| Abstract: | A disease transmission model of SI type with stage structure is formulated. The stability of disease free equilibrium, the existence and uniqueness of an endemic equilibrium, the existence of a global attractor are investigated. |
| Keywords: | SI epidemic model threshold disease free equilibrium endemic equilibrium global attractor |
