一个新的具有地方病平衡点的易感-传染(SI)模型

A New Susceptible-Infectious (SI) Model With Endemic Equilibrium

摘要:

本文的重点是一个新的易感感染模型,其中包括一个易感组($S$)和两个不同的感染组($I_1$和$I_2$)的动力学。一旦被感染,个体就成为具有不同临床感染形式的这些感染性群体之一的成员。此外,在疾病进展期间,$I_1$群中的受感染个体可传递到具有更高死亡率的传染性$I_2$群。在这项研究中,该模型的解的正性证明。研究了物种灭绝、无$I_1$平衡点、地方病平衡点和无病平衡点的稳定性。研究了该病的基本繁殖数与各侵染阶段基本繁殖数之间的关系。在特定条件下对该模型进行了研究,得到了其精确解。

英文摘要:

The focus of this article is on the dynamics of a new susceptible-infected model which consists of a susceptible group ($S$) and two different infectious groups ($I_1$ and $I_2$). Once infected, an individual becomes a member of one of these infectious groups which have different clinical forms of infection. In addition, during the progress of the illness, an infected individual in group $I_1$ may pass to the infectious group $I_2$ which has a higher mortality rate. In this study, positiveness of the solutions for the model is proved. Stability analysis of species extinction, $I_1$-free equilibrium and endemic equilibrium as well as disease-free equilibrium is studied. Relation between the basic reproduction number of the disease and the basic reproduction number of each infectious stage is examined. The model is investigated under a specific condition and its exact solution is obtained.
