The National Institutes of Health has launched a multipronged study to understand the effects of the COVID-19 pandemic during and after pregnancy. Researchers will analyze the medical records of up to 21,000 women to evaluate whether changes to healthcare delivery that were implemented as a result of the pandemic have led to higher rates of pregnancy-related complications and cesarean delivery. They also seek to establish the risk of pregnant women with COVID-19 infection transmitting the virus to their fetus. Newborns will be monitored and assessed until they are discharged from the hospital. In addition, the study will track more than 1,500 pregnant women confirmed with COVID-19 infection, monitoring their health for six weeks after childbirth.
