So why is BA.2 a variant of Omicron rather than a whole new variant? Does it have to do with the genetic structure and how different it is, like genus/species?
Good question. No idea. Omicron is almost an entirely different animal. Seems to infect different areas of the body, spread indescribably fast, and not be that bad for most.
What I find interesting is that BA.1 and BA.2 were discovered within a week of each other, BA.2 actually before BA.1, and somehow BA.1 outcompeted it until now. Something has to have given BA.1 an edge until now. And if BA.2 is as infectious as described, it should have outcompeted. So the whole thing is kinda baffling to me. And more interestingly, BA.1.1 was dominant before BA.2.
So all of this makes me wonder if the latent period is longer for BA.2 than BA.1 (which was significantly shorter than even Delta and thus made it actually somewhat easier to spread initially but also made it more susceptible to rapid interventions). So that might be why BA.2 is outcompeting now. It might be more infectious but spread slower. I don't know. Just sh--itposting. I'm sure someone will figure it out.
