zika

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.

Is your destination too dangerous? How do you protect yourself from health threats?

The first known human case of the virus was identified in a Florida teen after a year of tests. Known symptoms include fever and a severe rash, but it's unclear if it causes brain inflammation.

A study looks at the rate of miscarriage — and of babies born with the birth defect — among a group of pregnant women in Brazil. Researchers were surprised by what they found.

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.

Studies have shown that Zika can damage a fetus's brain in the third trimester. Would there also be an impact on the brain of a newborn?

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.

An outbreak in Brazil isn't slowing down as predicted. Dr. Anthony Fauci calls it "a potential threat" to the U.S.

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.

Scientists predicted that more than 1,000 babies would be born with the birth defect in Brazil last year. That never happened. Why?
