摘要
我們探討一個傳染病傳播模型,該模型以傳統流行病學中的「暴露」概念為核心,即個體曾與感染者接觸,但未必已感染。此模型亦納入(離散)的感染年齡結構,從而能間接描述感染者的病毒載量,並進一步定義感染機率如何隨接觸者的病毒載量而變化。

We explore a model of infectious disease spread that incorporates exposure to the pathogen in the classic epidemiological acceptation of the term, i.e., a contact with an infectious individual has taken place but the infection has not necessarily been acquired. The model also includes a (discrete) age of infection structure, allowing to implicitly describe the viral load of infected individuals and in turn, to describe the probability of developing an infection as a function of the viral load of the infectious contacts.
