Zika causes birth defects in one in 10 pregnancies: U.S. studyBy Julie Steenhuysen CHICAGO (Reuters) – About one in 10 pregnant women with confirmed Zika infections had a fetus or baby with birth defects, offering the clearest picture yet of the risk of Zika infection during pregnancy, U.S. researchers said on Tuesday. The report from the Centers for Disease Control and Prevention is the first to analyze a group of U.S. women with clear, confirmed test results of Zika infection during pregnancy. Once considered a mild disease, a large outbreak of the virus that began in Brazil in 2015 and quickly spread through the Americas revealed that the mosquito-borne virus can cause severe brain damage and microcephaly, or small head size, when women are exposed during pregnancy.
