Abstract: Objective To understand the dynamics of schistosomiasis japonica in a national surveillance site in Honghu City， Hubei Province， China， so as to provide the evidence for formulating the intervention strategy of schistosomiasis control in the whole City. Methods The surveillance was performed in the surveillance village according to The National Surveillance Scheme of Schistosomiasis japonica， and the results were analyzed statistically from 2005 to 2013. Results The schistosome infection rates in residents and cattle decreased from 1.76% and 20.93% in 2005 to 0 in 2013， respectively. The density of live Oncomelania snails decreased from 4.20/0.1m2 to 0.17/0.1m2， respectively. No infected snails were found during the period of 9 years in succession. The total area with molluscicidal drugs was 68.38 hm2 in the monitoring sites during the period of 9 years， and the expanded chemotherapy was performed of 634 person?times. Sixteen （person?time） advanced schistosomiasis patients received the treatment and salvation. The health education was carried out in students （3 836 person?times）. Totally 5 685 leaflets of health education were distributed， and 17 bulletin boards of health education were performed. Five warning boards were set up at the environments with snails. Conclusion The transmission of schistosomiasis in the surveillance site in Honghu City shows a gradually decreasing trend year by year. However， the surveillance and control of snails still should be strengthened.

摘要： 目的 分析2005-2013年洪湖市国家血吸虫病监测点疫情变化态势，为制定全市血吸虫病防治策略提供参考依据。方法 按照《全国血吸虫病监测方案》的要求，每年在监测点开展人畜查治病、查灭螺和相关因素监测，并对9年间病情和螺情指标进行统计分析。结果 与2005年相比较，2013年洪湖市国家血吸虫病监测点人群、耕牛血吸虫感染率分别由1.76%和20.93%下降到0，活螺平均密度由4.20只/0.1 m2下降到0.17只/0.1 m2，连续9年未发现感染性钉螺。9年间，监测点药物灭螺总面积为68.38 hm2，扩大化疗634人次，救治晚期血吸虫病人16人次，对学生开展血防健康教育3 836人次，发放宣传单（画）5 685张，办宣传栏板报17期，在有螺环境竖立警示牌5处。结论 洪湖市国家血吸虫病监测点血吸虫病疫情已呈低度流行态势，下一步应加强螺情监测与控制工作。
