Abstract: Objective Objective To understand the schistosome infection situation of mobile population in Xiuzhou District. Meth Meth? ? ods ods The data about the distribution of mobile population from the counties not reaching schistosomiasis transmission controlled in Xiuzhou District were collected，then the questionnaire survey combined with laboratory detection were used to investigate the situation of imported schistosomiasis in this district. In addition，the average infection rate and the estimated number of schisto? somiasis patients were calculated. Results Results From 2013 to 2014，there were 15 940 people from the counties not reaching schis? tosomiasis transmission controlled in Xiuzhou District，among which，4 405 were investigated，and 124 of them had schistosomi? asis and treatment history. Thirty?eight people were positive in serological tests，and 3 cases were positive in the etiological de? tection. The average infection rate of schistosome of the mobile population in Xiuzhou District was 0.068%，the calculated num? ber of schistosomiasis patients was 11. Conclusions Conclusions The imported sources of infection are the main risk for the consolidation of the results of schistosomiasis control，which may result to the rebound of the endemic situation. So the management and surveil? lance of mobile population should be strengthened.

摘要： 目的 目的 了解秀洲区流动人口血吸虫感染情况。方法 方法 收集2013-2014年秀洲区自血吸虫病未传播阻断县输入 的流动人口的分布情况， 采用问卷调查与实验室检测相结合的方法调查流动人口血吸虫感染情况， 计算流动人口血吸虫 感染率， 并推算输入性病例数。结果 结果 2013-2014年秀洲区自全国未传播阻断县输入的流动人口数为15 940人， 共调查 4 405人， 其中有血吸虫病史及治疗史者124人。共查出血清学阳性38例， 病原学阳性3例； 血吸虫平均感染率为 0.068%， 推算输入性病例数为11人。结论 结论 输入性传染源是影响传播阻断地区血防成果巩固及导致疫情回升的主要隐 患， 应加强流动人员管理及监测。
