Inside the B.1.1.7 Coronavirus Variant
ByJonathan CorumandCarl ZimmerJan. 18, 2021
At the heart of each coronavirus is its genome, a twisted strand of nearly 30,000 “letters” of RNA. These genetic instructions force infected human cells to assemble up to29 kinds of proteinsthat help the coronavirus multiply and spread.

As viruses replicate, small copying errors known asmutationsnaturally arise in their genomes. A lineage of coronaviruses will typically accumulate one or two random mutations each month.
Some mutations have no effect on the coronavirus proteins made by the infected cell. Other mutations might alter a protein’s shape by changing or deleting one of itsamino acids, the building blocks that link together to form the protein.
Through the process of natural selection, neutral or slightly beneficial mutations may be passed down from generation to generation, while harmful mutations are more likely to die out.
Mutations In the B.1.1.7 Lineage
A coronavirus variant first reported in Britain has17 recent mutationsthat change or delete amino acids in viral proteins.
The variant was namedVariant of Concern 202012/01byPublic Health England, and is part of theB.1.1.7 lineageof coronaviruses.

Notable mutations in the B.1.1.7 lineage are listed below. Six other mutations, not shown in the diagram above, do not change an amino acid.
Eight Spike Mutations
Researchers are most concerned about the eight B.1.1.7 mutations that change the shape of the coronavirus spike, which the virus uses to attach to cells and slip inside.
Each spike is a group of three intertwined proteins:
Building one of these spike proteins typically takes 1,273 amino acids, which can be written as letters:

These mutations alter the shape of the spike protein by changing how the amino acids fold together into a complex shape.
The SpikeN501YMutation
Scientists suspect that one mutation, called N501Y, is very important in making B.1.1.7 coronaviruses more contagious. The mutation’s name refers to the nature of its change: the 501st amino acid in the spike protein switched fromN(asparagine) toY(tyrosine).

In a typical coronavirus, the tip of the spike protein is like an ill-fitting puzzle piece. It can latch onto human cells, but the fit is so loose that the virus often falls away and fails to infect the cell.
The N501Y mutation seems to refine the shape of the puzzle piece, allowing a tighter fit and increasing the chance of a successful infection.

Researchers think the N501Y mutation has evolved independently in many different coronavirus lineages. In addition to the B.1.1.7 lineage, it has been identified in variants from Australia, Brazil, Denmark, Japan, the Netherlands, South Africa, Wales, Illinois, Louisiana, Ohio and Texas.
In addition to N501Y, the B.1.1.7 has 16 other mutations that might benefit the virus in other ways. It’s also possible that they might be neutral mutations, which have no effect one way or the other. They may simply be passed down from generation to generation like old baggage. Scientists are running experiments to find out which is the case for each mutation.

One mysterious mutation in the B.1.1.7 lineage deletes the 69th and 70th amino acids in the spike protein.

In another recurrent deletion region, a number of coronavirus lineages are missing either the 144th or 145th amino acid in the spike protein. The name of the mutation comes from the two tyrosines (Y) that are normally in those positions in the protein.
Like the H69–V70 deletion, Y144/145 occurs on the edge of the spike tip. It may also make it harder for antibodies to stick to the coronavirus.

When spike proteins are assembled on the surface of a coronavirus, they’re not yet ready to attach to a cell. A human enzyme must first cut apart a section of the spike stem. The P681H mutation may make it easier for the enzyme to reach the site where it needs to make its cut.
Like N501Y,  the P681H mutation has arisen in other coronavirus lineages besides B.1.1.7. But it’s rare for one lineage to carry both mutations.

ORF8 is a small protein whose functionremains mysterious. In one experiment, scientists deleted the protein and found that the coronavirus could still spread. That suggests that ORF8 is not essential to replication, but it might still give some competitive edge over mutants that have lost the protein.
ORF8 is typically only 121 amino acids long:

The B.1.1.7  lineage has now been detected inover 50 countries, including theUnited States. Britain has responded to the surge of B.1.1.7 withstringent lockdowns, and other countries have tried toprevent its spreadwithtravel restrictions.

B.1.1.7 has been detected in at least14 states, but the United States hasno national surveillance programfor determining the full extent of its spread.
How Did the Variant Evolve?
A number of researchers suspect that B.1.1.7 gained many of its mutations within a single person. People with weakened immune systems can remain infected with replicating coronaviruses for several months, allowing the virus to accumulate many extra mutations.
When these patients are treated withconvalescent plasma, which contains coronavirus antibodies, natural selection may favor viruses with mutations that let themescape the attack. Once the B.1.1.7 lineage evolved its battery of mutations, it may have been able to spread faster from person to person.
Other Mutations in Circulation
One of the first mutations that raised concerns among scientists is known asD614G. Itemerged in Chinaearly in the pandemic and may have helped the virusspread more easily. In many countries, the D614G lineage came to dominate the population of coronaviruses. B.1.1.7 descends from the D614G lineage.

