What States Have The New Covid Strain

How Will The Us Vaccine Rollout Be Impacted By The Uk Strain

The new strain of coronavirus is likely here in the United States: Physician

Our working assumption from all the scientists is that the vaccine response should be adequate for this virus, Vallance said in a briefing on December 20. Thus, the strain that has shut down southeast England will not cut off the inoculation effort that began on .

U.S. scientists at the Walter Reed Army Institute of Research are still studying the mutation, but Dr. Nelson Michael, director of the institutes Center for Infectious Diseases Research, agreed that the current vaccines will probably be effective against the new variant. It stands to reason that this mutation isnt a threat, but you never know. We still have to be diligent and continue to look, Michael told CNN.

However, microbiologists that spoke with NBC News shared concerns that the virus could eventually grow to become vaccine-resistant. Whilst it may not be actually resistant, it may not take so many changes after this for it to get there, said Ravindra Gupta, a professor of clinical microbiology at the University of Cambridge. Simon Clarke, an associate professor in cellular microbiology at the University of Reading, said the COVID vaccine could eventually become like the flu shot, requiring an updated version every year.

How Is It Different

The B.1.1.7 variant has several mutations that affect the spike protein. This protein is found on the surface of the virus. Its what the virus uses to bind to and enter a host cell in your body.

This variant transfers more quickly between individuals. Public health officials in the U.K. note that B.1.1.7 is about 50 percent more infectious than the original coronavirus.

Why exactly this is isnt known, but its possible that the mutations in the spike protein help B.1.1.7 to bind more tightly to a host cell. Data from laboratory experiments thats currently in preprint supports this idea.

Additionally, some research has found that B.1.1.7 samples are associated with a higher amount of virus . Increased amounts of virus in people who have contracted this variant could also make it easier to transmit to other individuals.

Faster transmission can have a big effect because when a virus transfers more quickly, more people can become sick. This can lead to more hospitalizations and deaths, placing a heavy burden on healthcare systems.

A report from scientists in the U.K. also suggests that people who contract B.1.1.7 potentially have an increased risk for death. However, additional research is needed to investigate this finding.

other countries, including the United States.

What Is The Delta Variant Of Covid

The Delta variant, also known by its scientific name as B.1.617.2, was a strain of the coronavirus first identified in October in Maharashtra, India.

The strain was first named the Delta variant by the World Health Organization after the global health agency implemented a naming system based on Greek letters this month.

Although it is just one out of many variants that are spreading around during the pandemic, World Health Organization officials have called it a variant of concern.

Gottlieb said in a previous media appearance that all the COVID-19 vaccines work against the Delta variant in differing degrees.

The mRNA vaccine seems to be highly effective, two doses of that vaccine against this variant. The viral vector vaccines from J&J and AstraZeneca also appear to be effective, about 60% effective. The mRNA vaccines are about 88% effective, Gottlieb said, referring to the Moderna and Pfizer/BioNTech vaccines.

Are Coronavirus Variations Common

In general, viruses are prone to picking up small genetic changes as they move through a host population. Viruses that encode their genome in RNA, such as SARS-CoV-2, HIV and influenza, tend to pick up mutations quickly as they are copied inside their hosts, because enzymes that copy RNA are prone to making errors, Nature writer Ewen Callaway explains.

Scientists have been tracking minor changes in the COVID-19 genetic code since the beginning of the pandemic, and at least 1,000 variants have been detected so far. But the change to the spike protein found in southeast England represents one of the first coronavirus mutations that have made it more infectious.

As the Wall Street Journalnotes, this isnt the first time that COVID mutations have resulted in a more transmissible strain of the virus:

Scientists in July described a variant that over time displaced an older strain of coronavirus to become the dominant strain in the global pandemic. Experiments showed that variant, known as G614, replicated more quickly, but appeared to be just as susceptible to antibodies that target the earlier strain and wasnt associated with more severe illness.

The Delta Variant Is Now The Dominant Covid Strain In The Us

Mutant COVID

The highly transmissible delta variant is now the dominant strain of the coronavirus in the United States, the Centers for Disease Control and Prevention reported Tuesday.

As of July 3, the latest date for which data was available, the delta variant accounted for 51.7 percent of new Covid-19 cases that had been genetically sequenced in the country. Two weeks earlier, on June 19, the variant accounted for just over 30 percent of new cases.

Full coverage of the coronavirus outbreak

During a news briefing Tuesday, President Joe Biden cited the delta variant’s rapid spread to urge people to get vaccinated, “especially young people who may have thought that they didn’t have to be vaccinated, didn’t have to worry about it, didn’t have to do anything about it.”

“This should cause everybody to think twice,” Biden said.

