A Study to Evaluate COVID19 Pregnancy Risks


About this study

It is unclear if and how COVID19 can be passed from mother to child. Therefore, we aim to collect maternal and fetal samples from COVID19-infected pregnant women and compare them to pregnant women who have clinical indications for COVID 19 testing at the time of hospital admission but end up being COVID19- (control group). Pregnant women who are either COVID19+ or COVID19- with symptoms will be followed during this study. Our objective is to understand the prevalence of maternal fetal transmission, risk factors and outcomes of a COVID19+ pregnancy, and how the virus can be passed from mother to baby in the population of Mayo Clinic patients.