And scientists the variant is likely more contagious than previous versions of the virus. So this information could come out in the next few weeks.” Yes, in comparison with the non-variant virus. And scientists all over the world are rushing to figure out how the virus mutated and how big a threat the new variant poses. https://ukhsa.blog.gov.uk/2021/02/05/what-do-we-know-about-the-new-covid-19-variants/ All viruses mutate over time. But scientists now have "high confidence" the mutation itself has made the virus more transmissible - though not more deadly. “We may never know exactly what happened here.” The basic truth: The more this virus spreads, the more chances there are for dangerous new variants to emerge. The UK’s prodigious output means that as the novel coronavirus keeps mutating, there is a very good chance that important new mutations are going to be detected in this country first. After all, “this new variant has emerged at a time of the year when there has traditionally been increased family and social mixing,” according to the , which estimated that the transmissibility of the new variant has increased by 70 percent compared to prior versions of the virus. But the combination of these changes in a single virus could be making the new variant more likely to spread. Peter Horby, chair of the (NERVTAG), said Wednesday that scientists were “confident” the new variant is “spreading faster than other virus variants.” Speaking at an emergency meeting of the UK Parliament Science and Technology Committee, Horby explained that the new variant has “some kind of biological advantage to make it spread faster.” Scientists still don’t have a complete picture as to why, he said, but that there were a few different scenarios they were investigating. Public Health England Managing Director Susan Hopkins said that the Covid-19 variants discovered in the UK and in South Africa are both “more transmissible.” There is no evidence as of now to suggest that the new variant is more deadly, according to Whitty and the WHO, though it is too early to tell. As case numbers remain high around the world, the virus will continue to naturally evolve and many more variants and mutations are likely to be identified in the coming months, both in the UK and in other countries. Scientists in the UK recently uploaded a preprint paper reporting a new strain of the novel coronavirus, dubbed B.1.1.7, that is 56% more contagious and genetically diverse from other known variants. “There is a hint is that [the variant] … has a higher propensity to infect children,” he told a press briefing organized by the Science Media Centre (SMC), though he cautioned that more data was needed. The UK variant could have already arrived here undetected “given the small fraction of US infections that have been sequenced,” the CDC .
Title: Understanding the U.K. Variant: What Researchers Have Learned

The B.1.1.7 variant, first identified in the United Kingdom, has become a significant concern for researchers due to its increased contagiousness and genetic diversity. This new variant is estimated to be 56% more transmissible than other known variants, making it a critical focus for scientists worldwide.

One of the concerning aspects of the B.1.1.7 variant is its potential impact on children. While more data is needed, there is some evidence to suggest that this variant may have a higher propensity to infect children. This development is particularly worrying, as children were previously considered to be at lower risk of contracting and transmitting the virus.

The increased transmissibility of the B.1.1.7 variant is attributed to a combination of mutations that may provide the virus with an advantage, making it more likely to spread. Scientists are still investigating the exact reasons behind this increased transmissibility, but they are confident that the new variant is spreading faster than other virus variants.

Despite the efforts to minimize the risk of transmission during holiday seasons, the delta variant has caused a significant increase in active cases, deaths, and hospitalizations in some countries. The combination of increased social mixing and the emergence of new variants could lead to a surge in infections.

It is essential to note that, as of now, there is no evidence to suggest that the new variant is more deadly than the original strain. However, the World Health Organization (WHO) cautions that it is too early to tell, and the situation continues to evolve.

As case numbers remain high around the world, scientists expect to identify many more variants and mutations in the coming months, both in the UK and in other countries. The emergence of the B.1.1.7 variant highlights the importance of continued genomic surveillance and research to better understand the virus and its potential impact on public health.

In conclusion, the B.1.1.7 variant is a significant concern due to its increased transmissibility and genetic diversity. While more research is needed to understand its potential impact fully, scientists urge the public not to be complacent and to continue practicing safety measures to minimize the risk of transmission. As new variants emerge, ongoing genomic surveillance and research will be crucial to staying ahead of the virus and mitigating its impact on public health.
Title: Understanding the U.K. Variant: What Researchers Have Learned

The B.1.1.7 variant, first identified in the United Kingdom, has become a significant concern for the global scientific community due to its increased transmissibility. Researchers have been working tirelessly to understand the implications of this new variant and its potential impact on public health.

