工业化国家的人群去发展中国家旅游时所发生的由不同病原引起的一种特殊短暂性水泻,称之为旅游者腹泻。本病发病率颇高,严重威胁旅游者健康,已成为感染性腹泻中值得进一步研究的课题。流行病学北美、北欧的人群去拉丁美洲、非洲、南欧、亚洲、中东等地区旅游时,易发生本症,侵袭率自30～80％不等。非热带工业化地区到热带以及亚热带发展中国家或地区的旅游者较易发病,乃因这些地区的卫生条件较差,饮水和食品卫生标准执行和管理不严所致。自其他国家或地区去美国旅游者中也可有腹泻发生,但侵袭率极低,Ryder 报告147名学者赴美集会,仅3人发生腹泻(2％)。
A special transient diarrhea caused by different pathogenic bacteria that occurs in people in industrialized countries while traveling to developing countries is called traveler diarrhea. The high incidence of this disease, a serious threat to the health of tourists has become a subject worthy of further study in infectious diarrhea. Epidemiology Northern and Northern European populations to travel to Latin America, Africa, southern Europe, Asia, the Middle East and other regions, prone to the disease, the invasion rate ranging from 30 to 80%. Tourists in non-tropical industrialized areas to tropical and sub-tropical developing countries are more vulnerable due to poor sanitation in these areas and poor enforcement and management of drinking water and food hygiene standards. Diarrhea can also occur from other countries or regions to U.S. tourists, but the rate of invasion is extremely low. Ryder reported that 147 scholars went to the United States for assembly and only three reported diarrhea (2%).
