Analysis of SARS-CoV-2 viral load in nasopharyngeal (log₁₀ copies/10,000 cells) and saliva (log₁₀ copies/mL) samples. (a) Repartition of SARS-CoV-2 values for nasopharyngeal and saliva specimens. Pairs for each subjects are connected by lines; (b) SARS-CoV-2 values by testing concordance. The saliva SARS-CoV-2 value was set to 30 for samples in which only the nasopharyngeal target was detected. Red horizontal and vertical lines indicate the median. The median for each group was 5.27 log₁₀ copies/10,000 cells and 3.69 log₁₀ copies/mL for nasopharyngeal and saliva samples, respectively. NP, nasopharyngeal; SCPS, self-collected pure saliva.
