New data shows pregnant women are at risk of serious illness and death if they have coronavirus infection, the CDC said Monday in a change from health advice from June.
Why is it important: Pregnant women with symptoms of COVID-19 are 70% more likely to need ventilation and a 70% higher risk of death than non-pregnant women with symptoms.
Big picture: The increased risk may be related to physiological changes during pregnancy, such as increased heart rate and oxygen consumption, decreased lung capacity, divert from cell-mediated immunity, the researchers said. the risk of thromboembolism.
- 409,462 symptomatic women aged 15 to 44 were studied, of which 23,434 were pregnant.
- Pregnant women are three times more likely to be hospitalized with ICU and require mechanical ventilation.
Remarkable: Although the sample is not nationally representative, another CDC study published on Monday found that women who test positive for COVID-19 have an increased risk of preterm birth.
- These findings are consistent with previous studies that showed slightly higher rates of preterm birth in women diagnosed with COVID-19.
