A new sub-variant of Omicron Covid is now spreading throughout the nation.
The sub-variant known as BA.2 - or ' Stealth' Omicron - was first identified in December 2021 and has since been identified in countries worldwide.
Experts are continuing to study the new version of Omicron with a World Health Organisation (WHO) report confirming that B.A.2 is different from earlier mutations due to its cellular spike protein structure, reports The Mirror.
