Hosts heterogeneities and spatial spread.
Human behavior displays many degrees of heterogeneity. Contact patterns among individuals, frequency and duration of travels, topology of transportation systems and fluxes of travelers, as well as many other aspects related to human interactions and mobility are shown to be broadly distributed and to largely fluctuate among different classes of individuals.
Great part of epidemic modeling studies are based on simplifying assumptions typically relying on homogeneous approximations regarding some of the aspects mentioned above. Our theoretical research work in this area seeks to go beyond these simplifications aimed at reaching an understanding of the impact of the observed heterogeneities on the spatial propagation of an infectious disease.
