Global stability of an SEIQV epidemic model with general incidence rate

In this paper, a class of SEIQV epidemic model with general nonlinear incidence rate is investigated. By constructing Lyapunov function, it is shown that the disease-free equilibrium is globally asymptotically stable if the basic reproduction number ℛ0 ≤ 1. If ℛ0 > 1, we show that the endemic equilibrium is globally asymptotically stable by applying Li and Muldowney geometric approach.
