Figure 1C shows To our knowledge, a few studies compared viral load between nasopharyngeal and saliva samples. The viral loads were 5-times higher in saliva than in nasopharyngeal samples in one study (5) , whereas they were lower in saliva in two studies (6, 8) . Our results showed that the viral load was equivalent at earlier time points but lower in saliva than in nasopharyngeal samples at convalescent phase. Saliva is more sensitive for SARS-CoV-2 detectionin COVID-19 patients than nasopharyngeal swabs. Sensitivity of nasopharyngeal swabs and saliva for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)	./cache/cord-025980-85jbwmfv.txt	./txt/cord-025980-85jbwmfv.txt
