For decades, Zika had been relatively innocuous. In 2015, that changed. A new study unravels the mystery of what caused thousands of cases of microcephaly.
Scientists plan to release millions of sterile, male bacteria-infected mosquitoes in California, to breed with wild females. They're hoping for a "steep decline" in the species that carries Zika.
They've been largely responsible for warding off mosquitoes at home — and caring for the children born with microcephaly. A new study says that the government has not given them the support they need.
The Zika outbreak in Florida is officially over. And cases are dropping across the Caribbean. But doctors say the risk to pregnant women there — whether residents or travelers — isn't gone.
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.
