目的 比较湖沼型血吸虫病重度流行区2种不同防治策略的效果,为优化血吸虫病重疫区防治策略、控制疫情提供参考。方法 选择同类型的2个村,分别采取健康教育+扩大化疗与综合防治对策2种不同策略,用粪检方法检查人群感染率,按流行病学方法调查钉螺面积,根据当地用工及血防费用情况计算投入,进行5年对比分析。结果 健康教育+扩大化疗与综合防治村的人群感染下降率、钉螺面积下降率、年人均防治费用投入分别为73.6 5 %和6 6 .31%、14 .2 0 %和4 0 .6 0 %、5 .98元和19.81元。结论 健康教育+扩大化疗策略疫情下降明显,且年人均投入少,可在垸内湖沼型血吸虫病重疫区推广应用。
Objective To compare the effects of two different control strategies in schistosomiasis endemic areas of lakes and swamps, and to provide reference for the prevention and control of severe and severe epidemic diseases in schistosomiasis. Methods Two different villages of the same type were selected and adopted two different strategies of health education, expansion of chemotherapy and comprehensive prevention and treatment measures. The fecal infection method was used to check the infection rate of the population. The area of snails was investigated according to epidemiological methods. Calculate investment, comparative analysis of 5 years. Results The population infection reduction rate, snail area reduction rate and annual per capita prevention and treatment cost were 73.6 5% and 66.31%, 14.20% and 4.06% respectively in the villages with health education, expanding chemotherapy and comprehensive prevention and cure. , 5.98 yuan and 19.81 yuan. Conclusions The outbreak of health education + expanding chemotherapy strategy decreased significantly, and the annual average per capita input was small, so it can be popularized and applied in the severe flooding area of lakes and swamp schistosomiasis in the embankment.
