目的 研究血吸虫病中度流行区人群询诊初筛再 IHA查治策略的费用 -效果。方法 将鄱阳湖沿岸人群血吸虫感染率为 10 %左右的 10个自然村随机分为过筛组和普查组 ,分别实施人群询诊过筛后 IHA检查和 IHA普查 ,阳性者化疗 ,分析两组的费用与效果。结果 过筛组询诊阳性率5 8.90 % ,使 41.10 %的阴性人群不作 IHA查病 ,较普查组节省 34.0 4%的查病费用 ,两组化疗费用相近 ,防治效果相似。成人粪检阳性者中 97.97%询诊阳性 ,儿童则只有 5 2 .94% ,符合率成人高于儿童。结论 在血吸虫病中度流行区 ,成人询诊过筛再 IHA查病具有实用价值 ,对儿童则仍以 IHA普查化疗为宜。
Objective To study the costs-effectiveness of screening, screening and screening IHA strategies in people with moderate prevalence of schistosomiasis. Methods Ten natural villages with a prevalence of 10% of schistosomiasis in the coast of Poyang Lake were randomly divided into screening group and screening group. IHA screening, IHA screening, positive chemotherapy, With effect. Results The positive rate of inquiry in screening group was 5 8.90%, 41.10% of the negative population did not get IHA, which saved 34.0% of the cost of the disease investigation. The cost of the two groups was similar and the control effect was similar. 97.97% of the positive cases of adult fecal examination were positive for inquiry, while only 52.294% of children were eligible, and the coincidence rate was higher in adults than children. Conclusion In endemic areas of schistosomiasis, it is of practical value for adults to screen for screening for IHA and for IHA for children.
