摘要
We study an SEI endemic model with a general contact rate. constant recruitment and disease-caused death. The basic reproduction number is found. By constructing suitable Liapunov function and using Lasalle invariance principle, it is proved that the disease-free equilibrium is globally stable and the disease dies out eventually. The sufficient condition is established to ensure that the unique endemic equilibrium is globally stable. Numerical simulations support our analytical conclusions.
