A kind of epidemic model having infectious force in both latent period and infected period. (Chinese. English summary) Zbl 1059.92509

Summary: An SEIRS model having infectious force in the latent period is discussed in this paper. Conditions and thresholds for the existence of various equilibria are established. By means of linearizing and the Lyapunov-LaSalle invariant set theorem, we obtain stability results for various equilibria. The simultaneous influence of the latent period and infective period to the disease is exposed.
