, QIAGEN, Germany). Reference-based mapping was performed to retrieve the sequence of the SARS-CoV-2.
Full-length genome sequences of SARS-CoV-2 were downloaded from the GISAID database17 (Supplementary Table I (available from http://www.ijmr.org.in/articles/2020/151/2/images/IndianJMedRes_2020_151_2_200_281471_sm5.pdf)). Multiple sequence alignment was performed using the MEGA software version 7.018 with retrieved sequences from two of the three positive cases and the available GISAID sequences. A phylogenetic tree was generated using the neighbour joining method and the Kimura-2-parameter as the nuc
