Before revision:  These\langle \rangle\lesssim \langle \rangle results suggest that the early containment of the disease within China was close to optimal and could not have been significantly improved upon .
After revision:  These\langle \rangle, we get intermediate power-law growth exponents that are in general agreement with available data from China. On the other hand, we obtain a quadratic growth for smaller step sizes l\lesssim \langle \rangle results suggest that the early containment of the disease within China was close to optimal and could not have been significantly improved upon .
