Vacation diarrhea. How should it be managed?

Traveler's diarrhea in North America is most often a self-limited disease that requires little medical intervention unless the course is prolonged or especially severe. Diagnosis is almost always made by a stool examination or culture. The most common causative organisms are Campylobacter jejuni and Giardia lamblia. Enterotoxigenic Escherichia coli is a less frequent cause. Patients should be advised regarding the need for fluid replacement. Antibiotic therapy should be considered only in rare circumstances.
