It does. But it beats catching a cold or flu every couple of months.
And it's not as if hand-washing is some kind of crazy placebo:
In a research published by British Medical Journal on November 2007, physical barriers, such as regular handwashing and wearing masks, gloves and gowns, may be more effective than drugs to prevent the spread of respiratory viruses such as influenza and SARS... Handwashing and wearing masks, gloves and gowns were effective individually in preventing the spread of respiratory viruses, and were even more effective when combined... Another study, published in the Cochrane Library journal on 2007, finds handwashing with just soap and water to be a simple and effective way to curb the spread of respiratory viruses, from everyday cold viruses to deadly pandemic strains.
I may just be lucky but I don't seem to get this, sure I catch some minor things but it is more like once a year. Your right if I was constantly catching things I would be more careful.
