Fig. 2: Distribution of the numerically derived individual (PCFD) and global risk of infection (RCFD) for the venues with displacement (DVV), mixing (MVV) and natural (NVV) ventilation considering a high emitting individual (90th percentile).

From: Comparing strategies for the mitigation of SARS-CoV-2 airborne infection risk in tiered auditorium venues

Fig. 2

Infection risk plots for the venue with displacement ventilation (a), mixing ventilation (b) and natural ventilation (c) are shown, considering a high emitter. a At DVV, the emitter was located at H5 (I), E6 (II) and B9 (III). b MVV emitter positions were at I16 (I), E16 (II) and H28 (III). c The positions of the NVV emitters were at J20 (I), E5 (II) and A14 (III). The individual risk of infection is plotted for each position, except for the red positions, as these do not represent seats in the audience. The sum of risks for each venue and emitter position as well as the number of spectators with the acceptable risk of infection Racc > 1% are indicated above the plots.
