This confirms what researchers have suspected with mounting evidence about harms caused by the virus.
Federal health officials confirmed Wednesday that the Zika virus causes a rare birth defect and other severe fetal abnormalities, marking a turning point in an epidemic that has spread to nearly 40 countries and territories in the Americas and elsewhere.
Scientists at the Centers for Disease Control and Prevention conducted a careful review of existing research and agreed that the evidence was conclusive, Director Thomas Frieden said. It is the first time a mosquito-borne virus has been linked to congenital brain defects.
