The UK Health Security Agency said the sub-lineage known as BA.2 shows a low number of cases in the country, with the original Omicron lineage BA.1 still dominant.
The UK health authorities on Friday said they will be conducting further analysis into a sub-lineage of the Omicron variant of COVID-19 after designating it a variant under investigation (VUI).
The UK Health Security Agency (UKHSA), which monitors data related to the pandemic, said the sub-lineage known as BA.2 shows a low number of cases in the country, with the original Omicron lineage BA.1 still dominant.
A VUI designation is the initial step of investigation before being designated a variant of concern (VOC), which the original Omicron BA.1 currently is.
“The Omicron variant sub-lineage known as BA.2 has been designated as a variant under investigation,” UKHSA said.
