Abstract :
This paper is concerned with global analysis of a delay SVEIR epidemiological model in a population of varying
size. By using Lyapunov stability method and LaSalle’s invariance principle for delay systems, we prove that
when there is no endemic equilibrium, the disease free equilibrium is globally asymptotically stable, otherwise the
endemic equilibrium is globally stable.
