The total number of infected persons (excluding successfully vaccinated infected contacts) depends on A, the number of index cases starting the epidemic, and B, the day of the infectious period after which the diagnosis of the first case occurs. The time to extinction is shown for C, different numbers of index cases and D, the day of the infectious period after which the diagnosis of the first case occurs.
