From: Time-continuous and time-discrete SIR models revisited: theory and applications
Time-varying transmission rates from real-world data and from parameter estimation for short-term prediction of German data with \(t_{1} = 0\) (1 March 2020) and \(t_{M} = 62\) (2 May 2020). The estimated parameters for model 1 are \(\alpha _{1} \approx 0.3194\) and \(\alpha _{2} \approx 0.003911\). For model 2, we fix \(\alpha _{1} = 1.0\) and choose \(\alpha _{2} \approx 0.070\)
