Travelers' diarrhea is the most frequent health problem during a stay in developing countries. A recent study basing on interviews with 16,568 charter flight passengers returning to Europe from 13 destinations in various climatic regions provides epidemiological data on a worldwide scale. Significant differences in diarrheal incidence varied not only between individual destinations, but also between hotels in the same area. The highest incidence for a two weeks' stay exceeded 50% in some regions of North and West Africa. Persons under 30 were more often affected than older travelers. Within international groups meeting in developing countries, the risk varied according to the patient's country of origin, with the residents of industrialized nations being most often affected. Even in the tropics, diarrhea usually takes a short and mild course. The various regions show unessential differences in chronology and symptomatology. E. coli is the most frequent causative agent of this ailment.
旅行者腹泻是在发展中国家停留期间最常见的健康问题。最近一项基于对16568名从不同气候区域的13个目的地返回欧洲的包机乘客进行访谈的研究，提供了全球范围内的流行病学数据。腹泻发病率的显著差异不仅存在于各个目的地之间，也存在于同一地区的不同酒店之间。在北非和西非的一些地区，两周停留期内的最高发病率超过了50%。30岁以下的人比年长的旅行者更容易受到影响。在发展中国家举行会议的国际团体中，风险因患者的原籍国而异，工业化国家的居民受影响最为频繁。即使在热带地区，腹泻通常病程较短且症状较轻。不同地区在发病时间和症状学方面显示出不重要的差异。大肠杆菌是这种疾病最常见的病原体。
