Does Asia Have a Secret Weapon Against Zika?

"When you go outside in Malaysia, you get bitten everywhere. It's not like in the U.S. Mosquitoes are everywhere!" says Jamal Sam, a virologist at the University of Malaya in Kuala Lumpur.

But there's something hiding in Southeast Asia that may protect the continent from Zika. It's in their backyards, their flower pots and birdbaths. And this secret weapon is the exact opposite of what you might expect.

"There's lots of evidence that Zika is already present in Southeast Asia," Sam says.

That's right: Zika could protect Asia from Zika.
