Fig. 2: Estimated viral load curves for symptomatic SARS-CoV-2 Delta patients with different age and vaccination status.

The solid lines are the estimated viral load curves with the best-fit population parameters for different ages (20 and 60 years old) and vaccination status. The light-shaded areas are 95% prediction intervals, which were determined by simulating 1000 parameter sets. The red dotted line is the infectiousness threshold of Ct = 25 (106.11 copies/mL).
