CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishWe study the global behavior of a nonlinear 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 in [d'Onofrio et al., Theor. Pop. Biol., 71, 2007] and, at same time, give a special example of application of the geometric method for global stability, due to M. Li and J. Muldowney. Numerical investigations are provided to show how the stability properties depend on the interplay between some relevant parameters of the model.
