在基本消灭血吸虫病地区应用环卵沉淀反应和酶标记抗原对流免疫电泳对219～453名粪检阴性包括有血吸虫病史者和无血吸虫病史者进行了连续五年的血清流行病学调查,结果表明两种血清学方法检测特异性抗体水平的动态变化,可反映流行区的疫情趋势、考核防治效果、提高病人检出率,有综合查病的诊断价值。
Serological epidemiological investigation of 219 ~ 453 persons with history of schistosomiasis, including history of schistosomiasis and no history of schistosomiasis, was carried out for five consecutive years by serological and immunoprecipitation in the area of eliminating schistosomiasis. The results showed that Two kinds of serological methods to detect the dynamic changes of specific antibody levels can reflect the epidemic trend of endemic areas, test the effect of prevention and treatment to improve the detection rate of patients with a comprehensive diagnosis of diagnostic value.
