When travelling I try not to touch things, like escalator rails, anything on a public bus/metro etc. the button on an elevator, I use my knuckle rather than finger. I do wash my hands more often when I travel. Even on the airplane I generally take a wet towel and wipe the seat belt buckel, arm rest and audio buttons and if a seat back screen I usually wipe that down also. I am not a fanatic but i do like to keep as clean as possible, anyone have the same views on this?
