Prevention and self-treatment of travelers' diarrhea.

Abstract

Of the 50 million people who travel from the industrialized world to developing countries every year, between 20% and 50% will develop at least one episode of diarrhea, making it the most common ailment of travel. Although usually a mild illness, travelers' diarrhea can result in significant morbidity and hardship while overseas. Precautions can be taken to minimize the risk of developing diarrhea. If diarrhea does develop despite precautions, effective treatment, usually a combination of an antibiotic and an antimotility agent, can be taken along and started by the traveler at the onset of symptoms.
