5. Wash Your Hands
That sounds simple, but it’s incredible how many people forget it. The simple act of handwashing has been drilled into me since the first day of basic training as a critical component in infection control. Hand hygiene is essential to stop the spread of the infection and can dramatically reduce your chances of diarrhea, vomiting.
Many travelers carry small bottles of hand gel and these are great as a backup, but they are not a substitute for good old soap and water. Wherever possible, wash your hands under hot water for at least thirty seconds before and after eating and always after going to the bathroom.
