Age-specific model parameter estimates in Ontario, Canada: Percentage of symptomatic individuals diagnosed, and susceptibility to infection

Parameter	Age class
	0–5	6–13	14–17	18–24	25–64	65+
Percentage of symptomatic individuals diagnosed	31%	38%	37%	20%	64%	67%
Susceptibility to infection	1.9%	1.6%	2.5%	9.2%	13.9%	50.2%

Percentage of symptomatic diagnosed individuals and susceptibility (i.e., probability of infection upon contact, ${\beta }_i$). The reported values are obtained from the mean of the fitting results of 1000 bootstrap realizations. The fraction of symptomatic diagnosed individuals is calculated from $\frac{{\delta }_{I,i}}{{\delta }_{I,i}+{\gamma }_I}$, where ${\delta }_{I,i}$ and ${\gamma }_I$ denote the diagnosis and recovery rate, respectively.
