A new major strain of coronavirus appears to be more infectious than the original.

According to a new study published by the Los Angeles Times, researchers have identified a coronavirus virus that appears to be more contagious than others that spreads quickly in epidemics and is now a major strain worldwide.

In a study by the Los Alamos National Laboratory published last week on Biorexiv, a website researchers have used to share before conducting the study, they say, the stress that emerged in Europe in February went to the United States and The world has become a major strain since mid-March, the Los Angeles Times reported on Tuesday.

The LA Times reports that the study was published in an effort to accelerate collaboration with scientists working on vaccines or treatments for COVID-19. The authors of the report said they felt "an urgent need for early warning", so the treatments and vaccines that have been developed will be effective against the new effective stress.

Researchers say that the strain, identified in the report as D614G, affects spikes outside the coronovirus that allow it to enter human respiratory cells and may make people susceptible to a second infection.

The study noted that the strain was prevalent in Wuhan, China, where the virus first arrived, and in some countries previously, proving that it is more contagious than previous strains.

The report was based on computational analysis of more than 6,000 coronovirus sequences around the world. The Los Alamos team, working with scientists from Duke University and the University of Sheffield, England, identified 14 mutations in all.

Co-author Bette Korber, a computer biologist from Los Angeles, wrote on her Facebook, "The story is disturbing, as we see mutated forms of the virus emerging very quickly, and in the month of March it takes the form of an epidemic." Already happened." . Page "When viruses with this mutation enter a population, they quickly begin to handle local epidemics, making them more permeable."

The tension appeared in Italy, one of the European countries most affected by COVID-19, around the same time in late February, when the original tension appeared.

In the United States, Washington State was affected by the original strain in late February, but in mid-March, the mutated strain was predominant. New York was affected by the original strain in mid-March, but according to the study, the mutated strain became dominant within days.

But as the new strain spread more quickly, researchers said it was not necessarily more fatal to those infected.

"We cannot afford to be blinded to pass vaccines and antibodies to clinical trials," Krobar wrote. "Please encourage us to know that the global scientific community is in it, and we are collaborating with each other in a way I have never seen before ... in my 30 years as a scientist."

The coronavirus has mutated. That's what it means

According to a new study led by scientists at the Los Alamos National Laboratory, a new version of the new coronovirus appears to be more infectious than ground at the start of the COVID-19 pandemic.

The new variety, called D614G, appeared in Europe in February before appearing on the east coast of the United States. Reportedly, it has been a major strain worldwide since mid-March. This fact is causing anxiety, not only because of the infectiousness of the new strain, but also because some believe that the existence of secondary stress has made some patients vulnerable to a second infection after avoiding a different stressor. can go.

Because much of the current research was focused on previous strains, such research may not apply to this new strain, Los Alamos scientists have warned.

The 33-page report was published on Biorexiv and has not yet been reviewed.

"The Spike D614G mutation is of immediate concern; it began to spread in Europe in early February, and when it was introduced to new territories, it quickly became an effective form. In addition, we locally Present evidence of recombination between circulating strains, indicating. Multiple stress infections, "the study authors wrote. "These findings [sic] have important implications for SARS-CoV-2 transmission, pathogenesis, and immune interventions."

The D614G is increasing in frequency at an alarming rate, indicating a fitness advantage over the original Wuhan strain that allows for rapid spread, ”the study continued.

According to the Los Angeles Times, one of the lead authors, Bette Kurber, a Los Almos computer biologist, wrote on her Facebook page that the findings were "disturbing." Korr is known for his contributions to HIV vaccine research.

Korber wrote on his Facebook page, "The story is disturbing, because we see the mutated form of the virus emerging very rapidly, and it has taken the form of an epidemic in the month of March." "When viruses with this mutation enter a population, they quickly begin to handle local epidemics, making them more contagious."

Korber said it was "hard news", but the public should not be "discouraged".

"Our team at LANL were able to make this mutation and its effect on transmission only due to a large-scale global effort by clinical people and experimental groups in their local communities such as new virus sequences (SARS-CoV-2) Thea. As soon as possible, "said Korr.

