Even if A.30 was "more contagious", like Alpha, it isn't as contagious as Delta and thus would get outcompeted.
There's a lot of variants of concern. Its important to keep an eye on new variants, but don't worry about them until they cross the 1% or 5% mark. At that point, you can better theorize that they might be outcompeting the dominant strain.
You _really_ don't know that something is outcompeting until it reaches 50%. But by then its too late. The 1% or 5% points are still a month or two in advance of the 50% crossing, in both Alpha and Delta.
So that's where I keep my attention: at the 1% and 5% points. A variant gotta get to 1% before it can reach 50% of the world ya know?
