Fig. 2From: Modeling optimal treatment strategies in a heterogeneous mixing modelThe impact of mixing patterns on the basic reproduction number \(\mathcal {R}_{0}\). The basic reproduction number \(\mathcal {R}_{0}\) is displayed as a function of π 1 and π 2, when activity levels are fixed (a moderate R 0 in the left panel and a higher R 0 in the right panel)Back to article page
