Figure 4.

Contour plots of the final epidemic size, i.e. the proportion of all the nodes that eventually become infected during the epidemic (continuous lines) and R(∞), i.e. the proportion of all the nodes that were removed by the end of the epidemic (dashed lines). The two plots contrast the case of effective tracing (long latency period and few connections per node) with the case of less effective tracing (short latency periods and many connections per node). The other parameters used were: R₀^MF=3.0, Inf_P=3.5, Tr_P=2.0 and (a) K=5, Lat_P=10.0 and (b) K=20, Lat_P=3.5.
