本文探讨了我省淮河上游洪水型钩体病流行区，自１９８１年该地人群停止钩体菌苗预防接种后，加强防治知识的宣传教育，传染源的管理，群众实施堆肥发酵，改变散放为圈猪积肥，猪的圈养率达８１１３％，减少猪之间相互感染，猪钩体带菌率由７０年代的８７６％降为１８９％〈４／２１２〉Ｐ＜０．０１；人群隐性感染率由２２３５％也降为１９４％Ｐ＜０．０１。改变猪散放为圈养的饲养方式，是行之有效的控制传染源的措施，从而控制本病的发生和流行 This article explores the upper reaches of the Huaihe River flood Leptospirosis endemic areas, since 1981 the population stopped leptospirosis vaccination, strengthen the prevention and treatment of publicity and education, source of infection management, the implementation of the compost fermentation, change the release For lap pig manure, the captive rate of pigs was 81.13%, which reduced the mutual infection between pigs. The infection rate of pig leptospira was reduced from 8.76% in the 1970s to 1.89% <4/212> P <0. 01; the latent infection rate in the population was also reduced from 2235% to 194% P <0.01. Changing the way pigs are housed for captive feeding is an effective measure to control the source of infection so as to control the occurrence and prevalence of this disease
