I'll watch out
. I tend to wash my hands with soap every time before eating (except if I have been at home). Sometimes I use sanitizer too and don't touch area of my mouth, eyes etc with unwashed hands.
Washing hands also the first thing when I arrive at home. I also use different clothes at home and 'outside' (especially now when I spend my days at a library and there visit dozen of people there everyday).
I think this helps me enough to stay healthy.
