Fig. 1: Infection rate scenarios.
From: Digital proximity tracing on empirical contact networks for pandemic control

Growth or decrease rate of the number of newly infected individuals, assuming either that all the infected people can eventually be identified and isolated (a); or that only symptomatic people can be isolated with 20% of asymptomatic infected individuals (b); or that only symptomatic people can be isolated with 40% of asymptomatic infected individuals (c). Infection rates are reported as a function of the isolation efficiency εI and the tracing efficiency εT. In all the three settings the cases are reported with a delay of 2 days.
