- The UK Well being Safety Company says it designated a sub-lineage of the Omicron variant of the coronavirus beneath investigation.
- Britain had recognized 53 sequences of the BA.2 sub-lineage as of 10 January.
- In Denmark, the BA.2 sub-lineage went from 20% of all Covid-19 circumstances within the final week of 2021 to 45% within the second week of 2022.
The UK Well being Safety Company on Friday stated it had designated a sub-lineage of the dominant and extremely transmissible Omicron coronavirus variant as a variant beneath investigation.
BA.2, which doesn’t have the particular mutation seen with Omicron that can be utilized as a proxy to simply distinguish it from Delta, is being investigated however has not been designated a variant of concern.
“It’s the nature of viruses to evolve and mutate, so it is to be anticipated that we’ll proceed to see new variants emerge,” Dr Meera Chand, incident director on the UKHSA, stated.
“Our continued genomic surveillance permits us to detect them and assess whether or not they’re vital.”
Britain had recognized 53 sequences of the BA.2 sub-lineage as of 10 January, with up to date figures as a consequence of be revealed in a while Friday.
In Denmark, BA.2 has grown quickly. It accounted for 20% of all Covid-19 circumstances within the final week of 2021, rising to 45% within the second week of 2022.
Anders Fomsgaard, researcher at Statens Serum Institut (SSI), stated he didn’t but have a very good rationalization for the fast progress of the sub-lineage, including he was puzzled, however not fearful.
“It could be that it’s extra immune to the immunity within the inhabitants, which permits it to contaminate extra. We have no idea but,” he advised broadcaster TV 2, including that there was a risk that individuals contaminated with the unique Omicron, referred to as BA.1, won’t be immune from then catching BA.2 quickly after.
“It’s a risk,” he stated. “In that case, we should be ready for it. After which, in reality, we’d see two peaks of this epidemic.”
Preliminary evaluation made by Denmark’s SSI confirmed no distinction in hospitalisations for BA.2 in comparison with BA.1.
