Delta variant of coronavirus continues to be the dominant lineage for fresh cases of Covid-19 across India, while the other Variants of Concern (VoC) are at a lower rate and declining, INSACOG said on Thursday.
The delta variant has spread to at least 90 countries and is 50% more transmissible than the alpha variant, the variant first identified in Kent, which is around 50% more transmissible than the original Covid-19 that caused the pandemic.
INSACOG, a consortium of government panels involved in the genome-sequencing of the coronavirus, has also said that there is no evidence of any new Delta sub-lineage that is of greater concern than Delta at present.
