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. [2] [3] These variants contribute to the continuation of the COVID-19 pandemic.
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 ]
The continued spread of the SARS-CoV-2 virus has spawned a Greek alphabet of variants - a naming system used by the World Health Organization to track concerning new mutations of the virus that ...
The mutation rate estimated from early cases of SARS-CoV-2 was of 6.54 × 10 −4 per site per year. [86] Coronaviruses in general have high genetic plasticity, [89] but SARS-CoV-2's viral evolution is slowed by the RNA proofreading capability of its replication machinery. [90]
The Beta variant, [1] [2] (B.1.351), [a] was [5] [6] a variant of SARS-CoV-2, the virus that causes COVID-19. One of several SARS-CoV-2 variants initially believed to be of particular importance , it was first detected in the Nelson Mandela Bay [ 7 ] metropolitan area of the Eastern Cape province of South Africa in October 2020, [ 8 ] which was ...
The European Centre for Disease Prevention and Control (ECDC) also list a fourth spike mutation of interest: [14] D614G. This is a substitution at position 614, an aspartic acid-to-glycine substitution. [15] Other variants which have the D614G mutation include the Beta and Delta variants, and the mutation is associated with increased ...
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 ]
