摘　　要：Ｋａｔｏ法是用于社区血吸虫病普查的诊断方法。然而，对同一病人的重复检查显示不同Ｋａｔｏ片的虫卵计数存在较大的差异，因此，仅检查一片Ｋａｔｏ片将导致大量的漏检，从而低估疾病流行率。提出了一个基于Ｐｏｉｓｓｏｎ分布的数学模型，用于估计Ｋａｔｏ法的漏检率。Kato assay is a diagnostic method used in the mass survey of schistosoma infection. However, repeated examination in one individual shows considerable variation in egg counts. A large fraction remains undetected if only one slide is examined, which leads to underestimation of prevalence. In this study, a mathematical model based on Poisson distribution was proposed to estimation of the missing rate. This model is tested against empirical data from Jishan, Jiangxi province.
