Flu on campus: What works, what doesn't
By Julie Steenhuysen
CHICAGO (Reuters) - Cramped living quarters on college campuses increase students' chances of being infected with all kinds of flu, but scrupulous hand hygiene and simple face masks may help some stay healthy, at least until swine flu vaccines become available next month, health experts say.
Last week, U.S. colleges and universities reported a 21 percent increase in new cases of influenza-like illness, or 6,432 cases, at 253 schools tracked by the American College Health Association.
So far this academic year, there have been 13,434 reported cases of flu-like illness, most of which are presumed to be swine flu because seasonal flu has not gotten under way. Many schools have just begun classes.
At the University of Michigan, researchers are tallying results from a two-year study on how best to protect students from flu-like illness.
In the first year of the study, the team found wearing face masks and using alcohol-based hand sanitizer helped cut the risk of flu by as much as 50 percent.
"There was a significant reduction in influenza-like illness," Allison Aiello, an assistant professor of epidemiology, said in a telephone interview.
Aiello said in the first year of their study, the flu season was light, but results of the second year, expected to be published in the next few months, would give a better picture of how masks and hand sanitizer worked against lab-confirmed cases of flu.
"With college students, the concern is that students are living in the residence halls, which can be quite crowded," Aiello said. Continued...
