Fig. 8

Plots of the social-distancing switching (applied only to class \(\hbox {S}_\text{r}\)), social-relaxation switching (applied only to class S), and the disease-induced natural mortality switching (applied only classes I and \(\hbox {I}_\text{r}\)) functions obtained from MLE fits of the relevant parameters to the first 100 days of Israeli incidence and mortality data (see Fig. 7) are shown over the interval March 1 to August 18. The onset values for these three switching functions are days 4 (March 5), 74 (May 14), and 0 (March 1) respectively. The switching points (half way between initial and final values, although the switching time can precede the onset time, as discussed in Section A.3 and caption to Fig. A.2, Additional file 1) are on days 6 (March 7), 38 (April 8) and 4 (March 3) respectively. The range of initial to final values are indicated by the values that scale the vertical axes of the three curves in question
