ANN ARBOR, Mich.---Masks and hand hygiene could cut the spread of flu-like symptoms up to 75 percent, a University of Michigan study found.
A new report shows the second-year results (2007-2008) of the ground-breaking U-M M-Flu study found up to a 75 percent reduction in flu-like illness over the study period when using hand hygiene and wearing surgical masks in residence halls, said Allison Aiello, associate professor of epidemiology in the U-M School of Public Health. Aiello and Dr. Arnold Monto, SPH professor of epidemiology, are co-principal investigators of the M-Flu study.
