Preterm birth among pregnant persons with severe acute respiratory syndrome Coronavirus 2 infection.

ABSTRACT:

Objective

We examined the relationship between trimester of SARS-CoV-2 infection, illness severity, and risk for preterm birth.

Study design

We analyzed data for 6336 pregnant persons with SARS-CoV-2 infection in 2020 in the United States. Risk ratios for preterm birth were calculated for illness severity, trimester of infection, and illness severity stratified by trimester of infection adjusted for age, selected underlying medical conditions, and pregnancy complications.

Result

Pregnant persons with critical COVID-19 or asymptomatic infection, compared to mild COVID-19, in the second or third trimester were at increased risk of preterm birth. Pregnant persons with moderate-to-severe COVID-19 did not show increased risk of preterm birth in any trimester.
