Epidemic spreading in community networks
EUROPHYSICS LETTERS 15 October 2005 Europhys. Lett., 72 (2), pp. 315-321 (2005),-0001,():
Social networks have the structure of communities. To understand how the community structure affects epidemic spreading, we present a simplified model of community network, and investigate the epidemic propagation in this model. We find that, compared to the random network, the community network has a broader degree distribution, a smaller threshold of epidemic outbreak, and more prevalence to keep the outbreak endemic. The formulae of epidemic threshold are given and confirmed by numerical simulations.
