The total number of confirmed cases varied from 27,717(Centers for Disease Control and Prevention (CDC) confirmed and probable cases) and 25,453 (total of all state confirmed cases) as of June 26, 2009.

Towards the middle of June 2009, the number of US cases surpassed those of Mexico, which had been the previous leader in diagnosed cases of the disease. Toward the end of June 2009, the number of deaths related to the virus in the US surpassed those of all other countries as well.

On June 25, the CDC released information revealing that there were more than likely over one million (1,000,000) cases of the disease in the US, most of which had not been reported or diagnosed.

December 10, 2009， CHICAGO (Reuters) - Swine flu has killed nearly 10,000 Americans, including 1,100 children and 7,500 younger adults, and infected one in six people in the United States since arriving last April, health officials said on Thursday.

“What we’ve seen for months is this is a flu that is much harder on younger people,” Dr. Thomas Frieden, director of the U.S. Centers for Disease Control and Prevention, told a media briefing.

He estimated that between April and November 14 there had been nearly 50 million cases of H1N1 influenza in the United States, mostly in younger adults and children. That was more than double the CDC’s estimate in November of 22 million Americans.

Frieden said more than 200,000 Americans had been hospitalized — about the same number who are affected by seasonal flu in an entire year.

“About 15 percent of the entire country has been infected with H1N1 influenza, or about one in six people,” Frieden told a media briefing.
