Is there a new strain of the novel coronavirus? If so, what are some implications you foresee?

I know that news reports can often misrepresent scientific findings, even unintentionally. Still, here’s the article I came across. You can probably search “mutant coronavirus” or “new strain” or something similar to find other articles as well.

That article says the new strain isn’t deadlier, but it does seem to be more contagious, and it’s unclear if people who had the original strain will have immunity to the new strain (again, at least according to the article linked above.)

What implications do you foresee as a result?
