目的评价湖北省以传染源控制为主的血吸虫病综合防治措施初期实施效果。方法在湖北省4个疫情较重的血吸虫病流行县(市、区),选择8个疫情较严重的流行村(项目村)为试点,开展改水改厕、建沼气池、安全用水、耕牛淘汰等以传染源控制为主的血吸虫病综合防治措施,调查项目实施后的血吸虫病疫情控制效果。结果项目实施1～2年后,8个项目村改厕和建沼气池覆盖率、安全用水覆盖率和耕牛淘汰率分别为37.1%、65.9%和18.4%;人群血吸虫感染率下降了71.99%,耕牛血吸虫感染率下降了70.66%,阳性螺密度下降了76.75%,钉螺感染率下降了58.97%。结论实施以传染源控制为主的综合防治措施可以有效控制血吸虫病流行。
Objective To evaluate the initial implementation of the comprehensive prevention and control measures for schistosomiasis in Hubei Province. Methods Four epidemic counties (cities and districts) with severe epidemic situation of schistosomiasis in Hubei Province were selected as experimental sites, and eight epidemic villages (project villages) with severe epidemic situation were selected as experimental sites. Water and sanitation latrines, biogas digesters, safe water use, Cattle elimination and other sources of infection control of schistosomiasis control measures to investigate the project implementation of schistosomiasis control effect. Results After 1 ~ 2 years of project implementation, the coverage of lavatories and biogas digesters in the 8 project villages was 37.1%, 65.9% and 18.4% respectively; the infection rate of the population decreased by 71.99% , The infection rate of schistosomiasis dropped by 70.66%, the positive spiral density decreased by 76.75%, and the infection rate of snails decreased by 58.97%. Conclusion The implementation of comprehensive control measures based on infection source control can effectively control the epidemic of schistosomiasis.
