Global Stability of Multigroup Dengue Disease Transmission Model

الملخص EN

We investigate a class of multigroup dengue epidemic model.

We show that the global dynamics are determined by the basic reproductive number R0.

We present that when R0≤1, there is a unique disease-free equilibrium which is globally asymptotically stable; when R0>1, there exists a unique endemic equilibrium and it is globally asymptotically stable proved by a graph-theoretic approach to the method of global Lyapunov function.
