Schematic representation of the Metapopulation System.
A population of individuals is divided into V subpopulations connected with each other following a heterogeneous network. Within each subpopulation, individuals are classified according to their dynamical status as Susceptible (S), Infected (I) and Removed (R). In absence of behavioral changes (blue arrows), individuals move from a subpopulation to another at a rate λ following the shortest path connecting both subpopulations. The discontinuous arrows represent the second mechanism of behavioral reaction in which people travel avoiding places with high prevalence at the cost of larger diffusion paths.
