Figure 3. Comparison of virus shedding, measured as relative viral RNA content, in respiratory specimens taken from patients infected with oseltamivir-susceptible and oseltamivir-resistant influenza viruses A (H1N1), respectively, during the 2007–08 influenza season in Norway. Viral RNA content is expressed as the reverse-transcription–PCR cycle number (Ct) during which the fluorescence threshold was exceeded.
