Study cohort demographics
There were no differences in maternal age, BMI, gestational age at delivery, and birth weight between women with the COVID-19 group with healthy controls. (Table 1). Of 19 women with COVID-19, 13 women had the asymptomatic or mild disease (AMD) (68.4%), and 6 of those had moderate or severe disease (31.6%). The rate of preterm birth (PTB) was 15.3% (n=3) in the COVID-19 group; 2 of 6 women (33.3%) with moderate or severe disease and 1 of 13 women (7.7%) with asymptomatic or mild disease (Table 2).
In asymptomatic or mild disease, 61.5% of those had infection in the second trimester and 38.5% in the third trimester (Table 2). Two women with moderate or severe disease received both antibiotic and antiviral medications. Seven patients received low molecular weight heparin during the active period of COVID-19 disease (Table 2).
