“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.
