Years after agreeing to take part in research, families of children with congenital Zika syndrome are feeling abandoned.

In 2015, the mosquito-borne virus Zika exploded in South America. Health experts predicted it would erupt in Africa. But a major outbreak never happened. Now scientists think they understand why.

Given the choice between an animal and a human, the Aedes aegypti species prefers ... us. A new study explains how that happened.

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.
