Abstract: An age-structured SIRS epidemic model with screening strategy and infectionage is  formulated. The basic reproductive number is defined. Global stability of equilibria   of the model are disucssed by constructing suitable Lyapunov functions.

Key words: globally asymptotical stability, infection-age, SIRS epidemic model
