ABSTRACT

The new variant B.1.1.529 of COVID-19 was reported to the WHO for the first time by South Africa on November 24， 2021. At present， Omicron has become the dominant strain in the world and is spreading rapidly. Although Omicron infected during pregnancy shows the lower risk of serious maternal and fetal complications than the previous variants and Delta variant， the rapid increase in the number of cases and the wide range of patients still worth attention of obstetricians. This article reviews the prevalence of Omicron variant infection， the clinical characteristics ， the prevention and the treatment of pregnant women infected with Omicron， as well as the breastfeeding of newborns. It is believed that Omicron infection will not increase the rate of early spontaneous abortion and the infant congenital malformations， but it may increase the risk of gestational hypertensive disorders， premature delivery， cesarean section， and postpartum hemorrhage in the third trimester of pregnancy.We put forward corresponding management strategies and suggestions to provide references for the diagnosis and treatment of novel coronavirus infection in pregnant women in China.
