Degree-correlaed vaccination in aymmetric interacting spreading dynamics

Abstract

Recently, the asymmetric interacting spreading of disease and disease information has attracted much attention. Most of existing studies have assumed that the individuals have the same response (i.e., the same immune probability) when they are aware of the disease. Here we introduce a model of degree-correlated vaccination behavior in the asymmetric interaction of disease and disease information spreading. By extensive simulations, it finds when the vaccination probability is more positive correlated with individual's degree, the inhibition effect of disease information on the spread of disease become less effective. We also find there exists an optimal correlation between the vaccination probability and individual's degree which can inhibit the spread of disease more effectively.
