Comparison between log viral loads by nasopharyngeal PCR and saliva PCR.
VIRUS
A) Log viral loads in RDT positive (black dots) and negative (white dots) patients. Dotted lines: Mean log viral loads; Black line: Considered threshold for presence of cultivable virus (nasopharyngeal PCR); B) Bland-Altman analysis showing the difference between nasopharyngeal and saliva log viral loads; SD = Standard deviation.Viral loads (by saliva PCR) were not significantly higher in patients with high volume of saliva (median 1.3x10
