Lambda, also called C.37, first found in Peru and currently classified as a Variant of Interest, has been detected in the U.K.
On June 23, 2021, Public Health England (PHE) designated the Lambda variant as Variant Under Investigation. PHE has identified six cases of Lambda, and all are linked to overseas travel. Currently, the PHE has provided no indication that the variant causes severe illness or can evade vaccines. However, the Independent reported that a non-peer-reviewed study based on samples from Chile's healthcare workers highlights Lambda variant's increased transmissibility. Furthermore, the author's of the study suggest that the Lambda variant is more infectious than the Alpha (U.K.) or Gamma (Brazil) variants. PHE said it would carry out laboratory testing to understand the variant better.
As of July 6, 2021, WHO has marked four variants of concern, including Alpha, Beta, Gamma and Delta. Furthermore, the international health agency has identified seven variants of interest, including the Lambda variant.
