Analysis of a SIRS model with self-protection

An improved SIRS model combined with awareness of self-protection based on the existing model with nonlinear incidence according to the fact that the network nodes would take protective measures under virus attack which changed the structure of network was proposed; The asymptotic stability of system under the protective measures was analyzed by Liapunov stability theory; How the protective measures influenced on the spread of virus on uniform network is showed through the compared simulation. By analyzing the improved SIRS models we have obtained that under the non-disease state, self-protection plays less of a role; To the opposite, the self-protection play a big part in epidemic spreading. The final number of infections will be reduced by self-protection under the epidemic state.
