主 题:scale-free network awareness vaccination epidemic threshold
摘 要:This paper presents a modified susceptible-infected-recovered(SIR) model with the effects of awareness and vaccination to study the epidemic spreading on scale-free networks based on the mean-field *** this model,when susceptible individuals receive awareness from their infected neighbor nodes,they will take vaccination *** theoretical analysis and the numerical simulations show that the existence of awareness and vaccination can significantly improve the epidemic threshold and reduce the risk of virus *** addition,regardless of the existence of vaccination,the awareness can increase the spreading threshold and slow the spreading speed *** a given awareness and a certain spreading rate,the total number of infections reduces with the increasing vaccination rate.
