Figure 12From: The impact of digital contact tracing on the SARS-CoV-2 pandemic—a comprehensive modelling studyThe effect of incubation time (IT) and tracing order (TO) for different tracing delays. IT = 7 refers to the curve with mean incubation period of 7 days, and IT = 4 to the one with mean incubation period of 3.6 days. The yellow point shows results for the alternate transmission probability curve (IC) as shown in Tab. 1 (grey values). Predictions from the “age-of-infection” (AOI) model, where only infected contacts are traced, are shown as the dark green line for parameters IT = 7, TO = 1 - the result shown is not exact (see Suppl. Materials). This is for \({ p_{\mathrm {app}}}=0.75\), \({\eta _{\mathrm {DCT}}}=1\), and \({\alpha }\cdot {f_{m}}=0.6\)Back to article page
