I've never met the "do not touch anything dirty after you washed your hands" and "close the faucet with a paper towel" (!) as a recommendation against spreading flu virus.

Especially if by "dirty thing" you mean the faucet handle.

I don't have a link but I do have a bit of (dated) experience that may be relevant.

Back a while ago I worked to pay for college. One of the several jobs I held was as CNA (Certified Nursing Assistant). Before they let you do the job there was a class you had to complete and one of the skills that you got tested on was washing your hands. Because, the first thing you did upon entering a room was to wash your hands and the last thing you did before leaving it was to wash your hands.

The process was as follows: set paper towel dispenser with 8-8 inches of paper towel so it is ready. turn on water to very hot. Wet hands and apply soap. Work soap into a lather for at least a minute and pay attention to make sure all surface areas of the hands and wrists are thoroughly scrubbed. Rinse under the hot water and tear off the paper towel. Use the paper towel to grab and dispense more paper towels for drying the hands. Once hands are dry, use the paper towels to turn off the faucet.

The keys to washing hands well seem to be related to water temperature and the length and vigorousness that is applied to the scrubbing. Once hands are in a 'clean' state the key to keeping them clean is to avoid contact with anything 'dirty'. I don't have a citation but if you really want something related to the measured effectiveness of hand washing techniques I am sure I could find some studies on pub med if you need them.

The faucet (and door) handle are the dirtiest areas in any bathroom, for two simple reasons: 1) most people that touch them have dirty hands - that's why they're here 2) they are not cleaned very often (watch the janitor)

Especially the door handle. I've seen enough people not wash their hands after using the urinal or even the toilet to ever want to touch that when leaving a public restroom.

Well, it's the recommended method from the Danish Serum Institute (SSI), which resembles the CDC in the United States.

Edit: That one is not specifically for flu, but too avoid infectious diarrhoea. We had a similar one at my job, specifically targeted against viral infections.

Depends on the ailment, Einstein. If its virus doesn't survive outside the body (which a lot of them do not), then "reducing the touching of things" does nothing.

And if the chances of catching it from a faucet are minuscule compared to someone having it breathing in the same room as you, then again, "reducing the touching of things" (especially when you already washed your hands) will gain you very little.

Ever heard of profiling and diminishing returns?

By all means, keep touching the faucet. Don't let me stop you.
