Abstract
Three behavioral-epidemic models (i.e. epidemic systems including feed- backs that the information about an infectious disease has on its spreading) are introduced. Two relevant feedbacks are explicitly considered: the pseudo-rational ex- emption to vaccination and the information–related changes in contact patterns by healthy subjects. The global stability analysis of the endemic states is performed by means of the geometric approach to stability, with particular focus on a model of vaccination of adult susceptible subjects. Biological implications of the results are discussed.File in questo prodotto:
