). Furthermore, we employed immunofluorescence techniques to detect macrophage activity in the umbilical cord. Prenatal assessments were based on maternal complete blood counts and coagulation assays (n:40 in both groups). Newborn conditions were evaluated using birth weight, height, head circumference, and APGAR (n:40 in both groups). Our analyses reveal that COVID-19 causes placental and umbilical cord inflammation and maternal and foetal vascular malperfussion. Our immunofluorescence investigations demonstrate a notable increase in macrophage numbers and the macrophage-to-total cell ratio within the COVID-19 group. In this aspect, this study provides the initial report incorporating macrophage activity results from Warton’s jelly in pregnants who have recovered from COVID-19. We have also ascertained that COVID-19 abbreviates gestation periods and concurrently diminishes maternal haemoglobin concentrations. Consequently, COVID-19 with mild and moderate symptoms during pregnancy, causes significant changes to the placenta and umbilical cord, but propitiously does not cause a significant difference in the neonatal outcomes.
