FIG. 6.

Probability of infection ${\mathcal{P}}_{cd}$ for droplet route d at different cutoff droplet sizes (implying no droplets beyond that size) for (a) as a function of time measured from the instant of the beginning of the expiratory event and (b) as a function of distance measured from the location of the origin of the expiratory event along the center of the jet/puff trajectory. T_∞ = 21.44 °C and RH_∞ = 50%. ρ_v = 7 × 10⁶ copies/ml with $t_{d\frac{1}{2}}=t_{n\frac{1}{2}}=t_{\frac{1}{2}}$, where $t_{\frac{1}{2}}=15.25$ min.
