简介：在刚果民主共和国的半城市环境中，本研究旨在了解伤寒（TF）爆发的动态，并评估：a）TF传播热点的存在和B）在这些热点中确定的伤寒病例与普通人群之间在社会人口特征、卫生习惯和饮用水来源方面的差异。研究方法：这是一项使用水源微生物分析和结构化访谈问卷对2011年刚果民主共和国基奎特TF疫情进行的回顾性分析。结果：共报告1430例TF病例。疫情的流行曲线显示，位于基奎特的三个军营（Ebeya 3.2%; Ngubu 3.0%;和Nsinga 2.2%）的最早和最高峰值发病率（AR），而其他受影响地区的平均峰值AR为0.6%。共访问了来自军营和高负担卫生区的320例病例。伤寒病例与多个家庭共用一个厕所（P
Introduction: in a semi-urban setting in the Democratic Republic of Congo, this study aims to understand the dynamic of a typhoid fever (TF) outbreak and to assess: a) the existence of hot spots for TF transmission and b) the difference between typhoid cases identified within those hot spots and the general population in relation to socio-demographic characteristics, sanitation practice, and sources of drinking water. Methods: This was a retrospective analysis of TF outbreaks in 2011 in Kikwit, DRC using microbiological analysis of water sources and a structured interview questionnaire. Results: There were a total of 1430 reported TF cases. The outbreak's epidemic curve shows earliest and highest peak attack rates (AR) in three military camps located in Kikwit (Ebeya 3.2%; Ngubu 3.0%; and Nsinga 2.2%) compared to an average peak AR of 0.6% in other affected areas. A total 320 cases from the military camps and the high burden health areas were interviewed. Typhoid cases in the military camps shared a latrine with more than one family (P
