Modeling spatial spread of communicable diseases

It is natural to ask how spatial movement of the hosts affects the spatial-temporal spread pattern of the disease if the basic reproduction number for an otherwise homogeneous population exceeds unity. Answers to the above question obviously depend on the manner in which hosts move in ...
