Fig. 6. Targeted (“perfect”) testing without lockdown.

Strength and duration of the optimal random testing and its impact on the epidemic in case of target testing. (A) The intensity and duration of the targeted testing. (B) Resultant production with respect to initial pre-epidemic production. (C) The relative size of the susceptible population. (D) The number of hospitalized individuals. In each case, we again vary the initiation of testing: two weeks (blue), 4 weeks (yellow), 8 weeks (green), and 16 weeks (red). Values of the economic and epidemiological parameters are described in Table 1 (r = 0, c = 0).
