Relative coverage of SARS-CoV-2 genomic variants, which differentiate strains 1 and 2. Genomic positions are at the X-axis, their relative frequencies are at Y-axis. A Sample 1, sequencing using genome fragments amplification (SCV-2000 bp protocol); B Sample 1, sequencing using total RNA library; C Sample 2 (collected eight days later), sequencing using genome fragments amplification (SCV-2000 bp protocol)
