New Delhi. The infection of the delta variant of Kovid has now spread to many countries of the world. The B.1.617.2 variant of Kovid is called the delta variant and this strain is believed to be responsible for the second wave of infection in India, now countries like Britain, Australia and America have also become cautious about the delta variant Because the cases of infection in these countries have started increasing again.
In May, the World Health Organization described the delta variant as “worrying”, with the WHO saying that the variant is more contagious and can also hoax the human body’s immune response. Let’s know about this variant –
what is delta variant
The delta variant is a new strain of covid, derived from the B.1.617 series of corona virus. This virus was identified in India in early 2021, which later spread throughout the country. This strain makes people sick very fast and is also responsible for the second wave of corona.Why is the Delta variant dangerous?
Some important changes have been recorded in the spike protein of the delta variant of Kovid, due to which this variant becomes more infectious and dangerous. According to a study published in England, this strain is more invasive and due to this more people have become ill in a given time than the alpha variant.
how fast the delta variant spreads
According to the study, the delta variant is 60 percent more infectious than the alpha variant of the corona. The alpha variant was 50 percent more infectious than the original strain of the coronavirus, the original strain of Kovid that emerged in late 2019.
Why is this so dangerous?
Actually, the spike protein of the delta variant has changed itself in such a way, that is, there has been a mutation in it that the antibodies present in the person’s body also become ineffective, break down. As a result, the person becomes infected again, whereas this was not the case with the earlier variants of Kovid. The immune response of the person is also proving to be weak in front of the delta variant.
Is the vaccine effective against the delta variant?
It has been found in most of the studies that the vaccines are effective against the delta variant but less effective. According to a Public Health England study, a single vaccine from Pfizer and Oxford AstraZeneca is 33 percent effective in cases with symptoms of corona, which increases to 88 percent and 66 percent after the second dose.
In which countries has the Delta variant spread so far?
According to a report in Deccan Herald, the Delta variant has spread to more than 70 countries. This variant is found in abundance in India, UK and Singapore. Last week, the delta variant was found in 90 percent of new cases of corona in Britain. The number of new cases in Britain has seen a 65 percent increase since May.
