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.
Delta (B.617.2) First identified in India in late 2020, the delta variant soon spread across the globe. It became the dominant variant of SARS-CoV-2 until the emergence of omicron in December 2021.
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 ...
There were two new BA.2 subvariants detected in the US state of New York, which are BA.2.12 (or B.1.1.529.2.12) and BA.2.12.1 (or B.1.1.529.2.12.1), both of which have a significant growth advantage of 23–27% over BA.2 and contributing to a rise in infections in central New York, centred on Syracuse and Lake Ontario, which later became ...
What are the FLiRT variants, KP.2, KP.3, and KP.1.1? ... The FLiRT variants are just the latest in a long line of new variants that have surfaced from SARS-CoV-2. These strains are new to the ...
The FLiRT variants — KP.3, KP.2 and KP.1.1 — are spinoffs of JN.1.11.1, a direct descendant of JN.1, and were initially detected in wastewater samples from across the country. ... The SARS-CoV ...
Since genomic analyses showed significant genetic differences between the SARS‑CoV‑2 variant sampled on those two dates, the case study authors determined this was a reinfection. [78] The man's second infection was symptomatically more severe than the first infection, but the mechanisms that could account for this are not known. [78]
The Gamma variant (P.1) [a] was [6] [7] one of the variants of SARS-CoV-2, the virus that causes COVID-19. [8] This variant of SARS-CoV-2 has been named lineage P.1 and has 17 amino acid substitutions, ten of which in its spike protein, including these three designated to be of particular concern: N501Y, E484K and K417T.
