The term variant of concern (VOC) for SARS-CoV-2, which causes COVID-19, is a category used for variants of the virus where mutations in their spike protein receptor binding domain (RBD) substantially increase binding affinity (e.g., N501Y) in RBD-hACE2 complex (genetic data), while also being linked to rapid spread in human populations ...
The SARS-CoV-2 Kappa variant is also known as lineage B.1.617.1 and was first detected in India in December 2020. [2] By the end of March 2021, the Kappa sub-variant accounted for more than half of the sequences being submitted from India. [3] On 1 April 2021, it was designated a Variant Under Investigation (VUI-21APR-01) by Public Health ...
Epsilon variant, also known as CAL.20C and referring to two PANGO lineages B.1.427 and B.1.429, is one of the variants of SARS-CoV-2, the virus that causes COVID-19. It was first detected in California, USA in July 2020. [1] As of March 2022, Epsilon is considered as a previously circulating variant of interest by the WHO.
False-colour transmission electron micrograph of a B.1.1.7 variant coronavirus. The variant's increased transmissibility is believed to be due to changes in the structure of the spike proteins, shown here in green. There are many thousands of variants of SARS-CoV-2, which can be grouped into the much larger clades. [142]
The continued spread of the SARS-CoV-2 virus has spawned a Greek alphabet of variants - a naming system used by the World Health Organization to track concerning new mutations of the virus that ...
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 ]
The Delta variant (B.1.617.2) was [3] [4] a variant of SARS-CoV-2, the virus that causes COVID-19. It was first detected in India on 5 October 2020. It was first detected in India on 5 October 2020. The Delta variant was named on 31 May 2021 and had spread to over 179 countries by 22 November 2021.
Theta variant, also known as lineage P.3, [a] is one of the variants of SARS-CoV-2, the virus that causes COVID-19. The variant was first identified in the Philippines on February 18, 2021, when two mutations of concern were detected in Central Visayas . [ 1 ]
