Six complete viral genome sequences, seven polyproteins (RdRp region) and seven glycoproteins available on NCBI portal on 4 Feb 2020 were taken for analysis. The sequence details and GenBank accession numbers are listed in Supplementary Table . Amongst the seven polyproteins, five are of Wuhan pneumonia virus isolate SARS-COV-2 and two sequences are of Wuhan pneumonia virus isolate SI200040-SP. The seven Glycoproteins are of the same isolate, Wuhan pneumonia virus isolate SARS-COV-2.
