Table 2.

Initial values for the population of frontliners and the general public

State variables	Description	Initial value
		Set 1	Set 2
$S_1$	Number of susceptible from the general public	10,000	100,000
$S_2$	Number of susceptible frontliners	100	1000
$E_1$	Number of exposed from the general public	0	0
$E_2$	Number of exposed frontliners	10	100
$I_1$	Number of infected from the general public	1	10
$I_2$	Number of infected frontliners	0	0
${\text{Is}}_1$	Number of isolated infected from the general public	0	0
${\text{Is}}_2$	Number of isolated infected frontliners	0	0
$R_1$	Number of recovered from the general public	0	0
$R_2$	Number of recovered frontliners	0	0

To identify the effect on the dynamics of the initial value, we consider two sets of initial values for susceptible, exposed, infected, and recovered for the general public and the frontliners
