the awareness effect of the dynamical behavior of sis epidemic model with crowley-martin incidence rate and holling type iii treatment function

This article deals with the dynamical behaviors for a biological model of epidemic diseases with holling type iii treatment function. a crowley-martin formula to transmission of disease with coverage media programs effect on the population are introduced and investigated. through some basic analyses, an explicit formula for the basic reproduction number of the model is calculated, and some results such as the stability analysis and instability of all equilibrium points for the model are established. the local bifurcation occurs near all equilibrium points for the model under some special cases that are studied. the numerical simulations are executed to confirm the theoretical results.
