Mar 04, 2016 Scientists today moved two steps closer to proving a link between birth defects and Zika virus, with a clinic-based team documenting outcomes in ill Brazilian pregnant women, many of whom delivered babies with health problems, and a lab-based group showing how the virus likely kills or disrupts developing fetal brain cells. In the first study, researchers followed 88 pregnant women who sought care for a rashlike illness at the Oswaldo Cruz clinic in Rio between September 2015 and January 2016. Of the total, 72 tested positive for Zika virus on the basis of blood tests, urine tests, or both. The timing of their infections ranged from 5 weeks to 38 weeks gestation. The women were of all socioeconomic levels and lived in a wide range of neighborhoods across the city. More than half reported similar illnesses in family members, and more than half reported their acute infection during the second pregnancy trimester. Fetal ultrasounds were done in 42 of the women who tested positive for Zika virus and in all 16 whose test results were negative. Abnormalities were detected in 12 (29%) of the women who tested positive for the virus but in none of those who tested negative. Medclinician |
