Figure 3

Distributions, based on 10,000 simulations, of the time delay, T20, given reproduction number (R0) = 1.5 and the peaked infectivity function, with 99% travel restrictions imposed in scenario 1 (A) and (B) and scenario 2 (C) and (D). Scenario 1 simulates an epidemic beginning in Sydney and spreading to Melbourne. In scenario 2, the epidemic begins in Darwin and spreads to Sydney. In (A) and (C), the restrictions are imposed after 2 weeks; in (B) and (D), they are imposed after 4 weeks.
