Fig. 2From: Estimation of timing of infection from longitudinal SARS-CoV-2 viral load data: mathematical modelling studyViral load dynamics of the three patients in China. The three panel presents timeline of infection for the three cases in Zhuhai, China used to compute the viral load boundary for infection establishment. Expected SARS-CoV-2 viral dynamics and observed viral load are depicted by grey (or black) solid lines and grey open circles, respectively. The timing of symptom onset (black dashed lines), the timing of infection establishment (known; blue shaded areas), and the estimated viral load boundaries for infection establishment (red dashed lines) are also shownBack to article page
