(AP) -- The national count of swine flu cases has risen to 21,449 cases and the number of deaths have nearly doubled to 87.

The U.S. released the number of confirmed and probable cases Friday morning. The tally is up from the last week's count of 18,000 cases and 44 deaths.

Wisconsin, Illinois and Texas have had the most reported illnesses, and the Illinois count rose more than 500 since the last report. But CDC officials say much of the most recent flu activity has been in the Northeast. A quarter of the new deaths were in New York.
