Prospective Comparison of Saliva and Nasopharyngeal Swab Sampling for Mass Screening for COVID-19

23 Feb 2021

Abstract excerpt

Current testing for COVID-19 relies on reverse-transcriptase polymerase chain reaction from a nasopharyngeal swab specimen. Saliva samples have advantages regarding ease and painlessness of collection, which does not require trained staff and may allow self-sampling. We enrolled 776 persons at various field-testing sites and collected nasopharyngeal and pooled saliva samples. One hundred sixty two had a positive...
