Swine flu surges on U.S. campuses

Influenza-like illnesses on college campuses, generally presumed to be H1N1 flu, jumped 34 percent in the week ending Friday, according to data compiled by the American College Health Association.

A total of 8,861 new cases and 20 hospitalizations were reported by the 270 colleges and universities that provide data.

Unexpectedly, a resurgence of flu activity was observed in several regions that previously had seen declines, including the Southeast, Midwest, Mid-Atlantic and Northeast.
