In India too, the speed of corona virus infection is increasing day by day. In such a situation many questions related to mutation and strain are circulating in the minds of people.
More than 770 variants of Kovid-19 have been revealed in India. A new ‘double mutant’ variant has also emerged which does not match the previously cataloged variants. The E484Q and L452R mutations have come together as a new variant.
The concern is that both these variants make the virus more contagious. There is also a possibility that the vaccine may not have that much effect on it
New variants within the virus keep coming in and they can vary depending on geographical location. SARS-CoV-2, which causes Kovid-19 due to recent interactions with humans, may not have fully adapted to human host. For this reason, the virus is constantly developing towards high infectiousness, but it is not necessarily the disease-causing properties that are also increasing in it
Recent reports indicate that the virus has accumulated novel mutations and is showing patterns of genomic diversity that are seen in different parts of the world. To track how widespread the epidemic is, it is necessary to find out the distribution of mutations and their properties
However, there is nothing to worry about now as the variants will settle down soon. Nevertheless, we need to move forward on 3 Ts i.e. test, track and treat. People have to wear masks continuously, follow social distancing and wash hands frequently
In the language of the common man, ‘variant’, ‘mutant’ and ‘strain’ are considered the same, although technically they are different.
RNA viruses (such as the corona virus) show an error many times during their duplication, causing new viruses to form if they are identical but not mimic those of the original virus. Such changes in viral RNA are called mutations and the viruses that carry them are called variants. A variant may have one or several mutations
The three most common SARS-CoV-2 variants are: UK variant (B.1.1.7) which is 0.6 times more infectious than that of only one N501Y mutation. South African Variant (B.1.351) with N501Y as well as E484K mutation and third is Brazilian variant.
If the variant has different physical properties and different behavior from the original strain, then we call it the new strain.
