The SEIR epidemic model studied here includes incorporates constant recruitment, disease-caused death and disease latency. The incidence term is of the saturating contact rate form. A threshold R0 is identified which determineds the outcome of the disease; if R0 <=1, the disease-free equilibrium is globally stable and disease dies out, while if R0 > 1, a unique endemic equilibrium is globally asymptotically stable in the interior of the feasible region and the disease will persist at the endemic equilibrium if it is initially present.
Keywords:Epidemic models; Global stability; Latent period;
