Conclusion
No differences were found between Covid-19 infected and non-infected pregnant women according to delivery type, maternal and neonatal outcomes and also adverse pregnancy outcomes. Unfortunately, there is still no enough evidence about Covid-19 virus in pregnancy. Given the effect of many potential factors, such as the severity of maternal infection, the time interval between the onset of symptoms in mother and childbirth, the adequacy of the placental blood supply and many other factors on the effect of the virus on pregnancy outcomes, we suggest conducting more extensive prospective studies in this field. Future studies could lead to changes in current knowledge.
