This must be the BA.2 variant of Omicron you're referring to.
Dr JC did a video about it the other day and admitted it's not believed to be any more serious than the original BA.1 variant so far.
The BBC site also covered it very briefly a few days ago in their live rolling Covid section, but it mostly appears to have been kept low-key and barely mentioned since.
A couple of weeks back there was talk of a couple of other 'new' variants; one that was allegedly reported in Cyprus dubbed 'Deltacron' (a kind of Delta-Omicron hybrid), but that was also largely believed to be some kind of lab mix-up, rather than a genuine infectious Covid variant, again according to Dr JC. But the BBC never seemed to mention it though.
The other one that I already mentioned at the time; IHU, that was detected in a handful of individuals in Marseilles, France, has also barely been mentioned since.
Also, what happened to that mysterious 'Delta Plus' variant that was discovered here in England during the latter half of October 2021?
