Stability Analysis Of Two New Sirs Models With Two Viruses

In this paper, we propose two new kinds of Susceptible, Infective, Removed and Susceptible (SIRS) models with two viruses: continuous SIRS model and discrete-time SIRS model. We obtain sufficient conditions for existence and local stability of the disease-free equilibria and the endemic equilibria in the two models. Moreover, we use numerical simulations to illustrate the validity of our results.
