There is also a Singapore study that has identified strains with large gene deletions, but I haven’t yet updated the post to include it [0].

I’m a lay person here, but it seems a foregone conclusion that viruses experience frequent mutation, and that a novel virus infecting a new host species for the first time is going to see a relative explosion in mutations due to the extreme increase in the number of opportunities for it to occur.
