	<span style="line-height:1.5;">In this paper, a modified </span><i style="line-height:1.5;">SIS</i><span style="line-height:1.5;"> (susceptible-infected-susceptible) model with infective medium
and feedback mechanism on scale-free networks is presented. The model is suited to describe some epidemic spreading which are not only transmitting by
medium but also spreading between individuals by direct contacts. Considering
biological relevance and people¡¯s subjective consciousness, we introduce medium
and feedback to describe the epidemic spreading. By mathematical
analysis, we obtain the epidemic threshold and equilibriums.
Simulation shows that the medium parameter can
change the threshold, and the bigger it is, the
easier epidemic breaks. Feedback parameter cannot change the&nbsp;basic reproductive
number, but it can reduce the endemic level and weaken the epidemic
spreading.</span>
