Figure 6

Average epidemic size as a function of σ and τ−1 in heterogeneous (left) and homogeneous (right) subpopulation networks. Each figure shows via a color map the average percentage of subpopulations affected by the outbreak in the space of σ and τ−1. The lower the commuting rate the longer the visiting time is needed for the infection to spread to a finite fraction of subpopulations. The figure should be compared with the phase diagrams of Fig. 4. Networks are composed of V = 104 subpopulations, each of which with a degree-dependent population of N̄k = N̄k/〈k〉 residents with N̄= 104. Disease is characterized by R0 = 1.25 and μ−1 = 15 day.
