Testing, tracing and isolation in compartmental models
Fig 7
Pathological parameter values.
This plot shows the effect of very low levels of testing, θ = 50−1days−1. In this circumstance, the number of traceable susceptible individuals takes on unphysically high values, shown by the red line in the top left panel. This results in an overestimation of the maximum number of unconfined exposed and infectious individuals and a corresponding underestimation of the effect of contact tracing in preventing infection in this scenario.
