Fig. 27.

Later effects of interventions on G₁, G₂, for $\eta =0.013$: Top: G₁and all interventions. Bottom G₂ and all interventions. The curves are qualitatively similar to $\eta =0.009,$the period between second and further peaks differ from those on Figs. 25 and 25. The first peak is not affected by the change of η (below 2% change in height, that could be also due to statistical error margins, so we omit to plot it. The first peak of the red curve (corresponding to truncating long edges) is the first peak of the epidemic.
