| 根据多年来获得的钩端螺旋体病人群发病率、感染率及宿主动物带菌率等调查资料,结合有关地理气候文献对地理层次及气候的划分指标,将云南省钩端螺旋体病的地理立体分布划为三层来认识,发现其分布流行规律是:低热层为重度流行层,发病率高达229~626/10万,感染率26~30%;中暖层发病率在100/10万左右,感染率12~14%,为中度流行层;高寒层为轻度流行层,发病率﹤0/10万,感染率0.8~6.0%。海拔高度与发病率、感染率分布呈反比关系;海拔高度与发病率作相关回归分析,结果显示密切的直线负相关(r=-0.964),以感染率为指标作相关回归分析,呈高度的曲线负相关(r=-0.987),进一步阐明了钩体病的地理立体分布流行规律,为防治提供科学依据。 |

| According to the morbidity and infection rate in human, the pathogen carrying rate of reservoir animals and refer to the geographic weather and altitudes, the Stereoscopic distribution of leptospirosis may be divided into three different geographic levels in Yunnan. Their epidemic rules are:The areas of hot weather and low altitude are heavy epidemic level where the morbidities of leptospirosis are as high as 229~626/100000, and the infection rate of human being is 26~30%. The areas of temperate weather and middle altitude are epidemic level of moderate degree. Those areas have a morbidity about 100/100000 and infection rate of 12~14%. The areas of cold weather and high altitude are epidemic level of light degree. Those areas have a morbidity smaller than 10/100000 and infection rates between 0.8% and 6.0%. The geographic altitude has a relationship of reverse ratio with the distribution of morbidity and infection rate of leptospirosis. The result of altitude and morbidity analysed by interelation regression shows close linear negative interrelation (r=-0.964), Interrelation regression with the infection rate analysis shows highly cubic negative interrelaion (r=-0.987). This further demonstrates the epidemic rules of different geographic distribution of leptospirosis. |
