Delta plus variant of COVID-19
Delta plus variant of COVID-19 or AY.1 variant has been confirmed by central government appeared from a mutation in the Delta variant of SARS-CoV-2 virus.
Why Delta plus is variant of Interest(Vol) –
The present status over the new variant is that yes, a new variant has been found. Delta plus is a variant of interest(VoI), nonetheless a variant of concern(VOC).
In the public domain, this variant resisting the use of monoclonal antibodies cocktail is currently prescribed as a cure.
A variant of concern is one in which we have understood that there are adverse consequences to humanity.Indeed it could be due to increased transmissibility or virulence. We do not know such type of information about the Delta plus variant.
Origin of Delta plus variant –
During the second wave, Delta variant- B.1.617.2 exhibited its effect. Its higher transmissibility played a major role in making the wave intense.
Along the same line, an additional mutation has been detected, which has also been submitted to the Global Date System.
The variant was observed in Europe in March and has been notified and brought into the public domain on June 13.
The sequences have been reportedly found in Europe, Asia, and America.
This is to be noted that Public Health England on June 11 said that 63 genomes of Delta ( B.1.671.2) with the new K417N mutation have been identified so far.
The mutation is in the spike protein of Sars-Cov-2 which helps the virus to enter and infect the human cells.
What is happening in India on the new Delta plus variant.
It has been also told that the Delta plus variant of COVID-19 is present in six genomes from India.
The Maharashtra government has sent a substantial number of samples from various districts for genome.
The sequencing is to be done to verify if any new mutation of SARS-CoV-2 has taken place.
Scientists said the blood plasma from many fully vaccinated individuals will have to be tested. Furthermore to determine whether it shows any significant immune escape.
