Figures

Fig 1
Fig. 1
Distribution of RT-qPCR cycle threshold (Ct) of nasopharyngeal swabs, nasal swabs, and saliva specimens collected at baseline (A) and day 7 (B). Cts correspond to the viral RNA-dependent RNA polymerase (RdRP) gene.
Fig 2
Fig. 2
Correlation of the viral load (VL) of nasopharyngeal swabs with that of nasal swabs and saliva specimens at baseline (A) and day 7 (B). Viral loads were estimated using a calibration line obtained with serial dilutions of SARS-CoV-2 control RNA, run in parallel to a set of samples covering all thermal cycles used in the analysis. Negative samples (in red) were assigned to a Ct of 40 (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.).
