COVID-19 infection in late pregnancy associated with higher rates of preterm birth

SARS-COV-2 infection is associated with an increased risk of premature birth, but only for women who are infected in their final trimester, according to research published in the Open Access Journal of Plos One. The study of more than 5,000 pregnant women was one of the first to see the results of pregnancy for Covid-19 patients by Trimester.

There is limited data about pregnancy and COVID-19 infection. Until now, research has been small, generally limited to patients who are hospitalized, and often do not report results depending on infection during various stages of pregnancy. Noga Fallach and his colleagues from the Kahn-Sagol-Maccabi research and innovation center using anonymous data captured by Maccabi health services in Israel to match 2,753 infected women during pregnancy with 2,753 women without reported COVID-9 infections. Their study took place from 21 February 2020 to July 2, 2021. From infected women, 17.4% received Covid-19 during the first trimester, 34.2% for the second and 48.4% during the third trimester.

Covid-19 infections in the first and second trimester are not associated with an increased risk of premature birth. However, women infected in their third trimester are 2.76 times more likely to experience premature birth (2.76, 95% CI 1.63-4.67) – While women who are infected after 34 weeks of pregnancy are more than seven times more than seven times more than seven times more than seven times more than seven times more than seven times more than seven times more than seven times more than seven times more than seven times more than seven times more than seven times more than seven times more than seven times more than seven times more than seven times Maybe to experience premature birth (7.10, 95 % CI 2.44-20.61). There is a lower waters before delivery begins in infected women (39.1%) vs uninfected women (58.3%), and the proportion of the caesarean section and the loss of the baby is similar to both groups.

Because of an increased risk of premature birth in infected women during the end of pregnancy, researchers suggest that during their third trimester, and especially after 34 weeks of pregnancy, women must be advised for distance and wearing masks to reduce the risk of infection.
