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).
