Schematic for a mathematical model of COVID-19 in a linked urban community-jail system with parameter annotations. Left: Depiction of model emphasizing movement between locations. Here “Court” stands for both processing and trials. Right: Depiction of the model emphasizing transition between disease states. The parameter family is shown for each type of transition. For example, although we show just one $\alpha$ between community and court, in our model, there are separate subscripted $\alpha$ parameters corresponding to different rates of arrest for different age groups. Similar logic applies to the other parameters. E indicates exposed; I, infected; M, needing medical care; R, recovered/removed; S, susceptible.
