FIG. 3.

Comparison between analytical predictions [Eq. (4)] and simulation results for the fraction $R^{*}$ of recovered nodes after which quarantine becomes less convenient than preventive immunization. The dashed line indicates perfect equality. Simulations are performed on Erdös-Rényi (ER) networks with various values of the average degree $〈k〉$ and on a scale-free (SF) network. Error bars are not shown when smaller than symbols size. System size is $N={10}^5$.
