"There is virtually no evidence that people can catch the influenza virus from germs that they pick up on their hands, according to Arthur Reingold, head of epidemiology at the University of California, Berkeley, and codirector of the CDC-funded California Emerging Infections Program. Instead, humans are most likely to catch influenza by breathing in microscopic particles exhaled by infected people.
Reingold and other epidemiologists don't discount hand-washing as an important tool in public health: there is plenty of evidence that it prevents other nasty bugs, including the common cold, many respiratory infections, and viruses that cause diarrhea. But Reingold is bothered by the lack of science supporting the CDC's message, and he worries that the emphasis on a simple measure like hand-washing creates a false sense of security from H1N1 and tamps down the discussion of more difficult preventive measures."
WOW. I did not know that.
