From: The impact of travelling on the COVID-19 infection cases in Germany
Estimation of cumulated infections in Germany compared to Johns Hopkins University from 1 June to 31 August with three piecewise constant travel impact rates \(\alpha\), on the left side the number of infections, on the right side the death cases. The shaded area represents the SACI interval. The dashed line describes the simulation with \(\alpha =0\), i.e. either no travelling is allowed or the traveller compartment had been completely free of the disease
