Scenarios and Parameter Adjustments for a Number of Policy-based Interventions to Curtail COVID-19 in Jail and the Community

Scenario Name	Parameters	Multiplier of Baseline	Scenario Description
Shelter in place	$\beta {}_{*}^{\text{C}}$	0.4	Effective contact rate in the community is reduced by a factor of 1/2.5
Arrest reduction
Bail eligible	${\alpha }_{\text{L}}$, ${\alpha }_{\text{H}},$${\alpha }_{\text{E}}$	0.75	Divert all bail-eligible arrests (estimated at 25% of all arrests)
Vulnerable only	${\alpha }_{\text{H}}$, ${\alpha }_{\text{E}}$	0.10	Divert arrests of 90% of vulnerable populations11
Low level	${\alpha }_{\text{L}},$ ${\alpha }_{\text{H}},$ ${\alpha }_{\text{E}}$	0.17	Divert all low-level arrests (estimated at 83% of arrests)
Arrest fewer people	${\alpha }_{\text{L}},$ ${\alpha }_{\text{H}},$ ${\alpha }_{\text{E}}$	0.10	Divert 90% of current arrests
Faster release
Increase release speed	${\rho }^{-1}$	2	2× rate of release from jail
Vulnerable only	${\rho }_{\text{H}}^{-1}$	2	2× rate of release for vulnerable only
In-jail scenarios
Mixing reduction	${\beta }_{\text{T}},$ ${\beta }_{\text{P}},$ ${\beta }_{\text{J}}$	0.4	Reduction of baseline contact rates in jails by the same factor as the community under shelter-in-place
Reduced detection	$\zeta$	0.99, 0.95, 0.90	Reduction in infection detection and timely hospitalization in jails by $1-\zeta$
