College campuses experienced a surge in flu cases last week just as vaccine shortages and delays were forcing many to postpone scheduled shot clinics, the American College Health Association reported on Wednesday.
Some of the increases in what the association called “influenza-like illnesses”â??widely thought to be the H1N1, popularly called swine fluâ??occurred in regions that had seemed to be recovering from severe outbreaks earlier this fall. The unexpected rebounds in the Southeast, Midwest, Mid-Atlantic, and Northeast have some health experts worried that the holiday season might bring some colleges a double dose of illness.
