Key model parameters and quantities.

$\lambda =\frac{\beta I+{\beta }_q{I}_q+{\beta }_c{I}_c}{N}$	force of infection of non-quarantined, self-quarantined & contact-traced infected.
$\varphi$	Proportion of contacts traced & quarantined
$\sigma$	susceptible self-quarantine factor
$p$	probability of transmission upon contact
$\psi =\sigma +\frac{1-p}{p}\varphi$	total susceptible quarantine factor (proportionality constant relative to force of infection)
${\nu }_q$	Relative susceptibility of self-quarantined
${\alpha }_q,{\alpha }_c$	Exit rate from self-, contact-traced quarantine
$\tau$	time to infectious (incubation period)
$T,T_q,T_c$	infectious period (time to isolation) of non-quarantined, self-quarantined, contact-traced
${\mathcal{R}}_{0,b},{\mathcal{R}}_0,{\mathcal{R}}_e$	reproduction numbers (baseline, with contact tracing, effective).
