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 a constant impact rate \(\alpha\), on the left side the number of infections, on the right side the death cases. Note that, for better visibility, the y-axis does not include 0. The (barely visible) shaded area represents the range of the solutions from the SACI and 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
