Host mobility plays a fundamental role in the spatial spread of infectious diseases. Previous
theoretical works based on the integration of network theory into the metapopulation
framework have shown that the heterogeneities that characterize real mobility networks
favor the propagation of epidemics. Nevertheless, the studies conducted so far assumed the
mobility process to be either Markovian (in which the memory of the origin of each traveler is
lost) or non-Markovian with a fixed traveling time scale (in which individuals travel to a …
