New Delhi: Corona cases are decreasing continuously in the country, in the last 24 hours only 32,906 new corona cases came in the country. This is the lowest in the second wave. On the one hand, the cases of corona are decreasing, while on the other hand there is relief among the people due to rapid vaccination. But what is worrying in the midst of all this is the changing nature of the corona which the variants do.
What are variants?
Corona virus is a virus that changes its form. When it passes from one person to another, it changes its form many times. During this change, the virus either becomes more dangerous than before or becomes weaker than before. It can be understood in simple language that when the virus makes its photocopy inside the body, many times a photocopy becomes slightly different from the first one. This is called its new variant. The variants are divided into two categories, the first is the variant of interest and the second is the variant of concern. According to the information, according to the information, WHO has so far kept 12 variants in different categories.
What is Variant of Interest (VOI)
You will be surprised to know that Corona virus has changed its form more than 24 thousand times so far all over the world. But in most cases its effects were not that severe or were completely inactive. But when a variant shows a change in its structure and nature after mutation, it is considered as a distinct variant. Initially, any variant is kept in the category of variant of interest. Scientists do research on this, collect data and try to find out whether this variant of the virus is dangerous or not.
What is Variant of Concern (VOC)
According to WHO, Variant of Concern is such a type of virus that spreads very rapidly, increases mortality, effects of vaccine Gives less or fails the earlier medical arrangements against the disease. It is very important to keep an eye on this type of variant when it is changing its nature and structure.
Know the variants of the Variant of Concern category
It was first found in southern England in September 2020, then later in December Placed in the category of Variant of Concern in 2020. Scientists named it B.126.96.36.199. The victim of this variant can die after reaching the ICU, with the patient becoming seriously ill within 28 days. Initially it was considered dangerous but after rapid vaccination it came under control.
beta variant was first found in South Africa in May 2020. In December 2020, it was included in the category of variants of concern. According to Johns Hopkins University, it had the potential to re-infect people who had recovered from the corona. Along with this, there was also talk of some vaccines being less effective. This increases the viral load in the affected person. Scientists named it (B.1.351), (B.1.351.2), (B.1.351.3).
Gamma Variant was first found in Brazil in 2020. In January 2021, it was included in the category of variants of concern. It is a virus spreading even more rapidly than the earlier variants. Along with this, it also escapes from the body’s immunity.
Delta Variant found in India in December 2020, it has been included in the Variants of Concern category. The scientific name of this variant is B.1.617.2. This is considered to be the most effective and infectious variant ever. People affected by this variant have difficulty in hearing, gas disease is formed and blood clots start forming in the body.
This new variant DeltaPlus (AY.1) is made up of mutations in Delta (B.1.617.2), first detected in India. Apart from this, the mutation named K41N which was found in the beta variant in South Africa also gives its symptoms. Therefore it is more dangerous. Some virologists have feared that this variant is 35-60 percent more contagious than alpha.
In December 2020 there was delta in 1 district, in March 21 in 52 districts. Delta variant was found in 174 districts. There are VOC mills in 35 states in 174 districts. There has been an increase in VOCs from 10.31% in May 2021 to 51% in June 2021. The Delta linked variant will be treated as VOC only. 50 cases have been found in 12 days.
Know the variants of the Variant of Interest category
After the Delta Plus variant of the corona virus, the Kappa variant created an atmosphere of fear is. However, the government has treated the Kappa variant as a variant of interest rather than as a variant of concern like the Delta variant. But when asked about this virus in the Health Ministry’s PC, NITI Aayog member VK Paul clarified that Kappa is not a new variant. At present, the government is assuming that there are not many cases of kappa variants, but in the expected third wave of corona, different variants have increased the challenge.
The origin of this variant is believed to be in Peru, South America. The World Health Organization (WHO) has given information about the lambda variant in its weekly report. The lambda variant of the corona virus is emerging as a new threat. According to the Ministry of Health of Malaysia, so far it has spread to 30 countries including Britain. So far, six cases have been identified in the UK and all of them have traveled abroad. This variant first appeared in Peru.
In December 2020, its patients were seen in many countries simultaneously. It was included in the variant of interest category on March 2021.
It was first seen in the US in November 2020. After this, the WHO included it in the Variant of Interest category on March 2021.
