Comparison of viral loads according to RDT result, and duration and intensity of symptoms
Viral loads (by NP PCR) were significantly higher in patients with RDT positive (median 1.9x10Log viral loads by NP PCR and saliva PCR according to A) RDT result and B) intensity band of positive RDT.The sensitivity of RDT according to symptoms duration varied between 80% and 90%. It was lowest the day of symptoms onset (80%, 95%CI 44.4–97.5%) and highest on day 4 (90.0%, 73.5–97.9%) (Log viral loads according to symptoms duration by nasopharyngeal PCR (A) and sensitivity of antigen RDT (B).Viral loads (by NP PCR) were significantly higher (median 1.3x10
