Summary statistics providing the inner 50% and 95% CIs and medians (all rounded to the nearest day) for the estimated number of days an outbreak is delayed (compared to a baseline of no contact tracing and no screening) given one arriving infection per week at the introduction of an intervention consisting of a combination of traveller screening and sensitisation and contact tracing.
