Ct values by specimen type, severity and time since onset. Distribution of PCR cycle threshold (Ct) values by time from symptom onset to PCR specimen collection. Panels a and b represent Ct values of nasal and saliva (respective) specimens collected before or without receipt of antiviral treatment (remdesivir, casirivimab/imdevimab, bamlanivimab/etesevimab). Panels c and d represent Ct values of nasal and saliva (respective) specimens collected after receipt of antiviral treatment (includes receipt of remdesivir, casirivimab/imdevimab, bamlanivimab/etesevimab).
