Swine Flu

The Center for Disease Control and Prevention released estimates today that there have been 22 million H1N1 cases in the U.S. between April and October.

The estimates show that between 14 million and 34 million cases of H1N1 occurred between April and October 17, and the mid-level in this range is about 22 million people.

The CDC released numbers on Nov. 11 that approximately 4,000 Americans likely have died from swine flu, which was four times more than conservative estimate they'd been using up until now. CDC numbers also show that about 36,000 Americans die of seasonal flu each year.
