Résumé
TRAVELLER'S DIARRHEA. Despite the global economic development and improvement of infrastructures in the context of mass tourism, diarrhea remains one of the most common health problems encountered by travelers. Majority of these diarrheas are selflimiting but can lead to seeking primary medical care. Two clinical entities can be distinguished: acute diarrhea and persistent diarrhea, resulting in most cases respectively from an infectious bacterial and parasitic origin. The clinician must keep in mind the signs that can lead to immediate or delayed complications and be aware of emergency situations. This article presents the main etiologies and their management, along with the health education messages to deliver in order to prevent risky situations.
