THE EFFECTS OF COVID-19 ON PREGNANCY: A REVIEW STUDY

In December 2019, the COVID-19 was first reported in Wuhan, China, and the
World Health Organization declared its outbreak an international concern. Pregnant women are among
the high-risk groups that COVID-19 can have a significant impact on their health. Since COVID-19 can
increase maternal and fetal mortality, this narrative review study was performed to evaluate the
complications of COVID-19 in pregnant women.
Materials & Methods: This study reviews data from several reliable databases such as PubMed, SID,
Magiran, Web of Science, and Scopus, without time limit until October 2020. The keywords included
"Pregnancy", "Pregnant women", and "COVID-19". According to the inclusion criteria, finally, 26
articles were included in the study.
Results: In this study, most reported maternal and fetal complications in pregnant women with COVID19

include thrombotic events, acute respiratory distress syndrome, fetal distress, preterm delivery,
postpartum fever, PROM, vaginal bleeding, and preeclampsia. The most common effect of COVID-19
during pregnancy is on the coagulation, immune and cardiopulmonary systems, which is mostly due to
the stimulation of the immune system. It can also affect the coagulation system and cause thrombotic
events.
Conclusion: It seems that COVID-19 can increase the severity of the disease and its complications in
pregnant women and threaten the health of the mother and fetus
