  • There was high correlation in the SARS-CoV-2 viral load measurements from paired self-collected pure saliva (SCPS) and nasopharyngeal swabs (NPS) from asymptomatic and mildly symptomatic patients with confirmed COVID-19 (r=0.72; n=31). SCPS performance was more similar to NPS among samples obtained from symptomatic adults, with 74% of samples in agreement.
