NPSOPS
Influenza A virus RNA gene copy concentration in oropharynx and nasopharynx samples. Paired nasal and throat swabs were pooled in viral transport medium immediately after collection and subsequently processed for quantitative reverse transcription PCR to detect and quantify influenza A virus. The concentration was quantified in gene copies per milliliter. M gene was used as the gene target for the PCR assay, as described in a referenced study (Chan et al., 2008).
