[Management of traveler's diarrhea].

Traveler's diarrhea is very common, cosmopolitan, and usually benign. However, it can lead to significant complications because of underlying conditions (very young or elderly travelers, immunodeficiency...) or professionnal reasons (politicians, artists...). Prevention is based primarily on hygiene standard, chemoprophylaxis should be reserved for special situations. Although traveler's diarrhea is most often of bacterial origin, rehydration is the mainstay of its management.
