摘要
目的为了掌握全省血吸虫病流行现状和疫情动态。方法按照全国血吸虫病抽样调查方案要求,采取分层整群随机抽样的方法,共抽取18个样本村,进行人、畜血吸虫感染情况调查和螺情调查;按照居民感染率水平抽取3个村进行体检和B超检查;按照流行类型抽取3个县开展螺情专题调查;选择2个典型水域进行流动人口血吸虫感染情况调查。结果共检查18349人,血清免疫学检查阳性率为14.97%;粪便校正平均感染率为2.23%,病人感染度算术均数(XA)为400,几何均数(XG)为54.41,人群感染度XA为15.37,XG为0.17;男性加权平均感染率为2.77%,女性为1.54%;不同流行类型地区湖汊亚型人群感染率为3.47%、洲滩亚型为3.31%,丘陵亚型为1.12%。水上流动人口血吸虫感染率为4.78%。全省推算病人数为73337人,其中湖汊亚型地区占24.11%,洲滩亚型地区50.5%;丘陵亚型地区占25.39%。黄牛血吸虫感染率为5.0%,水牛感染率为4.98%,猪为0.33%,羊1.92%。结论安徽省血吸虫病疫情仍未得到有效控制,湖沼地区是当前血防工作的重点。
Objective To grasp the prevalence and tendency of schistosomiasis in Anhui province. Methods According to the general demands of national schedule on the survey of schistosomiasis, the methods of stratifying and clustering random sampling technique was used in the survey, and 18 villages were sampled. The people and domestic animal were surveyed for the infection of schistosomiasis. Three villages were selected to take physical and B ultrasound examination by the infection level of people. Two typical water fields were selected to survey the mobile people for the infection of schistosomiasis. Results 18 349 people were examined, and the positive rate of serum immunology was 14.97%, the adjusted average infection rate of people was 2.23%. The arithmetical mean of infectiosity of patients was 400, the geometrical mean of infectiosity of patients was 54.41. The arithmetical mean of infectiosity of population was 15.37, the geometrical mean of infectiosity of population was 0.17. The weight mean of infection rate in males was 2.77% and 1.54% in females. The infection rate was 3.47% in fork-beach subtype, 3.31% in islet without embankment subtype and 1.12% in hilly subtype endemic areas. The infection rate among the mobile people was 4.78%. The estimated number of patients in the province was 73337, of which 24.11% was distributed in fork-beach subtype endemic areas, 50.5% was distributed in islet without embankment subtype and 25.39% in hilly subtype endemic areas. The infection rate of cattle, buffalo, swine, sheep ＆ goat was 5.0%,4.98%,0.33%,1.92% respectively. Conclusion The prevalence situation of schistosomiasis had not been controlled effectively in Anhui province. The marshland and lake endemic regions were still the most emphasis for the control of schistosomiasis in the present.
