Figure 2. Time until clearance of severe acute respiratory syndrome coronavirus 2 RNA in any clinical specimens of throat swab, sputum, nasopharyngeal swab, or feces samples among hospitalized patients with coronavirus disease, as estimated with the use of Weibull, Lnorm, and gamma regression, Guangdong, China. A, B) Weibull regression for mild (A) and severe (B) cases; C, D) Lnorm regression for mild (C) and severe cases (D); E, F) gamma regression for mild (E) and severe (F) cases. A total of 43 patients with mild and 6 with severe cases were tested. The medians and 95th percentiles of the time until the loss of detection are indicated; error bars and shading indicate 95% CIs.
