Abstract--Understanding human mobility is crucial for mod-
eling the spatial spread of human infectious diseases. The quanti-
tative description of spatial epidemics is based on two prominent
theoretical approaches, diffusive dispersal and direct coupling
or effective force of infection. The first ansatz assumes random-
walk movement of the host between different locations whereas
the second employs an effective force of infection between
distinct populations. Both models are inconsistent with important
