The following table presents information and relative risk level [66] for currently and formerly circulating variants of concern (VOC). [d] The intervals assume a 95% confidence or credibility level, unless otherwise stated. Currently, all estimates are approximations due to the limited availability of data for studies.
Distinct from the PANGOLIN tool, Pango lineages are regularly, manually curated based on the current globally circulating diversity. A large phylogenetic tree is constructed from an alignment containing publicly available SARS-CoV-2 genomes, and sub-clusters of sequences in this tree are manually examined and cross-referenced against epidemiological information to designate new lineages; these ...
Pages in category "Variants of SARS-CoV-2" The following 19 pages are in this category, out of 19 total. This list may not reflect recent changes. ...
This category is used for variants that are unlikely to be causative of disease, typically supported by population frequency data or functional studies suggesting no deleterious impact. A “likely benign” classification implies more than 90% certainty that the variant is not causative for a disease. [1]
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 variant's increased transmissibility is believed to be due to changes in structure of the spike proteins, shown here in green. The Alpha variant (lineage B.1.1.7) was first detected in early December 2020 by analysing genome data with knowledge that the rates of infection in Kent were not falling despite national restrictions.

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 ]
On 7 May 2021, PHE changed their classification of lineage B.1.617.2 from a variant under investigation (VUI) to a variant of concern (VOC) based on an assessment of transmissibility being at least equivalent to B.1.1.7 (Alpha variant); [15] the UK's SAGE using May data estimated a "realistic" possibility of being 50% more transmissible.
