Public Health England has divided the Indian variant in three sub-types because they aren't identical. While the South Africa variant is known to have spread within the UK, evidence for this happening with the Indian strain is limitedDespite cases rising, the Indian variant doesn't make up anywhere near as many cases as the Kent variant (purple), which is dominant in Britain. Scientists are unsure exactly how transmissible or vaccine-resistant the Indian variant is because it hasn't been studied thoroughly. The UK currently classes the Indian strain as a 'Variant Under Investigation', a tier below the Kent, South African and Brazilian variants. The vast majority of Covid cases in Britain are still the Kent variant (96 per cent) and the Indian strain is confined to localised cases or clusters of infections.
