Scientists reviewed the data of 400 thousand women aged 15 to 44 years with symptoms of coronavirus infection for the period from January 22 to October 3.
They found that pregnant women most often require intensive care - 10.5 people per 1000 pregnant women, compared to 3.9 per 1000 non-pregnant women.
The study also notes that women who are pregnant are more likely to die from the disease (1.5 per 1000 cases) than non-pregnant women (1.2 per 1000 cases).
In addition, pregnant women were three times more likely to require invasive ventilation for shortness of breath, as well as lung and heart support with hyperbaric oxygen. In general, all women over 35 were more likely to suffer from a severe form of the disease.
At the end of September, the CDC released another study. They studied pregnancy and childbirth in 4.4 thousand women with COVID-19 from March 29 to October 14. Of the four thousand children, 12.9% were born with preterm birth. In 2019, this rate was 10.2% of the entire US population as a whole.
Since the beginning of the coronavirus pandemic, 46 million cases of infection have been identified in the world, 1.2 million patients have become victims of the disease. The USA, India, Brazil and Russia were most affected by the disease.
