In the case of COVID-19, the virus has mutated multiple times, leading to variants like Alpha and Delta, and various subvariants of Omicron. ... Omicron constitutes the current strain of COVID-19 ...
SARS-CoV-2 is the virus that causes coronavirus disease 2019 (COVID-19). Some have been stated, to be of particular importance due to their potential for increased transmissibility, [ 1 ] increased virulence, or reduced effectiveness of vaccines against them.
Just like other COVID-19 strains that have gained dominance in the U.S. over the last year — JN.1, HV.1, EG.5 aka Eris, and XBB.1.16 or Arcturus — the FLiRT variants part of the omicron family.
This article aims at keeping an up-to-date list of Coronavirus strains and subspecies successfully isolated and cultured in laboratory, a task which is often challenging. When relevant it shall include a few synthetic chimera as well as some strains that were only propagated in laboratory animals.
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 ...
A group of closely related viruses is called a lineage and the direct descendants of each variant are referred to as a sublineages — for example, BA.2.75 is a sublineage of BA.2.
[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. SARS-CoV-2 is of zoonotic origin; its close genetic similarity to bat coronaviruses suggests it emerged from such a bat-borne virus . [ 18 ]
