Handwashing certainly would reduce PASSING a disease, but it won't necessarily always help you from GETTING a disease.

For instance, if I use the restroom at the rail yard in Seattle, it is on the second floor. Even if I wash my hands at the sink, dry with the always-available paper towels and open the door with the same towels, I have to use a banister to go back down the stairs. I've seen people cough into their hand and then put their hand back on the banister.

I try to use the alcohol stuff once I get into the car. But multiply this issue through your life: doors, door handles, shopping carts and baskets, countertops, pens in banks, etc.

(And don't even bother suggesting not using the banister. I grew up in flat buildings and am very klutzy. I can fall going down the stairs, up the stairs, or simply standing on the stairs.)
