We found a low prevalence of SARS-CoV-2 (2.7% [5/188]) among pregnant and postpartum patients after initiating universal testing. Prevalence among symptomatic patients (22.2% [4/18]) was similar to initial targeted screening approaches (19.1% [8/42]). Among 170 asymptomatic patients, two were positive or inconclusive, respectively; repeat testing at 24 hours was negative.
