Adverse perinatal outcomes in pregnancies affected by severe COVID-19 infection.

Background: Severe COVID-19 infection in pregnancy has been associated with an increase in adverse perinatal outcomes, although studies differ regarding which outcomes are affected. Increased characterization of obstetrical and neonatal outcomes is needed, including details on indications for preterm delivery and additional neonatal adverse outcomes.

Objective: This study aimed to determine whether there is a higher rate of adverse perinatal outcomes with severe-to-critical COVID-19 infection compared with nonsevere COVID-19 diagnosed during pregnancy.
