A) The logistic function [2, 3, 4] (LF ) (Fig. 1) describing the evolution of a given population N (τ ) of N 0 individuals at τ = 0 (in the present case infected people) in an environment with carrying capacity K and growth rate r, is specified by Before considering a more elaborated point of view, we consider the data from "Regione Lombardia" only, where we have reported the relevant logistic curve (Fig. 6 ). A final element of discussion comes from Fig. 14 where we have reported the worldwide and Italian evolution of the Covid cases/day 2 , a kind of bi-logistic pattern is evident, which supports the ideas put forward in this and in the previous note.	./cache/cord-166918-hop33fxg.txt	./txt/cord-166918-hop33fxg.txt
