摘要
目的 探讨估计寄生虫感染的常用流行病学指标的数学模型。方法 利用数学模型的方法对寄生虫感染的各主要环节进行模拟 ,以建立适当的数学模型。结果 对寄生虫感染的负二项分布理论、雌雄异体的寄生虫的配对及产卵、基本再生率、密谋依赖效应等基础问题进行了详细的讨论 ,并重点就用感染率资料预测人群中发病危险性的模型和估计实际感染率的模型进行了深入探讨。
Objective To study the mathematical models for estimating epidemiological measurements of parasitic infections.Methods A mathematical model was used to imitate major process of parasitic infections. Results Negative binomial distribution, mating and egg production of female worms, basic reproduction rate and density dependent effect were discussed. Mathematical model for estimating the risk of disease incidence by the data of infections and the model for estimating true prevalence were discussed and developed.Conclusion Mathematical models can be used to estimate the major epidemiological measurements of parasitic infections.
