The risk of stillbirth is almost twice as high as with pregnant woman To be available COVID-19 of those who don’t have the disease, according to a large U.S. health agency study published Friday. The Centers for Disease Prevention and Control (CDC) analyzed more than 1.2 million births from a hospital database between March 2020 and September 2021. The health department considers a stillbirth to be born from the 20th week of life.
Overall, stillbirths were rare (0.65% of births or about 8,150). But the risk of stillbirth was 1.90 times higher in women with Covid-19. In particular, 1.26% of births in women with Covid-19 were stillborn during this period, compared with 0.64% in the others.
Increased risk of variable delta
Delta-Variable This risk has also increased, noted the CDC, which analyzed periods before and after the spread of this variant in the country in July 2021. Compared to uninfected women, the risk for mothers with Covid-19 increased by 1.47 in the pre-delta period, 4.04 being the majority variable. “More studies are needed to investigate the role of maternal complications from Covid-19 on stillbirth risk,” the CDC wrote.
Some previous research has shown that the cause is inflammation and decreased blood flow to the placenta. They stressed that the CDC study is the most important so far to prove the link between stillbirth and the Covid-19 virus. They said they couldn’t tell if the women with Covid-19 were sick at the time of their hospitalization or if they had previously been infected. The vaccination status for women was also not available. The US health authorities strongly recommend getting vaccinated against Covid-19 before or during pregnancy.
