摘要: 目的:探讨血吸虫病抽样调查居民感染率及感染者例数的推算方法。方法:结合多重分层整群随机抽样方法的特点,应用血吸虫病流行病学和医学统计学原理,对居民感染率及感染者例数的统计方法进行理论推导。结果:得出各流行省及其不同类型未控制流行区的居民感染率及感染者例数的1套理论计算公式。结论:推算方法简明、合理,有实际应用价值。

Abstract: AIM:To offer the method of calculating infection rate and number of infected persons in nation wide sampling investigations on schistosomiasis japonica. METHOD: Calculation formulae were established on the basis of schistosomiasis epidemiology and biomedical statistics, adopting multiple stratified cluster sampling. RESULTS: Thirteen formulae were derived for calculation of infection rate and number of infected persons in different endemic provinces with different types of endemic areas. CONCLUSION: The presented method is simple, rational and available.
