The spreading of diseases based on scale-free networks considering the individual self-protection

Considering people´s self-protection behavior when coming across with diseases, we make a study of the spreading of diseases on the basis of the BA scale-free networks, using the classical SIS model. We figure out the individual self-protection behavior by reconnection of the statistic broken-edge and the dynamic broken-edge. The study proves that strengthening the individual self-protection awareness has an obviously effect on the suppression of diseases and saving the expense of the immunization. When considering the individual´s self-protection character marked by the dynamical evolution of contact edges, the spreading of diseases have a character of a periodical and peak-decreasing multi-wave infection.
