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.enSI-SI-SEIR Avian In uenza A(H7N9)Epidemic ModelArticle
