摘要

摘要医院传染病是指在卫生保健机构内不同类型易感个体之间传播的传染病。为了模拟这种类型的流行病，我们使用具有多元负二项后代分布的多类型分支过程。特别地，我们估计了基本繁殖数r0 {R_{0}}，并研究了它与后代分布参数的关系。在单一类型流行病的情况下，我们研究了接触者追踪对r0 {R_{0}}估计值的影响。

Multi-Type Branching Processes Modeling of Nosocomial Epidemics

Abstract Nosocomial epidemics are infectious diseases which spread among different types of susceptible individuals in a health-care facility. To model this type of epidemics, we use a multi-type branching process with a multivariate negative binomial offspring distribution. In particular, we estimate the basic reproduction number R 0 {R_{0}} and study its relationship with the parameters of the offspring distribution. in case of a single-type epidemic, we investigate the effect of contact tracing on the estimates for R 0 {R_{0}} .
