Table 2.

A list of estimated parameters values to be used in our simulations.

Parameter	Value	Reference
$β_{A}$	Calibrated to 0.86 so that $R_{0} = 1.4$ when $h_{2} = 0.5$ and $R_{0} = 5.6$ when $h_{2} = 0$ .	See Section 2.2
$∊_{A}$	$[0, 1]$ as social distancing decreases contacts. Calibrated, as described for $β_{A}$ , to 0.12.	See Section 2.2
$∊_{S}$	Assumed equal to $∊_{A}$	See eqn. (40)
$β_{I}$	$β_{I} = 2 ∊ β_{A}$ , assuming symptomatics stay at home (so distancing them has same impact as distancing asymptomatics) and are twice as infective as asymptomatics. Recall $∊ ≔ ∊_{A} = ∊_{S}$ .	Li et al. (2020)
$h_{2}$	Varied in manuscript. Units are per day.	See Section 2.2
$γ_{AI}$	$0.296$ (per day).	Ferguson et al. (2020)
$γ_{IR}$	$0.048$ (per day).	WHO (2020)
$f$	$[0, 1]$ , using $0.65$ .	COVID-19, 2020
$δ$	$2.4 \times 10^{- 3}$ (per day).	Worldwide mortality figures on 03/29/2020 from Dong et al. (2020)
