I don't have time or patience to explain thoroughly, but you have completely misunderstood the point of that article.  There is no evidence for a more transmissible strain.  "Mutation" here simply means that the virus' RNA changed over time.  Most such changes are meaningless for the lethality or infectiousness of the virus.

You should delete this.
