影响钩端螺旋体病(简称钩体病)流行的因素很多,人群易感性是其中一个主要方面。搞好预防接种,保护易感人群是作为预防钩体病的有力措施。本文引用桃源县1972～1983年钩体病有关资料,分析人群抗体水平与钩体病发病的关系,探索其数学规律。 一、流行病学调查 桃源县的钩体病,1968年经血清学和动物试验证实。1970年全县大流行,发病率高达147.29/10万,1974年至1980年疫情逐年下降,1981年后发病率稍有上升。病例分布在稻田作物区,均有疫水接触史,属
Affect Leptospirosis (Leptospirosis) prevalence of many factors, population susceptibility is one of the major aspects. Doing a good job of vaccination and protection of susceptible people is a powerful measure to prevent leptospirosis. This paper refers to the relevant data of the leptospirosis from 1972 to 1983 in Taoyuan County and analyzes the relationship between population antibody level and the incidence of leptospirosis and explores its mathematical rules. First, the epidemiological investigation of leptospiral disease in Taoyuan County, 1968 confirmed by serological and animal experiments. The county pandemic in 1970, the incidence rate as high as 147.29 / 100,000, from 1974 to 1980 the epidemic decreased year by year, after 1981 the incidence increased slightly. Case distribution in the paddy crop area, have a history of exposure to water, is a genus
