British officials could declare one of the new coronavirus strains first found in India a variant of concern", the BBC said on Friday, as scientists flagged evidence that it spreads more quickly than the original
version of the virus.
Scientists have recommended that one version of the variant first found in India, known as B.1.617.2, is designated a "variant of concern", the BBC said, adding more than 500 cases of the variant had been recorded, up from 202 last week.
Public Health England (PHE), which postponed publication of its weekly data on variants on Thursday, had no immediate comment on the report, according to Reuters.
Jeff Barrett, Director the Wellcome Sanger Institute COVID-19 Genomics Initiative, said that high numbers of cases of B.1.617.2 in Britain and around the world were "consistent with this one being more transmissible than older versions of the virus from last year".
"(It's) possibly as transmissible as the B.117 Kent variant that is very widespread in the UK," Barrett said on BBC radio, referring to the strain found in south-east England which fueled Britain's second COVID-19 wave.
The original India variant, B.1.617, was first detected in October, but Public Health England (PHE) has categorized three different subtypes, all with slightly different mutations.
Other variants of concern include variants first identified in Kent, south-east England, as well as South Africa and Brazil, and Barrett said that there had been reassuring evidence from real world studies on the effectiveness of vaccines on those.
"That paints a relatively positive picture that the vaccines are going to continue to have efficacy," he said.
"So obviously for new variants like this one, we need to do additional experiments and really get the solid proof one way or the other about that".
