Appendix Figure 2

Mean number of exported cases from 50,000 simulations. Parameters are as in Figure 2, with assortative mixing (φ = 0.25) and initiating the epidemic among high-frequency fliers. A ) Effect of varying relative frequency of flying in high-frequency travelers with that in low-frequency fliers (f = 1, 10, 20, and 100. B) Effect of varying proportion of the population in the high-frequency traveling group (r = 0.000001, 0.00001, 0.0001, 0.001, 0.01, and 0.1.
