After double mutant, triple mutant variant of coronavirus poses fresh challenge in Covid-19 battle
New Delhi/IBNS: Amid three lakh cases and over 2,000 deaths in the last 24 hours in India, triple mutant coronavirus has emerged as a fresh challenge in the Covid-19 battle, media reports said.
The current coronavirus wave had been attributed to double mutant strain of coronavirus which was said to be more infectious. Now, the triple mutant, meaning three different Covid strains combining to form a new variant, has been found in parts of the country, said an NDTV report.
Cases in Maharashtra, Delhi and West Bengal are believed to have infections caused by triple mutant variants, said the report.
Madhukar Pai, professor of epidemiology at McGill University, told NDTV that the triple variant is a more transmissible variant.
The more the virus spreads, the more it replicates and the more it mutates, according to experts.
He said the vaccines have to be tweaked to deal with the new variants which requires genome sequencing on war-footing and understanding of the disease.
Triple mutants are not only causing fresh infection spikes in India but across the world.
Double mutants have more severe pathogenicity, say scientists, show increased transmission rate and affect children too, according to scientists.
