All viruses, including SARS-COV-2 – which cause Covid-19 – evolve over time. When the virus replicates, some of the attributes change at the time; This change is called “mutation”. Viruses with one or more new mutations are referred to as “variants” of the original virus.
At present, the Delta variant quickly appears to be the most dominant tension in the world. Some other variants of the novel Coronavirus who have left health experts are Delta Plus and Lambda variants.
Some Covid-19 variants are dominant:
Delta variant: Delta variant of the Coronavirus novel or tension B.1.617.2, which was first detected in India, is now the dominant strain of Covid-19 in various countries. Now it has become dominant in India, Singapore, England and the United States and has been detected in more than 70 countries so far. The WHO elevates the Delta variant of ‘interesting variants’ to ‘variants of concerns’ quotes “significantly increasing the transmission of” and “more and more countries report outbreaks related to this variant”.
Delta Plus variant: Delta Plus variant, known as AY.1 (B.1.617.2.1) and AY.2 (B.1.617.2.2), quickly emerged as the main cause of global concerns. These variants, which are mutations from delta tensions, are allegedly more deadly and have a greater transmission. One variant – AY.1 – has been declared a variant of worries by the Indian government.
Kappa variant: According to the World Health Organization, the Kappa variant, which is a strain of B.1.617.1 from SARS-COV-2, is the only Covid-19 variant of the other first identified in India. However, this is not a new variant. According to WHO, the Kappa variant was first identified in India in October 2020. This variant is listed as an interesting variant.
Lambda variant: Lambda variant or tension C.37, appointed an interesting variant by WHO on June 14, was first identified in Peru in December 2020. The Lambda variant brings a lot of mutations with alleged phenotypic implications, such as increasing. transmission or resistance to penetration antibodies. This Covid-19 variant has been detected in more than 30 countries.
Epsilon variant: Epsilon SARS-COV-2 variant, which was first detected in California in 2020, also known as Cal.20c. It has five variations defining, including mutations in the surge in L452R protein. It was declared a variant of concern by the prevention center and controlling of the United States (CDC) at first but now becoming an interesting variant. It has been detected in 34 countries regardless of the US but it is not believed to be common anywhere.
What is the difference between the variance of interest and variant that is a concern?
Interesting variants: Covid-19 variants with specific genetic markers that have been associated with changes in binding receptors, reducing neutralization of vaccination, reducing the efficacy of maintenance, potential diagnostic impacts, or increased transmission and virulence.
Variant Concerns: Variants that have evidence of increased transmission, increased inpatient or death, significant reduction in neutralization with previous vaccination / infection, reducing the efficacy of care, diagnostic detection failure.
Can vaccination protect us from the Covid-19 variant that appears and there?
When the virus is widely circulating in a population and causes many infections, the possibility of mutations increase. This means, the more opportunities for viruses will spread, the more replication and mutate. Therefore, vaccination is very important to prevent further mutations.
According to the WHO vaccine, Covid-19 which is currently in development or has been approved providing protection against the new virus variant. Because this vaccine raises a broad immune response involving various antibodies and cells, mutations cannot make vaccines completely ineffective.
