Determination of virus shedding in nasal washes collected from six ferrets challenged with SA01 (betaCoV/Australia/SA01/2020) and VIC01 (betaCoV/Australia/VIC01/2020) SARS-CoV-2 isolates. Ferrets 1 and 2 were challenged with 1 × 103 TCID50 SARS-CoV-2 VIC01; ferrets 3 and 4 were challenged with 5 × 102 TCID50 SARS-CoV-2 SA01; ferret 5 and 6 were challenged with 6 × 105 TCID50 SARS-CoV-2 SA01. Nasal wash samples from SARS-CoV-2 VIC01 infected ferrets are annotated blue and SARS-CoV-2 SA01 infected ferrets are annotated red. SARS-CoV-2 RNA was detected in nasal wash samples from ferrets 1, 2, 5, and 6 on 3, 5, 7, and 9-days post-infection (dpi). The dotted line box represents the limit of detection (LOD) of the reverse transcription qPCR assay. Part of this figure contains published data found in Marsh et al. [25]. The asterisks represents the defined period for SARS-CoV-2 virus shedding used to define sample groupings.
