The UK Health Security Agency is investigating a new COVID-19 variant, reportedly a sub-lineage of the Omicron variant titled ‘BA.2′.
Cases are believed to be very low, with 53 sequences found in the UK until January 10. Half of the cases in Denmark are BA.2 with primary studies revealing that so far, it has not caused any changes in the number of hospitalisations compared to the previous Omicron variant. Further data collection and analysis is required to extract more conclusive reports but UKHSA incident director Dr Meera Chand has stated that this new variant was expected due to viruses’ nature to evolve and mutate.
Statens Serum Institut (SSI) researcher told Danish station TV 2 that the variant may be “more resistant to the immunity in the population, which allows it to infect more,” albeit going on to state that “[they] do not know yet.”
In light of the emergence of this variant, some are concerned that the BA.2 may be more transmissible than BA.1 as researchers await further results to confirm these concerns.
