Diarrhea is the most frequent health problem in travellers to developing countries. The syndrome is usually caused by an infection acquired by ingesting fecally contaminated food or beverages. Various bacteria, viruses and protozoa may cause traveller's diarrhea, the leading pathogen being enterotoxigenic E. coli. Antimicrobial drug prophylaxis is not recommended in view of the potential side effects. A more sensible approach is self-therapy with anti-motility agents in mild and uncomplicated cases, while for more severe illness an antimicrobial drug may be used. However, in view of the usually mild, self-limited disorder, therapy should be considered optional. Oral rehydration should be instituted when necessary.
腹泻是前往发展中国家旅行者中最常见的健康问题。该综合征通常由摄入受粪便污染的食物或饮料而获得的感染引起。各种细菌、病毒和原生动物都可能导致旅行者腹泻，主要病原体是产肠毒素大肠杆菌。鉴于潜在的副作用，不建议进行抗菌药物预防。一种更明智的方法是在轻度和无并发症的病例中使用抗动力药物进行自我治疗，而对于更严重的疾病，可以使用抗菌药物。然而，鉴于这种疾病通常症状较轻且具有自限性，治疗应被视为可选择的。必要时应进行口服补液。
