Figure A2.

We plot a comparison between the model (12)–(15) (without public intervention) and the age structured data from Japan. We set $1/\nu =1/\eta =7$ days, $f_i$ which actually depends on the age class, with $f_1=0.1$, $f_2=0.2$, $f_3=0.4$, $f_4=0.4$, $f_5=0.6$, $f_6=0.6$, $f_7=0.8$, $f_8=0.8$, $f_9=0.8$, and $f_{10}=0.9$. and we obtain ${\tau }_1=0.1264$, ${\tau }_2=0.1655$, ${\tau }_3=0.3538$, ${\tau }_4=0.2966$, ${\tau }_5=0.1513$, ${\tau }_6=0.1684$, ${\tau }_7=0.1251$, ${\tau }_8=0.1168$, ${\tau }_9=0.1015$, ${\tau }_{10}=0.1258$. The matrix $\varphi$ is the one defined in (18).
