His results came positive following which he was asked to isolate and his sample was sent for sequencing. The BBMP further added that in a second test on November 23 conducted at a private lab, showed negative reports which he used to check out of the hotel on and fly to Dubai.

These 26-32 deletions of amino acids in the spike protein increase the SARS-CoV-2 virus' affinity to enter the human body. As it is a recent discovery, the transmissibility of the virus as well as its impact on vaccines is still to be studied.
