FIG. 5.

Probability of infection ${\mathcal{P}}_{c\beta }$ for droplet route d and dried droplet nuclei route n, as well as total probability ${\mathcal{P}}_{\beta }$ 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%. The bold lines represent 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. The gray shaded region denotes the lower limit $t_{n\frac{1}{2}}=0.01t_{d\frac{1}{2}}$ and upper limit $t_{n\frac{1}{2}}=100t_{d\frac{1}{2}}$, respectively, with $t_{d\frac{1}{2}}=t_{\frac{1}{2}}$.
