Competing epidemics on complex networks
Human diseases spread over networks of contacts between individuals and a substantial body of recent research has focused on the dynamics of the spreading process. Here we examine a model of two competing diseases spreading over the same network at the same time, where infection with either disease gives an individual subsequent immunity to both. Using a combination of analytic and numerical me...
متن کاملEffective distances for epidemics spreading on complex networks.
We show that the recently introduced logarithmic metrics used to predict disease arrival times on complex networks are approximations of more general network-based measures derived from random walks theory. Using the daily air-traffic transportation data we perform numerical experiments to compare the infection arrival time with this alternative metric that is obtained by accounting for multipl...
متن کاملEpidemics on Interconnected Networks
Populations are seldom completely isolated from their environment. Individuals in a particular geographic or social region may be considered a distinct network due to strong local ties but will also interact with individuals in other networks. We study the susceptible-infected-recovered process on interconnected network systems and find two distinct regimes. In strongly coupled network systems,...
متن کاملModelling Epidemics on Networks
Infectious disease remains, despite centuries of work to control and mitigate its effects, a major problem facing humanity. This paper reviews the mathematical modelling of infectious disease epidemics on networks, starting from the simplest Erdös-Rényi random graphs, and building up structure in the form of correlations, heterogeneity and preference, paying particular attention to the links be...
متن کاملEpidemics on Small-World Networks
This paper reviews the use of graphs as mathematical descriptions of social networks, and discusses in particular some properties of the commonly used random (Erdős-Rényi), small-world (Watts-Strogatz) and scale-free (power-law) models, with particular focus on the small-world model. The applications of such networks to epidemiology are then briefly outlined with some comments pertaining to the...
