Comparison of the effect of three different control measures in the age-structured compartmental model. The three measures, school closure, school closure and social distancing, work distancing (coloured continuous lines, from left to right), act on the structure of the matrix (see text). For reference, the dashed lines result from an intervention reducing infectivity but yielding the same effective $R_0$ during the intervention. Epidemic values are $({\gamma }_E,{\gamma }_I)=(1/7,1/14)$. Vertical dashed lines indicate beginning and end of control
