Concordance rates were 95.2% (95% CI, 83.8-99.4), 95.5% (95% CI, 77.2-99.9), 85.7% (95% CI, 42.1-99.6) in nasopharyngeal swab, saliva, and sputum samples, respectively. These results indicate that the nCoV-DK effectively detects SARS-CoV-2 in all types of the samples including saliva, while reducing time required for detection, labor, and risk of human error. Nasopharyngeal swab, sputum and saliva samples were collected from 9 patients who 69 were admitted to our hospital after a diagnosis of COVID-19. Saliva as a 187 non-invasive specimen for detection of SARS-CoV-2 Comparison of SARS-CoV-2 detection in nasopharyngeal swab and saliva Detection of noroviruses in fecal specimens by direct RT-PCR 195 without RNA purification	./cache/cord-311333-shvtfxog.txt	./txt/cord-311333-shvtfxog.txt
