# Global dynamics of an SIRS model with demographics and transfer from infectious to susceptible on heterogeneous networks

• Received: 29 December 2018 Accepted: 28 April 2019 Published: 19 June 2019
• In this paper, by taking full consideration of demographics, transfer from infectious to susceptible and contact heterogeneity of the individuals, we construct an improved Susceptible-Infected-Removed-Susceptible (SIRS) epidemic model on complex heterogeneous networks. Using the next generation matrix method, we obtain the basic reproduction number $\mathcal{R}_0$ which is a critical value and used to measure the dynamics of epidemic diseases. More specifically, if $\mathcal{R}_0 < 1$, then the disease-free equilibrium is globally asymptotically stable; if $\mathcal{R}_0>1$, then there exists a unique endemic equilibrium and the permanence of the disease is shown in detail. By constructing an appropriate Lyapunov function, the global stability of the endemic equilibrium is proved as well under some conditions. Moreover, the effects of three major immunization strategies are investigated. Finally, some numerical simulations are carried out to demonstrate the correctness and validness of the theoretical results.
