Global stability of an SIR epidemic model with time delay. (English)
[J] Appl. Math. Lett. 17, No. 10, 1141-1145 (2004). ISSN 0893-9659

Here, the authors study an SIR epidemic model with time delay in the variable I (infected and infectious). They deal with the persistence of the system and derive lower limits for each population. They derive sufficient conditions for the global stability of the endemic (internal) equilibrium state. They find that the delay affects both persistence and global stability of the system.
