More than 400 cases of a new Omicron sub-variant, dubbed a 'variant under investigation', have been detected in England.
Health chiefs say 426 Omicron BA.2 infections have been confirmed by Whole Genome Sequencing, beginning with a case back on December 6.
Authorities have warned the new strain could spread faster than the original BA.1 Omicron strain, but are stressing that it is too early to be certain about that yet, The Mirror reports.
