Introduction and objective: From the date of diagnosis of the first case of SARS-CoV-2 infection in November 2019. at the time of writing this article, more than 530 million COVID-19 cases have been confirmed worldwide. In Poland, the number of confirmed infections is over 6 million and there are 116,632 deaths. Unfortunately, there is no data on how many of these cases concern pregnant women. Based on the available articles, in this paper we will provide an overview of the current state of knowledge about the course of COIVD-19 during pregnancy. Analysis of the current state of knowledge on the course of COVID-19 in a group of pregnant patients and the impact of COVID-19 on pregnancy outcomes. What's already known about this topic?: The course of COVID-19 in pregnant patients is associated with more frequent hospitalization in intensive care units, while the symptoms do not differ statistically from those reported in the population of women of reproductive age. Regarding the effects of COVID-19 on pregnancy outcomes, many published studies show that infection during pregnancy is associated with a number of adverse effects, including pre-eclampsia, preterm labor and stillbirth, especially among pregnant women with severe COVID-19 disease. Abstract: Adaptive changes in pregnancy have the potential to influence the susceptibility and severity of COVID-19. The analyzed studies showed similar symptoms of COVID-19 compared to women of reproductive age. Most of the cases were associated with a mild course of the disease. However, an increased risk of hospitalization in intensive care units, oxygen therapy, and mechanical ventilation in pregnant patients was found. The risk of premature delivery, fetal death, pre-eclampsia, and surgical termination of pregnancy is statistically higher in the group of pregnant COVID-19 patients.
