Effect of Interventions. Panel A shows basic reproduction number (R0). Left Panel: under combinations of different levels of contact tracing (with a mean time of two days from onset of symptoms to isolation) and surgical mask-wearing (or social distancing); Right Panel: without surgical mask-wearing or social distancing. Panel B shows the daily number of new domestic infections under containing efforts using a combined strategy: (1) test-and-isolation and contact tracing: taking an average of 2 days from the onset of symptoms to isolation, and tracing 75% contacts of detected cases; plus (2) halving social contacts or half of the people wearing surgical mask, with daily importation of 1, 5, or 10 infected persons (in incubation period). Panel C shows the cumulative numbers (of detected cases) needed to isolate or hospitalize (upper Panel) and the cumulative numbers (of contacts) needed to quarantine (lower Panel) during the period from Day 1 to Day 90, with daily importation of 1, 5, or 10 infected persons in incubation period.
