目的　探索适合浙江省消灭血吸虫病后的监测方案 ,使有限的卫生资源发挥最大的社会经济效益。方法　在奉化、嘉善、衢州、义乌 4个县 (市 )各选择 2个基本条件相类似的乡镇为 A、B两种实验区 ,A区实施《浙江省血吸虫病防治监测巩固技术方案 (试行 ) (1996 )》,B区采用新方案。结果　 A、B两方案最终均能有效地查到钉螺 ,在监测效果上差异无显著性。然而 ,B方案螺情监测的费用投入较 A方案下降 4 5 .4 1%。病情监测均未查到现症病人。结论　已无螺多年的历史流行区 ,可以将轮查时间延长 ,查螺框距适当拉长 ,以不查漏大面积钉螺为度 ,病情监测应以外来传染源为主 Objective To explore a monitoring program suitable for eliminating schistosomiasis in Zhejiang Province so as to maximize the social and economic benefits of limited health resources. Methods Two townships, A and B, were selected in each of the four counties (cities) of Fenghua, Jiashan, Quzhou and Yiwu, and A and B were implemented in A township. The technical scheme of monitoring and consolidating schistosomiasis prevention and control in Zhejiang Province (for Trial Implementation) (1996) ", Area B using the new program. Results A and B both programs can be effectively detected snails, the monitoring effect was no significant difference. However, the cost of program B monitoring dropped by 45.51% from that of program A. Condition monitoring were not found in patients with disease. Conclusions It has been a non-spiral for many years of historical endemic areas, you can extend the round of investigation, check the screw frame properly elongated to not leak large snails for the degree of disease monitoring should be based on external sources of infection
