travelers’ diarrhea is often used as a generic term for any illnesses ranging from an upset tummy to loose stools during or after travel. it could mean just excess gas or a variety of symptoms that can occur from a change in the types of food or beverages we are used to – or most commonly to contamination of food or beverages. and it's not just food and beverages. touching your mouth or nose with contaminated hands may be all it takes.