Initial studies suggest that the U.K. variant is approximately 56% more contagious than previously known variants. This increased transmissibility is attributed to a combination of various mutations in the virus's genome, which may enhance its ability to infect human cells and evade the immune system. One of the notable mutations, called N501Y, is located in the virus's spike protein and is believed to play a crucial role in the variant's increased infectiousness.

Another concern surrounding the U.K. variant is its potential impact on children. Although data is still limited, there is some evidence to suggest that the new variant may have a higher propensity to infect children. This is a significant departure from previous strains, which predominantly affected older adults. However, researchers emphasize the need for more data to confirm these findings and to better understand the implications for children and their role in virus transmission.

The U.K. variant has already spread to several other countries, including the United States. The first reported case in the U.S. was identified in Colorado, and since then, additional cases have been confirmed across multiple states. The Centers for Disease Control and Prevention (CDC) has warned that the new variant could become the dominant strain in the U.S. by March 2021, further highlighting the urgency for continued research and monitoring.

Title: Understanding the U.K. Variant: What Researchers Have Learned

The B.1.1.7 variant, first identified in the United Kingdom, has become a significant focus for the global scientific community due to its increased contagiousness and genetic diversity. Researchers are working tirelessly to understand the implications of this new variant and its potential impact on public health.

Initial studies suggest that the U.K. variant is 56% more contagious than other known variants, making it more transmissible. This increased transmissibility is attributed to various factors, including a higher propensity to infect children. While there is no concrete evidence to suggest that the new variant is more deadly, its ability to spread more rapidly is a cause for concern.

One possible explanation for the increased transmissibility is that the U.K. variant has some kind of biological advantage that makes it spread faster. Scientists are still investigating the specific reasons behind this advantage, but they have identified a few different scenarios that could be contributing to its spread.

The U.K. variant has already arrived in the United States, and there is a strong possibility that important new mutations will be detected in the country first. This is because the new variant has emerged at a time of year when there has traditionally been increased family and social mixing, making it more likely to spread.

Public health officials are urging caution and vigilance, even in countries where case numbers are currently low. As the virus continues to evolve naturally, it is likely that many more variants and mutations will be identified in the coming months, both in the U.K. and in other countries.

In summary, the U.K. variant is a significant concern for public health officials due to its increased transmissibility. While there is no evidence to suggest that it is more deadly, its ability to spread more rapidly makes it a serious threat.

Title: What Researchers Have Learned About the UK Variant: The B.1.1.7 strain and Its Propensity for Increased Contagiousness

In recent weeks, the B.1.1.7 variant of SARS-CoV-2, the virus that causes COVID-19, has been making headlines around the world, particularly for its increased rate of transmission compared to earlier strains of the virus. This variant, first detected in the United Kingdom, has been shown to be 56% more contagious, raising concerns about its potential impact on public health.

According to a preprint paper published by UK researchers, the B.1.1.7 mutation carries several genetic changes that may contribute to its enhanced transmissibility. One of the primary ways the virus could spread more easily is through increased viral load - that is, a higher concentration of the virus in an infected individual's respiratory system. This increase could lead to greater amounts of the virus being released into the air when an infected person breathes, talks, or coughs, raising the likelihood of transmission.

Another factor is the propensity for the new variant to infect children, according to a statement made by an expert at a press briefing organized by the Science Media Centre (SMC). While this has not been conclusively proven, it represents a significant shift from the perception that children are less likely to be affected by the virus.

Researchers are also investigating whether the altered spike protein of the variant may bind more effectively to the ACE2 receptor in human cells, allowing it to invade cells more easily and potentially leading to higher rates of transmission. The altered spike protein is one of the genetic changes associated with B.1.1.7, and further studies are needed to determine the exact role it plays in the variant's enhanced transmission.

The emergence of B.1.1.7, which has coincided with an increase in family and social mixing during the holiday season, has caused particular concern. The Centers for Disease Control and Prevention (CDC) has indicated that the variant may have already arrived in the United States undetected, given the small fraction of infections that have been sequenced for genetic analysis. This indicates a significant challenge in monitoring the variant's spread and managing its impact on the ongoing pandemic.

As scientists continue to research the B.1.1.7 strain, it is essential for the public to remain vigilant, especially as restrictions are lifted in some countries and the delta variant becomes more prevalent worldwide. According to experts, the high number of cases globally indicates that the virus is continually evolving, with the potential for more variants and mutations to be identified in the coming months.

In the meantime, it is crucial for individuals to adhere to public health measures to minimize the risk of transmission. These include wearing masks, practicing physical distancing, washing hands regularly, and getting vaccinated when possible. The scientific community remains committed to understanding and addressing the evolving nature of the virus, as nations around the globe work toward the goal of regaining control over the pandemic.
