Objective: To estimate fatality rates due to severe acute respiratory distress syndrome (ARDS) related to COVID-19 in Brazilian women, comparing pregnant and postpartum women with nonpregnant women.
Methods: A cross-sectional study of 12 566 pregnant and postpartum women (obstetric group) and 90 025 nonpregnant women (nonobstetric group) aged 15-49 years reported with severe ARDS in 2020. The Brazilian ARDS Surveillance System was used to compare the outcome (death or cure) between the groups, considering age, race, or comorbidities.
