Epidemic Spread in Adaptive Social Networks with Community Structure

Abstract. When an epidemic spreads in a population, individuals may adaptively change the structure of their social contact network in re-sponse. We study the spread of epidemics in an adaptive network with community structure. Community structure is a characteristic of social networks that has been neglected in previous adaptive network epidemic models. We model the effect of heterogeneous communities on infection levels. We also show how an epidemic can alter the community structure