Studies have shown that the Covid-19 vaccines are effective against multiple variants, including the delta variant. A recent report from Public Health England, where the variant accounts for more than 90 percent of new cases, found two doses of the Pfizer vaccine to be 96 percent effective against hospitalization.

In addition to the U.S., the delta variant has been detected in 103 countries and is predicted to become the dominant variant globally.

Is The Mu Variant More Transmissible

There are currently very few studies looking into the Mu variant. As research on this specific variant is all in early stages, its too early to know whether the strain is more transmissible or more severe than other variants.

One pre-print study which is yet to be peer-reviewed says that although the Mu strain is not yet classified as a variant of concern by WHO , the mutations found in the B.1.621 strain could have a synergistic impact on attributes such as reduction of vaccine-induced protection from severe disease, increased transmission and disease severity.

All viruses including SARS-CoV-2, the virus that causes COVID-19 evolve over time. When a virus replicates or makes copies of itself, it sometimes changes a little bit, which is normal for a virus. These changes are called mutations. A virus with one or more new mutations is referred to as a variant of the original virus.

Beta: The B1351 Lineage

A variant known as 20H/501Y.V2, from the B.1.351 lineage of coronaviruses, was first identified in South Africa in December. The World Health Organization named it Beta.

Scientists are concerned about the variant because clinical trials of vaccines are showing that they offer less protection against B.1.351 than other variants. People who recover from other variants may not be able to fend off B.1.351 because their antibodies wont grab the viruses tightly. The F.D.A. is preparing a plan for updating vaccines if the variant surges in the United States.

Why You Should Worry About The Mu Variant

New coronavirus strain in UK: How worried should we be? | DW News

Health officials still dont know much about the Mu variant, but early research has health officials scrambling to learn more.

The Mu variant is found to have key mutations linked to greater transmissibility and the potential to evade antibodies. More studies are needed to determine whether Mu variant is more contagious, more deadly or more resistant to vaccine and treatments than other COVID-19 strains, the Los Angeles County Department of Public Health said in a bulletin.

Vaccines remain the recommended method of protecting yourself against possiblie infection.

In About A Month The Uk Variant Is Likely To Become The Dominant Strain In The Us

On CBS’s Face the Nation on Jan. 17, former Food and Drug Administration commissioner Scott Gottlieb, MD, said that while it seems like these are small numbers, it’s only getting worse and it’s growing quickly. “Right now, this new variant is about 0.5 percent of all infections nationally. There’s hotspots in Southern California and Florida that may be closer to 1 percent, but it’s going to double every week,” Gottlieb said. “That’s the experience from other countries and that’s the experience we’ve seen so far in the United States. So it’s 1 percent now. It’ll be 2 percent, then 4 percent, then 8 percent, then 16 percent, then 32 percent. So in about five weeks, this is going to start to take over.” And for more on how you can protect yourself, you should Stop Doing This Immediately to Avoid the New COVID Strain, Doctors Warn.

Another New Strain Has Been Found In California

As the virus rages through southern California, authorities have identified another new strain in a dozen counties, and have connected it to several considerable outbreaks in Santa Clara County. The Los Angeles Timesreports that the California Department of Public Health is unsure if the variant is highly contagious or is just being identified frequently as lab work becomes more sophisticated. Similar to the U.K. variant, the one found in California appears to feature a mutation on the spike protein.

New Variants Of Coronavirus: What You Should Know

    In December 2020, news media reported a new variant of the coronavirus that causes COVID-19, and since then, other variants have been identified and are under investigation. The new variants raise questions: Are people more at risk for getting sick? Will the COVID-19 vaccines still work? Are there new or different things you should do now to keep your family safe?

    Stuart Ray, M.D., vice chair of medicine for data integrity and analytics, and;Robert Bollinger, M.D., M.P.H., Raj and Kamla Gupta professor of infectious diseases, are experts in SARS-CoV-2, the virus that causes COVID-19. They;talk about what is known about these new variants, and answer questions and concerns you may have.

    Why Does The Coronavirus Change

    This State Has the Biggest Outbreak of the New COVID Strain

    Variants of viruses occur when there is a change or mutation to the viruss genes. Ray says it is the nature of RNA viruses such as the coronavirus to evolve and change gradually. Geographic separation tends to result in genetically distinct variants, he says.

    Mutations in viruses including the coronavirus causing the COVID-19 pandemic are neither new nor unexpected. Bollinger explains: All RNA viruses mutate over time, some more than others. For example, flu viruses change often, which is why doctors recommend that you get a new flu vaccine every year.”

    Gamma: The P1 Lineage

    A variant known as 20J/501Y.V3 is from the P.1 lineage, an offshoot of the larger B.1.1.28 lineage.

