The Latest Covid Variant Is 1.5 Times More Contagious Than Omicron by Loveurneighbour: 3:57pm On Jan 29, 2022
The latest Covid variant is 1.5 times more contagious than omicron and already circulating in almost half of U.S. states

There are already dozens of cases across almost half of the U.S. of a new Covid subvariant that's even more contagious than the already highly transmissible omicron variant.

Nearly half of U.S. states have confirmed the presence of BA.2 with at least 127 known cases nationwide as of Friday, according to a global data base that tracks Covid variants. The Centers for Disease Control and Prevention, in a statement Friday, said although BA.2 has increased in proportion to the original omicron strain in some countries, it is currently circulating at a low level in the U.S.

The subvariant is 1.5 times more transmissible than the original omicron strain, referred to by scientists as BA.1, according to Statens Serum Institut, which conducts infectious disease surveillance for Denmark.

The new sublineage doesn't appear to further reduce the effectiveness of vaccines against symptomatic infection, according to the U.K. Health Security.

"Currently there is no evidence that the BA.2 lineage is more severe than the BA.1 lineage," CDC spokesperson Kristen Nordlund said.

BA.2 overtook the original omicron as the dominant variant in Denmark over the course of a few weeks, said Troels Lillebaek, the chairman of the Scandinavian nation's committee that conducts surveillance of Covid variants.

BA.1 and BA.2 have many differences in their mutations in the most important areas. In fact, the difference between BA.1 and BA.2 is greater than the difference between the original "wild strain" and the Alpha variant, which was the first major mutation to take root across the world.

The BA.2 variant has five unique mutations on a key part of the spike protein the virus uses to attach to human cells and invade them, Lillebaek told CNBC. Mutations on this part of the spike, known as the receptor binding domain, are often associated with higher transmissibility.

The U.K. Health Security Agency on Friday said BA.2 has a "substantial" growth advantage over the original omicron. The sister variant spread faster than the original omicron in all regions of England where there were enough cases to conduct an analysis, according to the agency.

However, a preliminary assessment found that BA.2 doesn't appear to reduce the effectiveness of vaccines any more than the original omicron. A booster dose was 70% effective at preventing symptomatic illness from BA.2 two weeks after receiving the shot, compared with 63% effectiveness for the original omicron strain.

The World Health Organization has not labeled BA.2 a variant of concern. However, WHO officials have repeatedly warned that new variants will arise as omicron spreads across the world at an unprecedented rate. Maria Van Kerkhove, the WHO's Covid-19 technical lead, warned on Tuesday that the next Covid will variant be more transmissible.

"The next variant of concern will be more fit, and what we mean by that is it will be more transmissible because it will have to overtake what is currently circulating," Van Kerkhove said. "The big question is whether or not future variants will be more or less severe."

Lillebaek said there is not enough data yet to determine whether BA.2 is able to reinfect people who caught the original omicron. However, prior infection would likely provide some crossover immunity to BA.2.

Pfizer and Moderna started clinical trials this week on omicron-specific shots amid growing concern that new variants will emerge as immunity induced by the original vaccines wanes.

New Covid cases are increasing in Denmark, with more than 50,000 new infections reported on Friday in a country of 5.8 million people, according to the country's health ministry. Lillebaek said it's safe to assume that BA.2 is driving the increase of new infections in Denmark right now.

New hospital admissions in Denmark rose by 12 for a total of 967 patients who are Covid positive. Lillebaek said this increase is likely within the limits of what the health system can manage. However, he noted that 80% of Danes are fully vaccinated and 60% have received booster shots.

"If you are in a community or living in a country where you have a low vaccination rate, then you will have for sure more admissions to hospital and more severe cases and then more going to ICU," he said.

In the U.S., about 67% of those eligible are fully vaccinated, according to data from the CDC.

More shots on the way...If you have received only two shots you are no different from those who haven't been shot at all...and while we are still contemplating the new sub-variant in the US, news is coming out from Wuhan, sounds familiar, that there is a new variant of COVID called neo-COV and from their research of the virus it only needs one mutation, just one mutation, for it to jump species from bats to humans and attack human cells. The WHO is not asking why Wuhan, the ground zero for COVID-19, still have research institutions doing gain-of-function research involving bat corona-viruses. Very soon some idiot with a PhD in molecular genetics or microbiology will engineer the one mutation required for neo-COV to jump species and unleash it on the world. The neo-COV is estimated to have a mortality rate of 35%, that means out of 10 persons infected at least 3 people could die from it. Some satanic big pharmaceutical companies will be working on creating the vaccine for this neo-COV so that by the time it is unleashed and it has decimated a good proportion of the global human population they will be able to enslave whole countries and take the world back to the feudal times.

So for those who like receiving shots, get ready for more shots...

who cares since WAY LESS people are dying from these latest variants?!?!?
