一类具有可变易感性的更新传染病模型的全局稳定性

Global stability properties of a class of renewal epidemic models with variable susceptibility

Michael T. Meehan, Daniel G. Cocks, Emma S. McBryde

摘要:

研究了一类具有可变易感性的更新型传染病模型的全局动力学性质。我们证明了在这个扩展的模型中存在唯一的地方病平衡点,并证明了当$R_0 > 1$,即当它存在时,它是全局渐近稳定的。我们还证明了无感染平衡点是全局渐近稳定的,它总是存在的,$R_0 \leq 1$。

英文摘要:

We investigate the global dynamics of a renewal-type epidemic model with variable susceptibility. We show that in this extended model there exists a unique endemic equilibrium and prove that it is globally asymptotically stable when $R_0 > 1$, i.e. when it exists. We also show that the infection-free equilibrium, which exists always, is globally asymptotically stable for $R_0 \leq 1$.
