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.
Alpha (B.1.1.7) The first highly publicized variant of the SARS-CoV-2 virus was called alpha (B.1.1.7). The variant began circulating in Great Britain in late 2020.
A UK case-control study for 54,906 participants, testing positive for SARS-CoV-2 between 1 October 2020 and 29 January 2021 in the community setting (not including vulnerable persons from care centres and other public institutions), reported that patients infected with the Alpha variant (VOC 202012/1) had a hazard ratio for death within 28 days ...
After a fairly quiet spring, COVID-19 cases are on the rise again in the U.S. and SARS-COV-2, the virus that causes COVID-19, keeps churning out new variants. The latest is a trio, KP.2, KP.3, and ...
SARS‑CoV‑2 is a strain of the species Betacoronavirus pandemicum (SARSr-CoV), as is SARS-CoV-1, the virus that caused the 2002–2004 SARS outbreak. [ 2 ] [ 17 ] There are animal-borne coronavirus strains more closely related to SARS-CoV-2, the most closely known relative being the BANAL-52 bat coronavirus.
The latest mutations of SARS-CoV-2 — specifically KP.1, KP.2, ... and deaths in Nebraska after vaccination with the 2023-2024 vaccines that targeted the XBB.1.5 variant, ...
The team at PANGO behind manually curating the phylogenetic tree of SARS-CoV-2 noted the earliest sequence was from 7 December 2020. They proposed a new designation for the variant containing the mutations at the spike protein including G142D, L452R, E484Q, D614G, P681R among others and this variant went to be assigned PANGO lineage B.1.617 on ...
BA.2.86 was first reported by Denmark and Israel. [1] [11] On 18 August 2023, when only six cases had been reported from four countries (Denmark, Israel, the United Kingdom and the United States), the British healthcare authorities noted that its almost simultaneous appearance in several countries still operating detailed genomic surveillance indicated that it likely already was spreading more ...