    The variant was first reported in Japan, in four people who contracted P.1 on a trip to Brazil. The lineage, also known as Gamma, emerged in late 2020 in Manaus, the largest city in Brazils Amazon region. It quickly became the predominant variant there and in several other South American cities.

    P.1 is a close relative of the B.1.351 lineage, and it has some of the same mutations on the coronavirus spike protein. It may be able to overcome the immunity developed after infection by other variants.

    Iota: The B1526 Lineage

    A group of coronaviruses known as B.1.526 or Iota has been spreading rapidly in New York City. The variant appears in two forms: one with the E484K spike mutation, which may help the virus evade antibodies, and one with the S477N mutation, which may help the virus bind more tightly to human cells.


    The variant first appeared in samples taken in November, and by mid-February it accounted for about 27 percent of New York City sequences.


    spike mutation


    The mutation was noticed in New Mexico and Louisiana in late 2020. It seems to be scattered across the United States, but the country does not perform enough genetic sequencing to determine the full spread.

    Some of the seven lineages have spread abroad, and the Q677 mutation has also arisen independently in other countries.

    The Claim: Spike Protein Of Covid

    In recent weeks, many states began relaxing coronavirus restrictions as COVID-19 cases dropped and vaccination;rates crept toward President Joe Biden’s target of partially vaccinating 70% of American adults by July 4.

    The U.S. is expected to fall short of that goal, and now the nation faces another;setback: the spread of the contagious Delta variant. It now accounts for at least 20% of COVID-19 cases and is on the rise.;

    Variants aren’t unexpected. Whenever;a virus replicates inside its host, random genetic errors resulting in slightly altered versions of the original ;are a common occurrence. Since the start of the pandemic, there have been thousands of coronavirus mutations.;Some strains, like the Delta variant, are more contagious than others.

    But some on social media are claiming cases from;the new strain aren’t due to the virus but shedding from COVID-19 vaccines.

    “The new ‘vARiAnT’ is nothing more than the VX spike pr0teins inf*cting those vxd and unvxd,” ;claims a tweet shared in . Both Twitter and Instagram accounts are owned by the same user, who USA TODAY has reached;out to;for comment.;

    The tweet perpetuates a widely circulating, but grossly incorrect theory that the spike protein generated by the COVID-19 vaccines;can somehow cause disease or be shed and affect surrounding unvaccinated individuals.

    Neither is possible. The COVID-19 vaccines simply help the body develop immunity against the virus, including against the Delta variant.;;

    Vaccine Spike Proteins Cannot Cause Disease On Their Own

    India Reports Cases Of New Coronavirus Strain, 6 UK Returnees Test Positive for Mutant

    Vaccine shedding can occur;in rare cases;with some types of vaccines, but not with the ones currently available for COVID-19.

    “As none of the current COVID-19 vaccines authorized for emergency use in the USA contain live SARS-CoV-2 virus, viral shedding is not an issue for these vaccines,” Dr. Matthew Laurens, an infectious disease specialist and vaccine researcher at the University of Maryland School of Medicine, previously told USA TODAY.

    The vaccines authorized in the U.S. contain instructions for the spike protein either in the form of;messenger RNA or via a weakened cold virus stripped;of its ability to replicate.

    Regardless of the delivery system, the spike protein cannot cause disease on its own.

    When a coronavirus enters your body, usually through breathing in virus-laden droplets from other infected people,;the infection unfolds like this: The virus binds to a protein on the host cell surface, enters;the host cell, replicates, destroys the host cell as new viral particles are made and;dumped into the bloodstream.;

    Fact check:Coronavirus variants come from mutations, not vaccines

    A vaccine’s spike protein can’t do any of this since it’s genetically engineered to only enhance an immune response, is extremely localized once injected and lacks the genetic code to assemble a fully-formed viral particle. Once antibodies against it are made, the spike protein is mostly broken down by the host cell.;

    Delta Variant In Us: Which States Are Most At Risk As Covid Strain Spreads

    The most vulnerable areas of the country to Delta variant outbreaks have low vaccination rates and low rates of immunity from previous infections. AP

    The highly concerning Delta variant of COVID-19 is on the rise in the U.S., giving experts caution as the strain of the virus is spreading through certain parts of the country.

    Dr. Scott Gottlieb, the former head of the Food and Drug Administration, said Sunday on CBSs Face the Nation that there are certain parts of the country where we can have very dense outbreaks of the Delta variant.

    The most vulnerable areas of the country to these outbreaks have low vaccination rates and low rates of immunity from previous infections.

    According to a chart from the Centers for Disease Control and Prevention , the southern half of the U.S. has vaccination rates that fall well below the national average.

    The CDC said 46.1% of the U.S. has been vaccinated against the coronavirus.
