FIG. 10.

SEIRD-droplet/nuclei model output with computed rate constants mentioned in Table II for case IA. No lockdown and free mixing are assumed. (a) Case IA, no mask usage and (b) case IB, all I wear masks from the (i) 100th day and (ii) 30th day of the onset of the pandemic that prevents the ejection of D_s,0 > 10 µm droplets with ρ_v = 7 × 10⁶ copies/ml. Calculated rate constants are shown in Table II for cases IA and IB. The masks for this case are assumed to prevent the ejection of all particles greater than 10 µm.
