Response to Dominant SARS-CoV-2 Variants: COVID Antigen Variants
SRAS-CoV-2 variants BA.2.86
The ever-evolving landscape of the COVID-19 pandemic has introduced us to various SARS-CoV-2 variants, each with its unique genetic makeup and potential implications. In this article, we will delve into two prominent variants, BA.2.86 and EG.5, which have garnered significant attention from the global health community. We will also explore the efforts of Taj Pharmaceuticals in developing crucial resources to combat these variants effectively.
SARS-CoV-2 Variant: BA.2.86
The World Health Organization (WHO) recently designated a new variant as a ‘variant of interest’—BA.2.86. Although the number of confirmed cases worldwide is relatively low, with only two dozen reported cases, this variant is causing quite a stir due to its genetic complexity. BA.2.86 boasts more than 30 gene mutations, a stark contrast to the original Wuhan-Hu-1 strain, which had only a handful. This new variant has accumulated a staggering 58 mutations. As of the latest data released by the WHO, only four known sequences of BA.2.86 have been identified, and there is no known epidemiological link connecting them.
SARS-CoV-2 Variant: EG.5
In contrast to BA.2.86’s limited prevalence, EG.5 has become one of the most widely distributed variants globally. It has been reported in over 53 countries and is responsible for approximately 23.8% of all COVID-19 cases. EG.5 originated in Indonesia and has been elevated to the status of a ‘circulating variant of interest’ by the WHO.
To combat the spread of these and other SARS-CoV-2 variants, it is crucial to monitor their impact on transmissibility, disease severity, and vaccine and therapeutic effectiveness. The WHO has categorized various variants based on these parameters, with some showing increased transmissibility or immune evasiveness, potentially affecting the efficacy of vaccines and treatments.
Let’s take a closer look at some of the key variants that have dominated the global landscape:
| WHO Label | Pango Lineage | Earliest documented samples | Transmissibility | Immune Evasiveness | Vaccine Effectiveness |
|---|---|---|---|---|---|
| Alpha | B.1.1.7 | United Kingdom | + + + | — — | √ |
| Beta | B.1.351 | South Africa | + | + + + + | √ |
| Gamma | P.1 | Brazil | + + | + + | √ |
