Proportion of infectious individuals as a function of β and R 0. Curves represent the endemic equilibria according to the homogeneous system (1) (full line) and the heterogeneous system (3) (dashed line), using parameter values specified in Table 1. Estimates of β and R 0 for the same proportion of infectious individuals under both models are marked (dotted lines).Back to article page
