Coronavirus may double severe complications in pregnancy

A Kaiser Permanente analysis of pregnant patients who tested positive for the coronavirus found more than double the risk of poor outcomes including preterm birth, venous thromboembolism (blood clot), and severe maternal morbidity, which includes conditions such as acute respiratory distress syndrome and sepsis. The study was published in JAMA Internal Medicine on March 21. An analysis of records for 43,886 pregnant individuals during the first year of the COVID-19 pandemic found that the 1,332 who had a coronavirus infection during pregnancy had more than double the risk of negative outcomes compared with individuals without the virus. “These findings add to the growing evidence that having COVID-19 during pregnancy raises risks of serious complications,” explained lead author Assiamira Ferrara, MD, PhD, a senior research scientist and associate director of the women’s and children health section in the Kaiser Permanente Division of Research.
