Variant of SARS-CoV-2
The Lambda variant , also known as lineage C.37 , is a variant of SARS-CoV-2 , the virus that causes COVID-19 .[ 1] It was first detected in Peru in August 2020.[ 2] On 14 June 2021, the World Health Organization (WHO) named it Lambda variant[ 1] and designated it as a variant of interest .[ 3] On 16 March 2022, the WHO has de-escalated the Lambda variant to "previously circulating variants of concern".[ 4] [ 5]
It has spread to at least 30 countries[ 6] around the world and is known to be more resistant to neutralizing antibodies compared to other strains.[ 7] [ 8] [ 9] There is evidence that suggests the Lambda variant is both more infectious and resistant to vaccines than the Alpha and/or Gamma variant .[ 10] [ 11]

Lambda has been associated with substantive rates of community transmission in multiple countries, with rising prevalence over time concurrent with increased COVID-19 incidence. The earliest sequenced samples were reported from Peru in August 2020.
