摘　　要：[Objective]To predict prevalence of fleas via a simple epidemiological model.[Method]The field investigation was carried out in 23 locations in Yunnan Province.A simple epidemiological model was involved mean abundance and variance of abundance.[Result]The prevalence of fleas increased with their mean abundance in logistic curve.A linear correlation of the predicted prevalence against observed prevalence did not differ significantly from unity.[Conclusion]Prevalence could be explained simply by their mean abundance.[目的]预测褐家鼠体表蚤的感染率。[方法]在云南省的23个县(市)进行现场抽样,采集褐家鼠体表蚤,运用包涵平均感染度及方差的流行性模型。[结果]蚤感染率与感染度的对数值成线性相关,蚤感染率的预测值与实际值成线性相关。[结论]褐家鼠体表蚤的平均感染度可以预测其感染率。
