Bird Flu Isn’t Just China’s Problem Anymore

As the first human cases of H7N9 bird flu infection outside of China begin to emerge—in Taiwan and Hong Kong—health officials around the world are preparing for a potentially perfect storm for a massive flu outbreak. On Thursday, billions of Chinese will be on the move to celebrate the Lunar New Year, creating ripe conditions for the spread of the influenza virus from those already infected. And that means the next plane could bring a pandemic to the U.S. or anywhere else around the world. “The bottom line is the health security of the U.S. is only as strong as the health security of every country around the world,” says Dr. Thomas Frieden, director of the U.S. Centers for Disease Control.
