Limiting factors for the spread of infectious diseases in complex networks — •Hartmut H K Lentz1,2, Mario Konschake2, and Igor M Sokolov1 — 1Department of Physics, Humboldt University, Newtonstr. 15, 12489 Berlin, Germany — 2Friedrich-Loeffler-Institut, Institute of Epidemiology, Seestr. 55, 16868 Wusterhausen, Germany
Epidemics are expected to spread rapidly in networks with heavy-tail degree distributions. On the other hand, many real world networks comprise complex substructures like modules. Modules are subsets of nodes being densely interconnected. This yields subgraphs which are in the limiting case 'isolated' from each other. Furthermore the directed character of a network might play a role in disease spread. Most social and human networks can be treated as undirected. But many networks, e.g. trade networks, are inherently directed since there is an underlying economic/logistic process. In directed networks the number of possible ways for a pathogen is dramatically reduced. Our results show that direction and community structure are limiting factors for disease spread.
