XBB, a recombinant of the BA.2.10.1.1 and BA.2.75.3.1.1.1 sublineages, [174] is an Omicron subvariant first detected in August 2022. [ 175 ] On 20 October 2022, the chief scientist of the World Health Organization (WHO), Soumya Swaminathan, warned that the XBB subvariant of Omicron may cause infections in some countries while the severity of ...
This variant of SARS-CoV-2 has been named lineage P.1 (although it is a descendant of B.1.1.28, the name B.1.1.28.1 [67] [127] is not permitted and thus the resultant name is P.1), and has 17 unique amino acid changes, 10 of which in its spike protein, including the three concerning mutations: N501Y, E484K and K417T.
A user with a full genome sequence of a sample of SARS-CoV-2 can use the tool to submit that sequence, which is then compared with other genome sequences, and assigned the most likely lineage (Pango lineage). [5] Single or multiple runs are possible, and the tool can return further information regarding the known history of the assigned lineage ...
On 26 November at an emergency meeting in Geneva, Switzerland WHO's Technical Advisory Group on SARS-CoV-2 Virus Evolution designated PANGO lineage B.1.1.529 a variant of concern (VOC) and gave it the designation Omicron (skipping Nu and Xi, the next letters in the Greek alphabet in keeping with its nomenclature protocol introduced for the Delta variant).
[2] On March 13, 2021, the Department of Health confirmed the mutations constituted a new variant, which was designated as lineage P.3. On the same day, it also confirmed its first case of lineage P.1 in the country. Although the lineages P.1 and P.3 stem from the same lineage B.1.1.28, the department said that the impact of lineage P.3 on ...
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 latest mutations of SARS-CoV-2 — specifically KP.1, KP.2, KP.3, ... in late 2021 and was the last variant to mutate enough to significantly escape immunity from the original strain and ...
The Eta variant is a variant of SARS-CoV-2, the virus that causes COVID-19.The Eta variant or lineage B.1.525, also called VUI-21FEB-03 (previously VUI-202102/03) by Public Health England (PHE) and formerly known as UK1188, 21D or 20A/S:484K, does not carry the same N501Y mutation found in Alpha, Beta and Gamma, but carries the same E484K-mutation as found in the Gamma, Zeta, and Beta variants ...
