Table 1.
Preferential Mixing Magnifies the Impact of Heterogeneity in Person-to-Person Contact Rates (activity) on ℜ0. The number of sub-populations and their sizes also affect these results, but here n = 2, N1 = 500 and N2 = 500, so that the mean activity is the same in scenarios A and B. Common parameters: β = 0.05, γ = 1/7, and N1 = N2 = 500 unless otherwise specified in figure or table legends.
| Scenario A | Scenario B | |||
|---|---|---|---|---|
| Parameter | a1 = 10 | a2 = 10 | a1 = 7.5 | a2 = 12.5 |
| ℜ0i | 3.5 | 3.5 | 2.62 | 4.37 |
| ℜ0 (ε1 = ε2 = 0) | 3.5 | 3.72 | ||
| ℜ0 (ε1 = ε2 = 0.5) | 3.5 | 3.88 | ||
| ℜ0 (ε1 = 0.25, ε2 = 0.75) | 3.5 | 3.92 | ||
| ℜ0 (ε1 = 0.75, ε2 = 0.25) | 3.5 | 3.98 | ||
