Early indications from an analysis of the growth of the B.1.617 variant of the Covid-19 virus has shown it to be at least twice as infectious as the UK variant and thrice as infectious as the variant behind last year’s Covid-19 wave.
Scientists involved in the whole genome sequencing as part of the Centre’s Covid-19 genomic surveillance exercise told The New Indian Express that this conclusion is based on the growth of this mutant, as compared to others, in districts where B.1.617 has been identified along with other variants in samples collected from infected individuals.
“We have been examining this data carefully and the way this lineage of virus, also called the double mutant, is growing as compared to others is remarkable,” said a senior scientist involved in the INSACOG project, a consortium of several institutions under the National Centre for Disease Control that carry out an extensive genomic surveillance. “For the public, what needs to be communicated very clearly is that there is a greater need to double mask and maintain social distancing as this virus is highly infectious.
** Update ** Tom Wenseleers: “Based on this data, the new variant from India has a very big transmission or growth advantage,” even over B.1.1.7, he says. “It’s kind of like the U.K. variant squared.”
