How a Zika virus outbreak has put an entire country at risk

Millions of people are infected with Zika, and that could put them at risk for birth defects and other serious health problems.

But it could also help bolster the Zika-control effort, as some of the Zika outbreaks have already shifted focus to the United States.

“It’s a big, big deal,” said John Smeaton, chief executive of Baphila, an organization that helps pregnant women infected with the Zika virus in Brazil.

“The more people who are able to get pregnant, the more people will be able to prevent Zika.”
