Nucleotide variation in SARS-CoV-2 reads: (A) Average percentage of nucleotide variation at different genomic position observed for more than 50 per cent of the sample set, with respect to the SARS-CoV-2 Wuhan HU-1 strain (accession number: NC_045512) for the reads retrieved from the Italian tourists (n=8); (B) their contacts in India (n=7); and (C) the Indian national sampled at Iran (n=11). The dark orange colour depicts the average frequency of the reads that mapped to the sequences in study, whereas the light orange colour depicts the average frequency for the reference allele.
