Term:Variant of SARS-CoV-2

Normative

Variants and synonyms

• SARS-CoV-2 variant

Definition

These SARS-CoV-2 variants are designated as variants of concern (VoC) if they are associated with select characteristics, such as increase in transmissibility or virulence, decrease in effectiveness of vaccines and/or therapeutics, or interference with diagnostic test targets.

Encyclopaedic information

Emerging data regarding the prevalence and clinical significance of SARS-CoV-2 variants, and the efficacy of monoclonal antibodies against variants, may inform the choice of specific anti-SARS-CoV-2 monoclonal antibody therapy in the future.

Examples

Member States should also strongly discourage all non-essential travel to and from areas with a high prevalence of SARS-CoV-2 variants of concern or interest and to and from areas with an unknown prevalence due to insufficient sequencing volume.

Research

Variants and synonyms

• SARS-CoV-2 variant

Definition/description

However, the SARS-CoV-2 variant is likely to share a similar mechanism of action where the recombinant SARS-CoV-2 spike protein downregulates ACE2 expression and thereby promotes lung injury, as seen in the SARS-CoV variant [19].

Examples

We analyzed 68 sequences of SARS-CoV-2 variants in GISAID and found 4 variants with mutations in RBD (one has N354D/D364Y, two have V367F, and one has F342L).

Examples

Omicron has been proven to reinfect those who have been infected with other variants of SARS-CoV-2.

The new variant is now said to be half as bad as Delta which makes it still 5x more deadly to the unvaccinated.

I'm not convinced that this new strain is any milder than previous strains, but even if so; be very sure that the next worse strain is just around the corner.
