Analysis of the Dynamics of SI-SI-SEIR Avian In uenza A(H7N9) Epidemic Model with Re-infection

Abstract

The spread of Avian in uenza in Asia, Europe and Africa ever since its emergence in 2003, has been endemic in many countries. In this study, a non-linear SI-SI-SEIR Mathematical model with re-infection as a result of continuous contact with both infected poultry from farm and market is proposed. Local and global stability of the three equilibrium points are established and numerical simulations are used to validate the results.
