Figure 16From: The impact of digital contact tracing on the SARS-CoV-2 pandemic—a comprehensive modelling studyInfluence of social distancing (reduction of the contact rate) and contact tracing on \({R_{e}}\) and \({T_{2}}\). (a) and (c): One-step tracing, (b) and (d) recursive tracing. (a) and (b) \({R_{e}}\), (b) and (d) \({T_{2}}\). Note that in (b) and (c), there is a singularity for \({T_{2}}\) at the line \({R_{e}}=1\), where \({T_{2}}\) becomes infiniteBack to article page
