Fitted breaking points were placed on day 9.8 (15/3/20, estimated infection on 23/2/20) and 20.7 (26/3/20, estimated infection on 5/3/20) (Figure 4) . The growth rate of the number of cases decreased by 56% (from 0.22 to 0.10) after the first breakpoint (15/3/20) and decreased again by 65% (from 0.10 to 0.03) after the second breakpoint (26/3/20). The model with one slope shift (on day 12.4, i.e. 17/3/20, estimated infection on 25/2/20) and one intercept shift (on day 8.2, i.e. 13/3/20, estimated infection on 21/2/20) showed a marginally significant improvement of goodness-of-fit relative to Model 2 (0.10
