Maternal and Neonatal Complications, Outcomes and Possibility of Vertical Transmission in Iranian Women with COVID-19

The emergence and fast spread of coronavirus disease 2019 (COVID-19) threatens the world as a new public health crisis. Little is known about its effects during pregnancy. This study aimed to investigate the clinical manifestations of COVID-19 on maternal and neonatal outcomes.

In this systematic review, PubMed, Scopus, Web of Science, and Google Scholar databases were searched focusing on pregnancy and perinatal outcomes of COVID-19.

The initial search yielded 1236 articles, from which finally 21 unique studies, involving 151 pregnant women and 17 neonates, met the criteria. Mean ± SD age of included mothers and mean ± SD gestational age at admission were 30.6 ± 6.2 years and 30.8 ± 8.9 weeks, respectively. The common symptoms were fever, cough, fatigue, dyspnea and myalgia. The mortality rates of pregnant women and neonates were 28 out of 151 (18.5%) and 4 out of 17 (23.5%), respectively. Most of the neonates were preterm at the time of delivery. Three neonates had positive RT-PCR test on the first day after birth and three others on day two. On the average, neonate’s PCR became positive on day 4 for the first time.

Early diagnosis of COVID-19 is crucial due to the possibility of the prenatal complications. Strict prevention strategies may reduce the risk of mother to infant transmission.
