Phys. Rev. Lett. 109, 128702 (2012) [5 pages]Localization and Spreading of Diseases in Complex NetworksReceived 19 February 2012; revised 24 April 2012; published 19 September 2012 Using the susceptible-infected-susceptible model on unweighted and weighted networks, we consider the disease localization phenomenon. In contrast to the well-recognized point of view that diseases infect a finite fraction of vertices right above the epidemic threshold, we show that diseases can be localized on a finite number of vertices, where hubs and edges with large weights are centers of localization. Our results follow from the analysis of standard models of networks and empirical data for real-world networks. © 2012 American Physical Society URL:
