Traveler's diarrhea.

Abstract

Traveler's diarrhea (TD) is one of the most common illnesses afflicting the modern traveler. TD refers to a watery diarrhea that varies in severity from tolerable to incapacitating and that develops in individuals during or within 10 days of returning from travel to developing or low-/middle-income countries. Most cases of TD are self-limiting, but in consideration of the ease of international travel, it is important for providers to diagnose and manage TD with the best available evidence.
