Figure 14From: The impact of digital contact tracing on the SARS-CoV-2 pandemic—a comprehensive modelling studyThe sensitivity of the outcomes to the size and the structure of the simulated population is shown. The three population structures (described in Sect. 2.1) correspond to the homogeneous population with a gamma distribution (Eq. (3)) describing the number of contacts per day, a homogeneous distribution using the power law (Eq. (4)) for the number of contact per day, and the social graph population. Settings are \({R_{0}}=3\), \({\alpha }\cdot {f_{m}}=0.6\), \({\eta _{\mathrm {DCT}}}=1\), trace uninfected = true. For the 10,000 people population, outcomes have large statistical fluctuations and error bars show the error on the mean. For the other points, the error bars are smaller than the marker sizeBack to article page
