Study: 6% of U.S. pregnancies with Zika virus linked to birth defects
About 6% of U.S. completed pregnancies with laboratory evidence of possible recent Zika infection had a fetus or infant with evidence of a Zika-related birth defect, according to a study published online yesterday by the Journal of the American Medical Association. Of 442 completed pregnancies included in the study, 26 fetuses or infants had birth defects, including 18 (4%) with microcephaly. According to a separate study reported yesterday by the Centers for Disease Control and Prevention, Zika virus can continue to replicate in infants’ brains even after birth.

A new toolkit from the American College of Obstetricians and Gynecologists also offers Zika resources for clinicians.
