The dots present a typical traditional SIR model run with \(\beta = 0.2\), \(\gamma = 0.1\) (\(R_0 = 2\)), and one initial infection. The solid lines correspond to \(\beta _{\mathrm {eff},0} \simeq 0.7\), i.e \(R_0 \simeq 7 \), \(k = 1... 30\), one infection for a superspreader in the \(k=10\) bin, and \(\alpha = 2.5\) for the initial distribution. This model is our fiducial NSIR model and it is displayed with dots for reference the set of epi curves that follow
