Dynamic Behavior of SIS Epidemic Model with Feedback on Regular Lattic

In this paper, the dynamic behavior of SIS epidemic model with feedback mechanism on regular lattice is discussed. We investigate the effects of feedback mechanism, crowd density, spread efficiency and the moving activity of individuals on disease spreading by theoretical analysis and computer simulation. The results indicate that feedback mechanism can impact the stable infective ratio of system greatly, moreover, the effect of feedback mechanism in the case of moving crowd is better than that of static crowd, and however, it can not impact the spreading threshold of system. In addition, the results also show that the moving activity of individuals can promote disease spreading under the condition of low crowd density.
