Outcomes
SECONDARY
The primary outcomes were the detection rates of SARS-CoV-2 positive patients by PCR on saliva, PCR on NP swab, and RDTs on NP swab, as well as the diagnostic performance (sensitivity and specificity) of i) RDT against NP PCR, ii) saliva PCR against NP PCR, and iii) any test against the other two tests. The secondary outcomes were the viral load of SARS-CoV-2 measured by NP PCR according to RDT results, the viral load by NP PCR and saliva PCR, as well as the diagnostic performance of RDT according to duration and intensity of symptoms.
