## Abstract We study the stability of a delay susceptibleβinfectiveβrecovered epidemic model with time delay. The model is formulated under the assumption that all individuals are susceptible, and we analyse the global stability __via__ two methodsβby Lyapunov functionals, andβin terms of the varia
