The largest study to follow women infected with Zika while they were pregnant finds about 6 percent of children had problems at birth, but 14 percent had complications by their first birthday.

Cities and towns are preparing for mosquito season and the threat of the Zika virus by spreading pesticides. It worked for the West Nile virus but may not be as effective for controlling Zika.
