2005-2011年江陵县国家血吸虫病监测点疫情监测

目的 掌握2005-2011年江陵县国家血吸虫病监测点疫情变化趋势， 为制定全县血吸虫病防治策略提供参考依据。方法 根据 《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， 对7年的病情和螺情指标进行统计分析。结果 与2005年相比， 2011年江陵县国家血吸虫病监测点人群、 耕牛血吸虫感染率分别从 1.83%和11.67%下降到0.91%和0， 活螺密度、 感染性钉螺密度和钉螺感染率分别由4.02、 0.014 5只/0.1 m2 和0.36%下降到 0.70、 0.000 3只/0.1 m2 和0.04%。7年间， 监测点建沼气池183户， 建无害化厕所193座， 进行扩大化疗634人次， 救治晚期血吸虫病人66人次， 药物灭螺总面积为83.67 hm2 ， 开展学生健康教育2 160人次， 发放宣传单 （画）2 746张， 出板报48期， 在有螺环境竖立警示牌45块。结论 江陵县血吸虫病疫情呈逐年下降趋势， 但仍处于不稳定状态。需加大以控制传染源为主的综合防治措施的实施力度， 防止疫情反弹。

Surveillance of endemic situation of schistosomiasis in a national surveillance site in Jiangling County from 2005 to 2011

Objective To understand the dynamics of schistosomiasis japonica in a national surveillance site in JianglingCounty，Hubei Province，China，so as to provide the evidence for formulating the intervention strategy of schistosomiasis controlin the whole county. Methods The surveillance was performed in the surveillance village according to The National SurveillanceScheme of Schistosomiasis japonica，and the results were analyzed statistically from 2005 to 2011. Results The schistosome infec?tion rates in residents and cattle decreased from 1.83% and 11.67% in 2005 to 0.91% and 0 in 2011，respectively. The density ofliving Oncomelania hupensis snails，the density of infected snails，and the infection rate of snails decreased from 4.02/0.1 m2，0.014 5/0.1 m2，and 0.36% in 2005 to 0.70/0.1 m2，0.000 3/0.1 m2，and 0.04% in 2011，respectively. Conclusions The trans?mission of schistosomiasis in the surveillance site shows a gradually decreasing trend year by year，but the prevalence is still notstable. Therefore，the comprehensive interventions with the main effort for the infectious source control still need to be strengthened.
