Figure 1

Black continuous lines represent the daily incidence of COVID-19 for the Lombardy from 02/24/2020 up to 02/24/2021. Color vertical lines indicate the starting time of different containment measures, which combines lockdown restrictions and closures with measures such as testing policy and contact tracing, etc. We adopt a color code ranging from red, orange, yellow up to green as a rough indicator of the severity of these restrictions, decreasing from red to green, i.e strong restrictions are imposed in the temporal period after a red line whereas weak ones after a green one. Magenta diamonds represent the result of numerical simulations implementing the best estimate for \(\{R_c\}\) and \(\{\mu \}\), for \(\tau =0.15\), \(a=6.2\tau \), provided by the LL maximization procedure. The overlap with experimental data is achieved setting \(I(0)=250\).
