(AP) -- The largest U.S. analysis of adult hospitalized swine flu patients has found that 46 percent did not have asthma or any other underlying condition.
Health officials looked at 1,400 adult swine flu hospitalizations in 10 states. A Centers for Disease Control and Prevention official released some of the details at a Tuesday press conference.
The CDC has said most swine flu-infected people who have grown severely ill had underlying conditions, but the new details suggest it may not be a large majority.
CDC officials added that it's preliminary data, and obesity was not classified as an underlying condition.
