The UK, Brazil, Japan and South Africa are not the football teams but the names of the variants of the coronavirus, whose cases have been found in India. A variant of the SARS-CoV-2 virus has one or more mutations that distinguish it from other SARS-CoV-2 virus variants. The reason behind the new wave of covid 19 in India also cannot be ruled out as a unique strain with 'double mutation'. The coronavirus is continuously mutating. Based on these mutations, it is being said that at least 240 strains are active in India, but there are only a few of them, which are important at the stage of transformation.
During the pandemic, three changes were observed based on the mutation of the virus, one that caused the virus to spread rapidly, two, due to which the disease appeared more severe and three, due to which the virus immune system i.e. vaccine-like. When the World Health Organization began naming coronavirus variants, they used the Greek alphabet — Alpha, Beta, Gamma, Delta, and so on — to make them easier to describe.
The variant of the corona that was detected in Wuhan, China in December 2019 was called the alpha strain. In scientific terms, it is known as B.1.1.1.7. Due to the spread of this virus, about 28 lakh deaths have occurred worldwide so far. The US and European countries had the highest number of deaths due to the epidemic. This variant had 23 mutations, according to scientists.
This variant was first discovered in South Africa in the year 2020. B.1.351 is the scientific name for the beta variant. E484K and N501Y, two of their mutations, have been deemed the most dangerous. This variant was 50% more infectious than the previous one. It's possible that it can infect people who have recovered from the coronavirus, according to experts.
The coronavirus gamma variant was discovered for the first time in Brazil. P.1 is the scientific name for the gamma variant. E484K and N501Y, two gamma variant strains, are considered extremely dangerous. The investigation discovered that after receiving the vaccine, this variant has only a minor impact.
The coronavirus delta variant was discovered for the first time in India. It was discovered in October of the previous year. B.1.617.2 is another name for it. It is thought to be the most contagious corona variant on the planet. It was reported that another variant with the E484K mutation of the same strain, which was originally found in Kent, was found in Gloucestershire and Bristol.
On July 3, the Delta variant accounted for 51.7 per cent of cases in the United States, according to the US Centers for Disease Control and Prevention. According to Public Health England, the delta variant was responsible for 99 per cent of all corona infections in the UK as of mid-June. The delta variant has been found in 100 countries, according to the World Health Organization.
Indian genome scientists have detected this variant of the corona, about which the government said that E484Q and L452R mutations were seen in samples collected from Maharashtra. At the same time, according to Dr. Jeremy Camille, a virologist at the University of Louisiana, the E484Q mutation is similar to the B.1.351 (South Africa) and the E484K mutation seen in the P.1 variant of Brazil.
They are primarily classified in three ways by the World Health Organization (WHO). 'Variant under Monitoring', 'Variants of Concern' and 'Variants of Interest'. The 'Variants of Concern' include Alpha, Beta, Gamma, Delta, and Omicron. At the same time, 'Variants of Interest' have been assigned to variants like Lambda and MU. A SARS-CoV-2 variant with genetic changes suspected to affect virus characteristics and some indication that it may pose a future risk is classified as a variant under monitoring.
This means that if the family tree of the virus is seen, then frequent mutations in it lead to a situation where the virus starts showing different effects, it is considered 'Variants of Concern'. The L452R mutation was also found in the double variant in India. This mutation was first found in the US, which was called the California variant. The reason for the new wave of viruses in India is that some experts believe that this could be a double variant.
These days, a new variant of the coronavirus, Omicron, is in the headlines. It has been discovered in several countries. The World Health Organization (WHO) named this variant Omicron on November 26. B.1.1.529 is its scientific name. This type of Corona, on the other hand, is said to be more contagious. This variant was discovered for the first time in South Africa this week. This virus has spread to neighbouring countries such as Botswana. It also affects people who have been fully vaccinated. The new variant is more transmissible, according to Dr. Naveet Vig, chairperson of the covid Task Force at AIIMS Delhi. That is to say, it spreads faster. It's more effective at combating immunity.
The threat of a new variant Omicron of coronavirus in India was going on for the last several days and now, while giving information on this, the Union Health Ministry has said on Thursday that the new variant of coronavirus Omicron has now reached India as well. The Health Ministry said that a new variant of the corona has been found in two people in India and both these cases have been found in Karnataka. At present both these cases are under investigation. Meanwhile, cases of earlier variants are also present in India, which is a matter of great concern at this time.
At present, there are many variants of Corona in India, which include Alpha, Beta, Gamma, Delta and now Omicron. These variants are quite different from each other.
1. At present in India, the alpha variant cases are 9 per cent.
2. The case for the beta variant is 0.44 per cent.
3. The case of the gamma variant is 0.04 per cent.
4. The cases of delta variant are 63 per cent.
5. The case for the AY1-AY.25 variant is 17 per cent.
6. The cases of the Kappa variant are 11 per cent.
7. 21 cases of Omicron variant have been reported.
Joint Secretary of the Ministry of Health, Luv Aggarwal told in the press conference that within the last 24 hours, 2 cases of Omicron have been registered in the country. On this, the Principal Secretary said that we are keeping our eyes on the people coming in contact with both the people. Currently, researchers are keeping an eye on Omicron, the new variant of covid.
