Zika is an emergency; infected mosquitos may arrive in the U.S. this summer; “and there’s much that we still don’t know about it,” Tom Frieden, director of the Centers for Disease Control and Prevention, told Congress on Wednesday.
He said 30 or more states are at risk of transmission — southern states more so than others. And warmer weather accelerates the danger:
“Here, it’s possible that come summer, we will have a situation where a woman gets pregnant, and through bad luck, gets bitten by a mosquito that is infected with Zika and may have an affected child. We want to do everything in our power to prevent that from occurring.”
