Zika birth defects

NPR's Robert Siegel talks to Margaret Honein, co-leader for the CDC Zika Response Team's Pregnancy and Birth Defects Task Force, about the latest guidance on Zika at the start of mosquito season.

The Zika virus continues to impact a small number of pregnant women and their babies in the U.S., and there is no sign of it slowing down. "Zika is here to stay," the CDC's acting director says.

Women who were infected with Zika virus while abroad and then came to the U.S. had complications about 6 percent of the time, a study finds. First-trimester exposure was linked to more birth defects.
