Abstract
Abstract
In this paper, a class of discrete SIRS epidemic models with disease courses is studied. The basic reproduction number
R
0
is computed. The main results on the permanence and extinction of the disease are established. That is, the disease-free equilibrium is globally attractive if
R
0
<
1
, and there exists a unique endemic equilibrium and the disease is also permanent if
R
0
>
1
.
