摘要
目的评价以传染源控制为主的综合防治措施在湖北省血吸虫病流行区的3年防治效果,为湖沼型血吸虫病流行区防治提供经验。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(试点村),开展改厕和建沼气池、安全用水、耕牛淘汰、兴林抑螺等以传染源控制为主的血吸虫病综合防治措施,辅以常规卫生血防措施,对血吸虫病疫情变化及居民人均收入等进行分析。结果经过3年的综合防治,与试点工作前比较,试点村钉螺面积下降17.51%,活螺平均密度下降14.22%,阳性螺密度下降77.21%,钉螺感染率下降73.47%;平均人群血吸虫感染率下降86.38%;家畜存栏头数下降,耕牛血吸虫感染率下降88.01%;人均收入较试点前增加40.78%。结论实施以传染源控制为主的综合防治措施可有效控制湖沼型血吸虫病流行,社会效益与经济效益显著。
Objective To evaluate the effectiveness of comprehensive measures to control schistosomiasis primarily through infection source control over 3 years in Hubei Province. Methods Eight villages（pilot villages） in 4 counties（districts） of Hubei Province with a high incidence of schistosomiasis were selected as study sites to investigate the effectiveness of comprehensive schistosomiasis control measures including ＂improved latrines and methane-generating pits＂,＂safe water supply＂,＂cattle culling＂,and ＂tree planting to deter snails＂.Schistosomiasis control measures were also supplemented by routine hygiene-related measures.Data on schistosomiasis morbidity and residents＇ per capita income were analyzed. Results After 3 years of comprehensive control measures,areas where snails were found decreased 17.51%,the density of living snails decreased 14.22%,the density of infected snails decreased 77.21% and the rate of snail infection decreased 73.47%.The rate of schistosome infection in residents decreased 86.38%.The number of livestock declined and the rate of infection in cattle decreased 88.01%.Residents＇ per capita income increased 40.78%. ConclusionComprehensive measures to control schistosomiasis primarily through infection source control were feasible and effective in schistosome-endemic marshlands and had obvious social and economic benefits..
