Abstract
We study the spread of disease in an SIS model for a structured
population. The model considered is
a time-varying, switched model, in which the parameters of t
he SIS model are subject to abrupt change.
We show that the joint spectral radius can be used as a thresho
ld parameter for this model in the spirit
of the basic reproduction number for time-invariant models
. We also present conditions for persistence
and the existence of periodic orbits for the switched model a
nd results for a stochastic switched model.