The salon has contacted Korr for comment and will be updated upon hearing the response.

The report was based on a computational analysis of over 6,000 coronavirus viruses collected by a project called the Global Initiative to Share All Influenza Data. In total, researchers have identified 14 mutations so far. In particular, the mutation of the new variant D614G affects the spike protein of the virus which allows the virus to enter the human host.

As reported by CNN, it is possible that a vaccine for COVID-19 will not be produced, or that the creation may take more than 18 months. Case in point: After four decades and 32 million deaths, there is no HIV vaccine in the world. This is due in part to the nature of the virus.

Influenza can change from year to year so that a natural infection or vaccine from the previous year does not infect you the following year. During an HIV infection, "Paul Offit, a pediatrician and infectious disease specialist who co-invented the rotavirus vaccine, told CNN." , "Office tells CNN". [And] while he is mutating, he is also paralyzing his immune system. "

Does this mean we may have to wait decades for the COVID-19 vaccine? It is too early to know, but some experts warn that humanity should think about restructuring to be better prepared to prevent the spread of coronovirus.

"It is absolutely essential that all societies everywhere place themselves in a position where they can defend themselves against coronoviruses as a constant threat and carry out social and economic activities with the virus among us, "Dr. David said. Nabarro, a professor of global health at Imperial College London, told CNN.

Trump Tours Mask Factory opt for safety goggles

President of the United States of America, Donald Trump, on Tuesday during a visit to the Arizona mask manufacturing plant, refused to wear a protective face mask instead of wearing safety glasses. The signs from the Honeywell factory that made the N95 masks warned that the masks were needed, and the employees shown in photographs with the president wore them. The Center for Disease Control and Prevention has advised everyone to wear masks since the beginning of April to delay the spread of COVID-19. White House officials said the president and his entourage were not required to wear protective gear. Trump's decision led to the controversial choice of applying masks on Vice President Mike Pence's visit to the Mayo Clinic, where masks were also required for all visitors.

One of Coronovirus more great agricultural science experts

According to a new article published in a BioRxiv preprinted file last week, a new coronavirus virus appears to be more infectious than one that causes the initial spread of the outbreak.

Research led by a team at Los Alamos National Laboratory suggests that one of the 14 mutations identified so far is the strain called D614G, a difference in its spike protein, the part of the virus that infects human cells.

It is important to note that the document has not yet been peer reviewed and any conclusions should be taken with a salt rash. As scientists rush to share their findings on coronoviruses, many scholarly papers are discussed in the mainstream without review, something that according to science can distort the public's understanding. Experts.

Nevertheless, discovery is a sin.

"The D614G is increasing in frequency at an alarming rate, indicating a fitness advantage over the original Wuhan strain that allows for rapid spread," the study says.

The team analyzed 6,000 samples from around the world and found through computer analysis that one particular strain repeatedly dominates others, suggesting that it is more contagious, the LA Times reports.

"The story is disturbing, as we see the mutated form of the virus emerge very rapidly," wrote Bette Korber, the lead author and computer biologist of Los Angeles on Facebook, and became a major epidemic in the month of March. " By the LA Times.

If the virus can mutate quickly, scientists will have a harder time finding an effective vaccine.

"We can't afford to be blind to pass the vaccine and antibodies in our tests," Kober added in his post.

Not everyone agrees that new research indicates that stress can spread rapidly to particular facilities. Bill Hanze, Associate Professor at Harvard T.H. The Chan School of Public Health tweeted that "this version may be fortunate and was launched in locations outside Wuhan and has different approaches to social distances from the start."

In other words, the tension did not spread because it inherently had more infectious properties, but by pure coincidence.

"It's not about the virus, it's the environment and the opportunities for transmission," Haines said.

"It's definitely a complicated subject, and one we'll learn more about," Hainaz argued in a follow-up tweet. "But right now there are better ways of fighting the epidemic than worrying about different strains."
