Figure 6.

Epidemiological risk metrics as a function of the relative length of mild infections (${\gamma }_{\mathrm{s}}/{\gamma }_{\mathrm{m}}$). The panels correspond to those in figures 4 and 5, but with different vertical axis ranges. The graphs were generated by varying ${\gamma }_{\mathrm{m}}$ while fixing all other parameters at their default values. The estimated values of ${\mathcal{R}}_0$ (listed in table 2) are associated with the ratio of generation intervals listed in table 3 (${\gamma }_{\mathrm{s}}/{\gamma }_{\mathrm{m}}=T_{\mathrm{gen},\mathrm{m}}/T_{\mathrm{gen},\mathrm{s}}=(3.3+9)/(3.3+14)=0.71$).
