Table 1. Selected simulation model parameter values and sources.

Parameter (notation)	Description	Values or distribution	Reference
β 1	Transmission probability per contact of senior females	[0.006,0.02]	Estimated from parameter fitting
$S_{{\beta }_1}$	Scale factor for β1, transmission probability relative to that of senior females (which means transmission probability per demo-group is ${\beta }_1\times S_{{\beta }_1}$)	[0,1]	Estimated from COVID sex and age disaggregated data of [26]
β 2	Proportion of infected agents that eventually show symptoms	0.45	[27]
TA→I TA→R	Duration of asymptomatic period until symptoms start to show (if the next state is I), or until agents recover (if the next state is R)	If the next state is I, lognormal(1.63,0.52); If the next state is R, lognormal(2.23,0.22); Cut off at 21 days.	[28],[29]
τA	The day when an asymptomatic case become infectious	If the next state is I, 2 days before turning into I, or day 1; If the next state is R, day 3.	[30],[31],[29]
β 3	Proportion of symptomatic cases that result in death	[0,0.1]	[26]
TI	Duration of symptomatic infection	lognormal(2.04,0.42); Cut off at 21 days.	[32]
