In this study, a total of 164 pregnant individuals were studied, consisting of 24 uninfected healthy patients as a control group and 140 individuals who contracted COVID-19. Both groups delivered at about the same time, 37 to 38 weeks. Preterm birth occurred at almost 3 times the rate with the patients with COVID-19 when compared with those without. About 75% of the patients with COVID-19 were either asymptomatic or had mild symptoms, according to the study.
