Fact check: The theory that SARS-CoV-2 is becoming milder

There is a growing story that is being reported in mainstream news media as well as on social media platforms, perhaps even at the dinner table. This means that the SARS-CoV-2 coronavirus is weakening, and changing into a less dangerous virus. In the near future, every new variant that is discovered is likely to cause less severe disease as compared to the earlier variant.

“There is a story that we are going to have variants that are progressively less severe,” Dr. Roby Bhattacharyya, an infectious disease specialist at Massachusetts General Hospital and Harvard Medical School.

It’s a lie Bhattacharyya claims. “It’s comforting to think that SARS-CoV-2 might have some tendency to evolve into a milder form. That’s not what we’re seeing here.”

This report has been circulated for the past month by doctors and researchers who have found evidence that the omicron coronavirus variant could cause less severe disease than the earlier variants.

According to data from South Africa, the UK, and the USA, Omicron patients are approximately 50% less likely to be admitted than those who are Delta. The chance of being placed on a ventilator if you are admitted to an institution is 75 percent lower.

Laboratory tests and animal studies have also shown that Omicron has a different effect on the lungs than previous versions. Biologists from the University of Cambridge discovered that Omicron doesn’t affect the lung cells in the same way as delta.

Ravi Gupta, along with his team, was particularly interested in understanding how delta and micron might affect lung and respiratory organoids. These are small clusters of 3D cells that look like certain types of tissue within the respiratory tract or lungs. lungs. Omicron developed 10 times slower than delta inside the lung cells. Researchers did not observe any differences in the replication of lung cells in the upper airways.

Gupta says that “omicron growth was severely impaired in cells that had been infected very aggressively with delta.” “And that was a shock because we were seeing Omicron spread very rapidly around the globe, but the [ability] to grow it in certain cell types was actually attenuated.”

The study also showed that omicron enters cells in a completely different way than delta. This is believed to be less harmful to the lungs. Gupta says that these differences are having dramatic clinical consequences. Patients have less inflammation and require less oxygen.

Gupta and his colleagues published their findings last month online. Gupta says that the media “seized upon them as a sign of the end of COVID” after their publication. “I was very worried about that narrative because…omicron is still a very dangerous infection.”

SARS-CoV-2 does not appear to be changing to a milder version of omicron.

Gupta says, “It is important to emphasize that the next variant, which there will be one, may evolve from omicron, and won’t necessarily possess these features.” Gupta. Gupta.

The story of SARS CoV-2’s evolution

Bhattacharyya, an associate professor at Harvard Medical School, said that the virus had already developed into a more severe disease before the introduction of Omicron. Bhattacharyya says, “We are dealing with a virus that has become more severe over the years.”

An analysis in the UK showed that the Alphavirus is 4 times more likely than the first virus to cause death. Delta can transport patients twice as often to hospitals as the alpha version.

“Omicron could be a slight step back in severity. Bhattacharyya says that Omicron is likely to be more severe than the original virus. Bhattacharyya says that the term “softer” is not the norm or the path to evolution.

Omicron wasn’t the only virus created from the delta. This virus was an old version that was popular in 2020. According to Bhattacharyya, omicron could have more severe consequences than the parent virus.

There is no way to be certain that the next version will be faster. This could be the most difficult version to date.

Stephen Goldstein, an evolutionary biologist at the University of Utah, says that “I think it’s really not clear which direction this virus is going.” “We know that it is extremely difficult to predict the trajectory of this virus’ evolution. It is almost impossible to predict the trajectory of this virus.

How will COVID-19 evolve in the future?

SARS-CoV-2 can be spread from one person to another. It is most common in the early stages of a person’s illness, and often before they become aware that they are sick. The virus is currently mainly affecting people with respiratory issues. The virus is not yet in the lungs, but it could be fatal.

SARS-CoV-2 can be grown by causing mild to moderate upper respiratory tract disease. Gupta, from the University of Cambridge, says that SARS-CoV-2 does not have a survival strategy for causing severe disease. Cambridge University.

A new variant must spread quickly to the nose and airways in order to compete with older versions. It is not essential that the new variant has the ability to affect cells deep in the lungs. The new variant will likely be highly effective in clearing the immune system and other antibodies as an increasing number of people become resistant to SARS-CoV-2 or its variants.

Future versions of the device will be able to penetrate and expand the upper respiratory tract and resist escape.

Bhattacharyya says, “Whether these changes also make the new version more severe or less severe that’s up to you. That’s luck.”

Not all options should be considered.

Surprisingly, this idea isn’t so bad. This suggests that the wave after this omicron could have more devastating effects than the Delta wave.

Goldstein however suggests that it is impossible to account for the immunity of individuals because of another factor.

The body’s immune system becomes more vulnerable as the virus spreads. The SARS-CoV-2 immune systems are rapidly growing in the United States, according to a population scale. It is possible that the affected population could be more than half of all Americans. This percentage could rise to 80-90% after the omicron increase. More than 60% have been vaccinated.

Numerous studies have shown that both types of SARS-CoV-2 exposure reduce the likelihood of getting a serious illness. Goldstein says that regardless of whether you have been infected before or after vaccination, you are more likely to experience a milder course than someone without immunity. Goldstein.

Any variants that may appear in the near future will likely be less dangerous than any previous delta variants. Dr.

Scientists expect that the next round of COVID-19, regardless of how it affects us, will not be as disruptive or damaging as the previous one. This is because the virus’s nature has changed but because our bodies are better equipped to handle it. virus. The virus.
