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 ...
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.
The many thousands of SARS-CoV-2 variants are grouped into either clades or lineages. [111] [112] The WHO, in collaboration with partners, expert networks, national authorities, institutions and researchers, have established nomenclature systems for naming and tracking SARS-CoV-2 genetic lineages by GISAID, Nextstrain and Pango.
Antiviral medications were tried in people with severe disease. [1] As of March 2020 several medications were already approved for other uses or were already in advanced testing. [43] As of April 2020 trials were investigating whether existing medications could be used effectively against the body's immune reaction to SARS-CoV-2 infection.
The latest mutations of SARS-CoV-2 — specifically KP.1, KP.2, KP.3, and their sublineages — accounted for most infections in the United States as of the first week of August, according to ...
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 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 ]
