Global stability of an SIR epidemic model with information dependent vaccination. (English)
[J] Math. Biosci. 216, No. 1, 9-16 (2008). ISSN 0025-5564

Summary: We study the global behavior of a nonlinear susceptible-infectious-removed (SIR)-like epidemic model with a non-bilinear feedback mechanism, which describes the influence of information, and of information-related delays, on a vaccination campaign. We upgrade the stability analysis performed by {\it A. d'Onofrio, P. Manfredi} and {\it E. Salinelli} [Vaccinating behavior, information, and the dynamics of SIR vaccine preventable diseases. Theor. Popul. Biol. 71, No. 3, 301--317 (2007; Zbl 1124.92029)] and give a special example of the application of the geometric method for global stability, due to {\it M. Y. Li} and {\it J. S. Muldowney} [SIAM J. Math. Anal. 27, No.~4, 1070-1083 (1996; Zbl 0873.34041)]. Numerical investigations are provided to show how the stability properties depend on the interplay between some relevant parameters of the model.
