Meanwhile, U.S. health officials reported Wednesday that while the large majority of U.S. cases of swine flu continue to be mild, those who are hospitalized with more severe disease appear to be atypically young.
The median age of hospitalized individuals with swine flu is 15, which is younger than occurs with regular seasonal flu, Dr. Richard Besser, acting director of the U.S. Centers for Disease Control and Prevention, said during a Wednesday news conference.
"We are seeing the same distribution in hospitalized patients as we are in milder cases in the community, and that's younger than what you would see in seasonal flu," Besser said. "In seasonal flu, you tend to see a predominance of burden of disease in the elderly and in the very young, and here we are seeing it mo
