After the cases of Delta Variant of Covid-19 continuously rising, a new variant called Lambda Variant (LV) is emerging as a new threat.

  • Lambda Variant is dominant in Peru; India has not yet reported any case of LV.


  • The strain was first identified in Peru in December 2020. Lambda is the dominant variant in the South American country with 81% samples found to be carrying it.
  • Until recently, it was largely concentrated in a handful of South American countries, including Ecuador and Argentina, but since April it has been detected in more than 25 Countries.
  • Previously known by its Formal Scientific Name C.37, the World Health Organisation (WHO) designated this variant seventh and the newest Variant of Interest (VOI).
    • Another four have been designated as ‘variants of concern’.
