Query: Spatial correlations in SIR epidemic models   We investigate the role of global mixing in epidemic processes. We first
construct a simplified model of the SIR epidemic using a realistic population
distribution. Using this model, we examine possible mechanisms for destruction
of spatial correlations, in an attempt to produce correlation curves similar to
those reported recently for real epidemiological data. We find that
introduction of a long-range interaction destroys spatial correlations very
easily if neighbourhood sizes are homogeneous. For inhomogeneous
neighbourhoods, very strong long-range coupling is required to achieve a
similar effect.
