Good Personal Hygiene
If your hands have been contaminated by touching something loaded with bacteria or viral particles (feces, urine, saliva) and you do not wash your hands,
- you can accidently introduce the bacteria or viral particles into your own mouth when you do things such as:
- touch food as you put it into your mouth,
- rub the corner of your mouth,
- smoke your cigarette, or
- even put on chapstick !
