ATLANTA (WKOW) -- 46 percent of adult H1N1 patients that we hospitalized in the U.S. did not have asthma or any underlying conditions.
That's according to an analysis by the Centers for Disease Control and Prevention.
Officials looked at 1,400 adult patients in 10 states.
Previously the CDC had said most of those infected with H1N1 and grew severely ill had underlying conditions, but these new numbers could suggest it may not be a large majority.
CDC officials added that it's preliminary data.
