The newer 'delta plus' variant has been spotted 'on occasion,' but it's not yet a concern, health officials said. For one, he says, there is only one known strain of the novel coronavirus - the original one, SARS-CoV-2, first discovered in Wuhan.

In the U.S., the delta variant accounts for nearly all COVID-19 cases. Just as Americans start taking off their masks, the Omicron subvariant BA.2 is quickly spreading across the United States, making up nearly a quarter of new COVID-19 infections, health officials. The AY.4.2 is 'one to watch because we have to continuously keep an eye on how this virus is changing,' said Van Kerkhove. Experts say COVID-22 will be the deadliest variant yet, Delta, Gamma and Beta variants will combine to create a super strain of Coronavirus Staff Report Aug 4:52 PM According to an immunologist, there is a new strain of COVID called COVID-22 and itвЂ™s possibly even deadlier than the Delta variant. health agency is currently tracking 20 variations of the delta variant. 'Delta is dominant, but delta is evolving,' she said, adding that the more the virus circulates, the greater chances it has to mutate. The delta variant remains 'by far the most dominant variant in terms of global circulation' said Maria Van Kerkhove, the World Health Organization's technical lead on COVID-19, at a public session this week. These changes have also been seen in other versions of the virus since the pandemic started, but haven't gone very far, Francois Balloux, director of the Genetics Institute at University College London. An expert has claimed the вЂsuper Brazilian Covid strainвЂ™ is likely already inside the country, as Boris Johnson is urged to increase his 15 million mid-February vaccine target. The variant has two mutations in the spike protein, which helps the coronavirus invade the body's cells. officials said this variant makes up 6% of all analyzed COVID-19 cases in the country and is 'on an increasing trajectory.' to see if it might spread more easily or be more deadly than previous versions of the coronavirus.

Scientists are monitoring the delta-related variant - known as AY.4.2.
