Delta plus sub-variant, found in five states, could be more infectious than the original Delta

Scientists are keeping a close eye on the Delta offshoot, known as AY.4.2 , which has been spreading in the U.K. since July.

commissioner Scott Gottlieb has referred to AY.4.2 as 'Delta Plus'—a term which earlier this year was used to refer to a Delta variant with the K417N mutation. It's not clear whether the two are interchangeable.In any case, according to Outbreak.Info—which uses virus sequencing data from the GISAID database—the variant took off in the U.K. some time around early July and has since accounted for between seven and eight percent of new sequenced samples.

Some 14,705 cases with this new variant have been reported in the country overall. It is a lot less widespread in the U.S.AY.4.2 has been detected in five states: Washington, Oregon, California, North Carolina, and Washington, D.C., with seven cases reported overall. This

marks an increase of one case since Monday,according to Outbreak.Info.Scientists have begun to take note of AY.4.2. Francois Balloux, director of the Genetics Institute at University College London, tweeted over the weekend that the variant is possibly around 10 percent more transmissible than Delta based on its recent rise in the U.K. headtopics.com

To summarise, the recent rise in the UK of AY.4.2 would be compatible with a transmissibility advantage of ~10%. As such, it feels worthwhile keeping an eye on it. Though, based on its genetic make-up, it is not a priori an obvious VoC candidate.8/October 16, 2021

He added that"it feels worthwhile keeping an eye on it," though its characteristics at this stage do not necessarily mean it is a candidate for becoming a Variant of Concern."The emergence of yet another more transmissible strain would be suboptimal," Balloux told the Science Media Centre this week.

"Though, this is not a situation comparable to the emergence of Alpha and Delta that were far more transmissible—50 percent or more—than any strain in circulation at the time. Here we are dealing with a potential small increase in transmissibility that would not have a comparable impact on the pandemic."

Professor Christina Pagel is a mathematician at UCL who specialises in mathematical modelling for health purposes. She toldNewsweekthat the potential 10 percent transmissibility advantage of AY.4.2"isn't great," but added:"I don't think there's a reason to think AY.4.2 is disastrous." headtopics.com

She said its advantage is"not nearly" as badover Alpha that allowed it to dominate vast swathes of the planet. Read more: Newsweek »

Ugh how many more variants will there be? We'll never get rid of this virus This world is apparently our forever new normal It ain't over yet. The delightful outcome of vaccination. Delta Plus, now with more cleaning power. How about the lambaada varient? 😟

New Zealand reports record daily cases as Delta spreadsNew Zealand recorded on Tuesday the highest number of daily cases since the pandemic began last year, as the Delta variant of the coronavirus spreads in its biggest city Auckland. While in a nationwide pri, pardon, Lockdown?

Why COVID-19 booster shots weren't tweaked to better match Delta variantMore COVID-19 booster shots may be on the way — but when it’s your turn, you’ll get an extra dose of the original vaccine formulation, not one updated to better match the extra-contagious Delta variant. horrible Pharma want more money
