摘要
目的 分析江西省世行贷款血防项目疾病监测结果 ,评估血吸虫病防治效果。方法 在项目覆盖区域 ,采用分层整群随机抽样法选择 5 7个行政村作为疫情监测点 ,1992～ 1998年期间每年开展人群、耕牛及螺情监测 ,对各项监测结果按不同疫区层次纵向比较其年间变化及总体变化趋势。结果 7年来 ,全省一层村所占比例从 1992年的 13.30 %下降至 1998年的 5 .18% ,二层村从42 .88%下降至 2 8.46 % ;全省人群平均感染率和感染度分别下降了 6 0 .89%和 6 2 .86 % ,耕牛感染率下降了 38.74% ,钉螺密度和感染螺密度也有较大幅度下降。结论 江西省血吸虫病流行区通过1992～ 1998年世行贷款血防项目的实施 ,一、二层疫区范围显著压缩 ,人群感染率和感染度大幅度下降 ,全省血吸虫病流行得到了初步控制 ,项目取得了较好的防治效果。
Objective[WT5”BZ] To evaluate the control effect of the World Bank Loan Project for Schistosomiasis Control in Jiangxi Province. [WT5”HZ]Methods [WT5”BZ]57 administrative villages were defined as surveillant spots by using stratified random sampling. the surveillance on residents, cattle and snails was conducted every year from 1992 to 1998, and the results were analyzed to compare the changes of endemicity of schistosomiasis in different endemic areas. [WT5”HZ]Results [WT5”BZ]The proportion of first and second layer endemic villages declined from 13 30% and 42 88% in 1992 to 5 15% and 28 46% in 1998 respectively The reduction of average infection rate and intensity of infection in residents was 60 89% and 62 86% respectively, and 38 74% in cattle, and also density of snails and infected snails decreased greatly [WT5”HZ]Conclusions [WT5”BZ]The ranges of first and second layer endemic areas have been reduced significantly, infection rate and intensity of infection in residents declined greatly and the prevalence of schistosomiasis was controlled basically. So the effective control was obtained due to the implement of the project in Jiangxi Province from 1992 to 1998. [WT5”HZ]
