Researchers in South Africa are racing to track the concerning rise of a new variant of the SARS-CoV-2 coronavirus that causes COVID-19. The variant harbours a large number of the mutations found in other variants, including Delta, and it seems to be spreading quickly across South Africa.
A top priority is to follow the variant more closely as it spreads: it was first identified in Botswana earlier this month and has since turned up in a traveller arriving in Hong Kong from South Africa. Scientists are also trying to understand the variant’s properties, such as whether it can evade immune responses triggered by vaccines and whether it causes more or less severe disease than other variants do.
“We’re flying at warp speed,” says Penny Moore, a virologist at the University of the Witwatersrand in Johannesburg, South Africa, whose lab is gauging the variant’s potential to dodge immunity from vaccines and previous infections. There are anecdotal reports of reinfections and of cases in vaccinated individuals, but “at this stage it’s too early to tell anything”, Moore adds.
“There’s a lot we don’t understand about this variant,” Richard Lessells, an infectious-diseases physician at the University of KwaZulu-Natal in Durban, South Africa, said at a press briefing organized by South Africa’s health department on 25 November. “The mutation profile gives us concern, but now we need to do the work to understand the significance of this variant and what it means for the response to the pandemic.”

Vaccine effectiveness
To understand the threat B.1.1.529 poses, researchers will be closely tracking its spread in South Africa and beyond. Researchers in South Africa mobilized efforts to quickly study the Beta variant, identified there in late 2020, and a similar effort is starting to study B.1.1.529.

Heavily mutated coronavirus variant puts scientists on alert
Commentary:
If this new variant turns out to be worse than Delta, like a number of scientists are saying is possible, there will be a return to massive lockdowns and restrictions on civil liberties. Especially if it affects the vaccinated like Delta did. So much for those vaccines. I appears they've done nothing to stop the new variant.
Funny isn't it, they've named it the "Nu B" variant - as in "Newby". Give us a break. We are not all stupid. It's the FLU!!!! And if you want to be specific - it's the CHINESE WUHAN FLU!!!
"Fear has a new name..." and Covid Virus is it's name.
I'm waiting for the CDC to announce the "Andromeda Strain of COVID virus" is so contagious you can get it by text messages. Fauci will urge people to wear quadruple masks, lock themselves in their homes for the immediate future and wrap their bodies in plastic wrap. Joe Biden swill appear in a hazmat suit to address the nation but is quickly rushed off stage as he apparently passed one of his rancorous farts while suited up fogging his visor and making it impossible to read his teleprompter.
Meanwhile, Joey Xi's bombastic remarks berating Trump for his handling of the Chinese Virus needs to eat crow.
Bai Dung has handled it much worse than any other president before him. especially since he was handed a vaccine before he took the oath of office, sufficient PPE supplies and respirators that were scarce at the beginning of 2020.
Surely a president with all the decisive failures he has provoked and presided over in the last 10 months does not deserve to be president.
