In a worldwide study of 2,100 pregnant women, those who contracted COVID-19 during pregnancy were 20 times more likely to die than those who did not contract the virus, according to the University of Washington (UW).
UW Medicine and University of Oxford doctors led this first-of-its-kind study, published today in JAMA Pediatrics. The investigation involved more than 100 researchers and pregnant women from 43 maternity hospitals in 18 low-, middle- and high-income nations; 220 of the women received care in the United States, 40 at UW Medicine. The research was conducted between April and August of 2020.
The study is unique because each woman affected by COVID-19 was compared with two uninfected pregnant women who gave birth during the same span in the same hospital.
Aside from an increased risk of death, women and their newborns were also more likely to experience preterm birth, preeclampsia and admission to the ICU and/or intubation. Of the mothers who tested positive for the disease, 11.5% of their babies also tested positive, the study found.
