1970~2013年金湖县血吸虫病流行态势与防治效果

目的  了解金湖县血吸虫病流行趋势和防治效果，探讨防治策略和防治措施。 方法  收集金湖县1970~2013年血吸虫病防治资料，对不同年代和不同时期血吸虫病情、螺情以及所采取的防治策略、防治措施进行回顾性分析。 结果  金湖县1970 年起开展血吸虫病防治工作，属血吸虫病轻度流行区。历经传播控制、传播阻断、巩固监测等不同防治阶段，采取相应的防治策略，有效控制了血吸虫病的流行，1997 年达到血吸虫病传播阻断标准，现已连续23年未发现本地感染的粪阳病人、病畜。至2013年底，累计查螺面积278 407.07hm2，发现有螺面积3 420.98hm2。环境改造灭螺面积60.96hm2，药物灭螺和巩固性灭螺面积8 820.94hm2 ，有螺面积下降了99.64%。累计查病503 265 人次，发现血吸虫病人1 785例，查畜41 114头次，发现病畜397 头。治疗血吸虫病人2 795人次，病畜468头次。 结论  金湖县已有效控制了血吸虫病的传播，但钉螺复现和新发现螺区时有发生，而且存在输入性传染源，极易引起血吸虫病重新传播流行，应加强本地监测和巩固工作。

Endemic trend and control effect of schistosomiasis in Jinhu County from 1970 to 2013

Objective To understand the endemic trend and control effect of schistosomiasis in Jinhu County,so as to explore schistosomiasis control strategy and control measures.Methods The schistosomiasis control data in Jinhu County from 1970 to 2013 were collected,and the schistosomiasis prevalence,snail status and control strategy in different years and periods were analyzed retrospectively.Results The control work of schistosomiasis in Jinhu County had been carried out since 1970,and the county belonged to mild endemic areas.After went through different control stages,namely transmission control,transmission interruption,and consolidation and monitoring,and position—relevant control strategies were taken,schistosomiasis in Jinhu County had been effectively controlled,and had reached the criteria of schistosomiasis transmission interruption in1997,there had no local schistosome infection patients and domestic animals which were positive by fecal examination been found for 23 consecutive years.By the end of 2013,there were around 3 420.98hm^2 snail infested areas found in 278 4Q7.07hm~2 investigated areas.The area with snail control by carrying out environmental modification and by using molluscicides was 60.96hm2 and 8 820.94hm^2,respectively,and the area with snails had reduced by 99.64%.A total of 1 785 schistsosmiasis cases were found in 503 265 people,and a total of 397 head domestic animals were determined as schistosome infection in 41 114 ones.In addition,2 795 schistosomiasis patients and 468 head of infected domestic animals were treated.Conclusion Schistosomiasis in Jinhu County has been effectively controlled,but the emerging and reemerging snail area is occasionally discovered,and there are imported schistosomiasis cases,which may easily cause the revival of schistosomiasis transmission,so the surveillance and the control achievement consolidation should be strengthened.
