A ‘double mutant’ got detected from some samples of Covid infections in India, and scientists are now gene sequencing this variant. Research findings reveal that this new virus might carry two mutations, and it could be more infectious, and perhaps the current vaccines may not tame them.
What is a “double mutant” variant?
Like all viruses, the coronavirus keeps changing in small ways as it passes from one person to another, and we call these changes mutations.
We have known that mainly these mutations wreck little harm or may cause severe disease or escape the influence of the vaccine or sometimes prove less significant.
Health officials in India say that, unlike other variants, India’s new “double variant” shown no indications of being deadly or more quickly transferrable. Still, more data needed to understand the actual potential traits of the “double mutant.”
Preliminary evidence suggests that this “double mutant” seems more contagious than the previous virus strains in the first wave and spread more quickly in India, mainly the likely culprit behind the massive surge in Maharashtra. So in the second wave, they are sure to play a dominant role in this tsunami of the viral surge, but the data is not clear as yet.
Usually, the information of the new virus variants comes out through genome sequencing of the latest samples. A consortium of ten national laboratories in India under the health ministry carries out this exercise: Genomic sequencing is a testing process to map the entire genetic code of an organism – here, the Coronavirus. The virus’s genetic code tells the basic personality and behavioral traits of the virus, which gives the researchers an idea of whether the mutations are insignificant or deadlier.
