FIG. 7.

The order parameter $r$, as a function of $T$, for real networks: (a) the sexual contact network between Brazilian prostitutes and sex buyers and (b) the friendship network of Gowalla users. Here $f$ is set to $f=0.01$ (open symbols) and 0.2 (solid symbols). The red circles, green triangles, and blue squares represent the results for the quarantine measure, the random vaccination, and the acquaintance vaccination, respectively. The black line represents the result of the original SIR model. The number of nodes is $N=16748$ for the sexual contact network and $N=196591$ for Gowalla network. The data at given $T$ and $f$ are averaged over ${10}^5$ trials.
