目的评价实施以传染源控制为主的综合防治措施以来,防治血吸虫病效果。方法收集枞阳县2008-2014年人群查病、急性感染、耕牛查病、钉螺调查、健康教育、改水改厕、淘汰耕牛等资料,统计分析有关疫情变化。结果 2004~2008年枞阳县人群血吸虫病感染率由2.62%降至0.42%,耕牛血吸虫病感染率由2.38%降至0,急性感染仅发生6例,2013年后无急性病例;钉螺感染率逐年下降,2013年后未查到感染性钉螺,但活螺密度降低不明显。结论枞阳县实施以传染源控制为主的综合防治措施后,血吸虫病疫情得到有效控制。但当地流行因素复杂,钉螺面积大,需继续坚持综合防治措施,巩固防治成果。
Objective To evaluate the effectiveness of schistosomiasis control since the implementation of comprehensive prevention and control measures based on infection source control. Methods The data of epidemic situation in the populations of Zongyang County during 2008-2014 were collected, including epidemic disease, acute infection, cattle disease investigation, snail investigation, health education, water improvement and toilet renovation, elimination of cattle and other data. Results The infection rate of schistosomiasis in Zongyang County from 2004 to 2008 decreased from 2.62% to 0.42%. The infection rate of schistosomiasis in cattle decreased from 2.38% to 0. Only 6 cases were acute infection and no acute cases occurred after 2013. Rate decreased year by year, no infectious snails were found after 2013, but the live lobed density was not significantly reduced. Conclusion After the implementation of comprehensive prevention and control measures in Zongyang County, which is mainly controlled by infection sources, the epidemic situation of schistosomiasis has been effectively controlled. However, due to the complicated epidemic factors and the large snail area, it is necessary to continue adhering to comprehensive prevention and control measures and consolidate the results of prevention and treatment.
