摘要: 目的:为全国血吸虫病抽样调查居民血吸虫感染度的总体参数建立统计学方法。方法:应用血吸虫病流行病学的实践经验,结合分层整群随机抽样方法的实际,对未控制流行地区居民血吸虫感染度的计算方法进行理论推导。结果与结论:推导并给出居民血吸虫感染度的算术均数和几何均数的理论公式。理论公式具有实际应用价值。

Abstract: AIM: To set up statistical methods for calculation of intensity of schistosome
infection in residents in nationwide sampling survey of schistosomiasis. METHODS: Based on the
epidemiological survey of schistosomiasis and according to the medical statistics for multiple
stratifying and clustering random sampling,the calculation method on intensity of schistosome
infection was inferred. RESULTS AND CONCLUSION: Nine formulas were worked out for the
calculation of the intensity of schistosome infection in different endemic provinces with different ecotypes. These formulas are of practical value.

Key words: Schistosomiasis, sampling survey, intensity of infection, mean
