(a) Total number of confirmed cases of Covid-19 in Italy, F(t) (red dots), reported in Ref.¹², up to 25th April 2020, compared with the deceased cases, $R_{D} (t)$ (blue dots), in the same period of time. If the numbers of dead persons are shifted in time by $T_{d} ≃ 4$ days and rescaled by $γ^{- 1} = 7$ (blue circles) they perfectly overlap with the total numbers of cases. The blue solid line is theoretical prediction for F(t), as solution of Eq. (30). (b) Daily number of infected persons, $Δ F (t)$ (red dots), and daily number of victims $Δ R_{D} (t)$ (blue dots). The blue circles are the daily number of victims after rescaling according to Eq. (34), with $T_{d} = 4$ days and $γ = 1 / 7$ . The solid blue line is $\frac{d F (t)}{dt}$ from the solution of Eq. (30).
