SARS-CoV-2 detection in SSLs from patients with COVID-19. (a) Scatter plots of Ct values obtained using the N2 primer set from facial SSL samples versus days from symptom onset. A total of 33 specimens from 24 patients were used in the analysis. Plots connected by lines indicate the same patient. (b) Positivity rates for SARS-CoV-2 in SSL samples collected on days 1–5 and 6–10 from symptom onset. The numbers in the bars indicate the number of individuals. (c) Comparison of SARS-CoV-2 detection results of RT-PCR in paired saliva and SSL samples (n = 14). (d) Scatterplot of Ct values obtained with the N2 primer set from the SSL samples versus days from symptom onset (n = 14) of face (●) and body (△).
