In this paper, we study a new SEIRS epidemic model describing nonlinear incidence with a more general form and the transmission of influenza virus with disease resistance. The basic reproductive number ₀ is obtained by using the method of next generating matrix. If ₀<1 , the disease-free equilibrium is globally asymptotically stable, and if ₀>1 , by using the geometric method, we obtain some sufficient conditions for global stability of the unique endemic equilibrium. Finally, numerical simulations are provided to support our theoretical results.
