Model differences depending on τ , n and β. Subfigures a-c show the difference in the total outbreak size between a pure random mixing model and a model assuming complete repetitiveness (without clustering) relative to the population size N. Contour plots are interpolated from a grid of measurement points using Microsoft® Office Excel 2003. (a) infectious period: 2 ≤ τ ≤ 14, step width (sw): sw = 1; daily number of contacts: 4 ≤ n ≤ 20, sw = 2; per-contact transmission probability: β·n·τ = 1.6. (b) 1.2 ≤ β·n·τ ≤ 4.0, sw = .2; 4 ≤ n ≤ 20, sw = 2; τ = 14. (c) 1.2 ≤ β·n·τ ≤ 4.0, sw = .2; 2 ≤ τ ≤ 14, sw = 1; n = 4.
