Testing, tracing and isolation in compartmental models

Fig 6

Comparison of differential equation and agent-based model.

Here the population size is 10000 individuals with 100 initially infected. The testing rate is θ = 7⁻¹days⁻¹, and tracing rate and success probability are χ = 0.5, η = 0.5. The plots show the time-series for each compartment. The top row are the compartments representing unconfined individuals, those in S_U, E_U, I_U and R_U. The bottom row are those representing isolated—diagnosed or distanced—individuals, S_D, E_D, I_D, R_D. The heavy orange curves are the output of the ODE-based simulation. The teal curves are the average output of the agent-based simulation, with envelopes for one and two standard deviations.
