Abstract

Highlights: Self-collected nasal and saliva samples can be used for SARS-CoV-2 screening. Self-collected nasal and saliva specimens had a 99% and 90% sensitivity, respectively. Nasopharyngeal swab viral loads correlate better with nasal than saliva. Viral load correlations are poorer at day 7, when lower viral loads are observed.
