综合治理快速控制血吸虫病效果观察

目的探索血吸虫病快速控制方案。方法采用喷粉灭螺新技术、快速筛查化疗技术,并辅以环境改造和健康教育等组合措施作为快速控制血吸虫病的综合防治方案,在现场实施并观察其防治效果。结果依托新技术的综合防治方案实施后,2005-2008年连续4年无感染性钉螺,且未发现血吸虫急性感染病例;活螺密度由2004年的1.48只/0.1m^2下降至2008年的0.71只/0.1m^2;有螺面积由2004年的43.13hm^2下降至2008年的33.68hm^2;人畜查病阳性率均下降至0。结论实施喷粉灭螺和快速筛查化疗等新技术为核心的综合防治方案可以快速有效控制、乃至阻断血吸虫病的流行。

Fast control effect on schistosomiasis of comprehensive measures

Objective To evaluate the effect of the fast control scheme of schistosomiasis.Methods The fast control scheme of schistosomiasis was carried out,and the scheme mainly included dusting molluscicide,rapid immunodiagnosis screening and chemotherapy with praziquantel,environment modification,health education,etc.The control effects of the scheme were observed longitudinally.Results There were no infected snails found after the scheme was implemented from 2005 to 2008.The densities of living snails dropped from 1.48 snails/0.1 m~2 in 2004 to 0.71 snails/0.1 m~2 in 2008.The areas with snails dropped from 43.13 hm~2 in 2004 to 33.68 hm~2 in 2008.The infection rates of residents and cattle dropped to 0 in 2008.Conclusion The fast control scheme of schistosomiasis can control schistosomiasis fast.
