Key clinical point: Pregnant women with SARS-CoV-2 infections were more likely to have poor pregnancy outcomes and more severe disease.
Major finding: Rates of preterm birth were higher among women with confirmed SARS-CoV-2 infections compared with the national average (12.9% vs. 10.2%). Pregnant women with COVID-19 disease were significantly more likely than nonpregnant women to be admitted to intensive care (10.5 per 1,000 cases vs. 3.9 per 1,000 cases).
Study details: The data come from 4,442 pregnant women with COVID-19 and known pregnancy outcomes identified through the Surveillance for Emerging Threats to Mothers and Babies Network (SET-NET), and a second study of 23,434 pregnant women and 386,018 nonpregnant women aged 15-44 years with laboratory-confirmed COVID-19 infections identified through the National Notifiable Diseases Surveillance System (NNDSS).
