The effect of changes in the initial number of infections on epidemic profiles. Simulations for the time-courses of epidemic (total number of infections without isolation: I + IT + Ir + IT,r) using parameter values given in Table 1. Other parameters are: (a,b) R0 =1.9; p = 0.72; q = 0.71; Tc = 22.2% and initial infected cases of (a) E0 = 6 (three infection waves) and (b) E0 = 12 (single infection wave); (c,d) R0 = 2.5; p = 0.55; q = 0.41; Tc = 26% and initial infected cases of (c) E0 = 8 (single infection wave) and (d) E0 = 10 (two infection waves).
