Empirical distribution of delays from swab collection to case notification from COVID-19 cases notified in the Australian state of New South Wales between 1 July 2020 and 1 February 2021.
Fig 2.
Interview delay distributions for twelve combinations of different prioritisation strategies and interview capacities. A delay of zero days means that cases were interviewed on the same day their notification was confirmed by the health authority. If the delay exceeds five days, the interview is missed.
Fig 3.
Estimated reduction in transmission for different combinations of interview prioritisation strategy and interview capacity as a percentage of the mean incoming case number. The reduction is the overall effect of the test-trace-isolate-quarantine system, where we assume 100% compliance with isolation and quarantine.
