Travelers' diarrhea is of concern to practitioners in temperate countries in two ways: people ask advice for effective prophylaxis before they leave for tropical regions, and returning travelers often complain of diarrhea after a journey to the tropics. Diarrhea at the beginning of a trip to southern regions is mainly due to bacterial pathogens; later, a parasitic origin for diarrhea becomes an increasing possibility. A rational and economic diagnostic approach to the diarrhea of returning travelers does not necessarily and always include bacteriological stool cultures. Situations warranting a wait-and-see symptomatic treatment are discussed. The authors believe that chemoprophylaxis for traveler's diarrhea should not be prescribed as a general measure.
人们在前往热带地区之前会寻求有效预防措施的建议，而返程的旅行者经常在去过热带地区旅行后抱怨腹泻。前往南部地区旅行初期的腹泻主要由细菌病原体引起；之后，腹泻由寄生虫引起的可能性越来越大。对于返程旅行者腹泻的合理且经济的诊断方法不一定也不总是包括粪便细菌培养。文中讨论了值得采取观望对症治疗的情况。作者认为，不应将旅行者腹泻的化学预防作为常规措施来开处方。
