In this paper, we propose a novel space-dependent multiscale model for the spread of infectious diseases in two-dimensional spatial context on realistic geographical scenarios. The couples system kinetic transport equations describing population commuters moving large scale (extra-urban) with diffusion characterizing non-commuting acting over small (urban). modeling approach permits to avoid un...
