Post-lockdown abatement of COVID-19 by fast periodic switching
Fig 9
Sensitivity analysis of the quantity I + D + A + R + T in the SIDARTHE model on quarantine effectiveness q.
(Top) The [2, 12] FPSP policy shows a good stabilising behaviour q ≤ 0.335, corresponding to approximately 66% reduction in infectious contacts during periodic quarantine days whereas a unsatisfactory behaviour is shown for higher values of q (see the trajectory for q = 0.375.) (Bottom). The outer loop action is added to the FPSP policy showing a stabilising behaviour also for q = 0.375.
