Cumulative positive cases (as proportion of the total population) at half a year. RT-PCR with return delay $\ell =1$ days (dark blue), $\ell =2$ days (light blue) and testing capacity $C=0.1$; Ag test with return delay $\ell =0.5$ days and testing capacity $C=1$ (red), $C=0.5$ (orange), $C=0.33$ (maroon), and $C=0.1429$ (magenta). All other parameters and initial conditions are given in Table 1 and Table 2.
