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.
About 5 percent of pregnant women infected with Zika in Puerto Rico and other U.S. territories last year had babies with birth defects, says the federal health agency. And the risk isn't over.
Scientists predicted that more than 1,000 babies would be born with the birth defect in Brazil last year. That never happened. Why?
Cytomegalovirus is everywhere, and it usually doesn't make people sick. But if a woman gets infected while pregnant, in rare cases it can cause serious problems for the baby.
But it's too early to say whether the epidemic isn't has bad as the agency first predicted back in February.
But they'll have to wait a while. The portion of the $394 million Congress allocated to help pregnant women find out more quickly if they have Zika isn't expected to get to strained labs until 2017.
A new study from Brazil provides an early snapshot of what the future could hold for children infected with Zika, then born with the brain defect.
