The latest research by American scientists has found that SARS-CoV-2 has mutations that can more easily infect human cells.

According to CNN reports, scientists at the Scripps Research Institute in the United States said that the experimental results showed that the CCP virus had mutations, which caused changes in the spine protein and invaded human cells more completely during the infection process.

The virologist Hyeryun Choe, who is leading the research, said that the virus that produces the mutation is far more infectious than the unmutated virus. "Our data is very clear that the virus becomes more stable after mutation."

However, the research team emphasized that more cases are still needed to verify this finding. At present, the team has sent the research results to the authoritative American scholar Haseltine (William Haseltine).

Hastings believes that this result explains the reason why covi spreads easily in the United States. This is a major discovery, because it shows that the virus can change, magnify its own advantages and human disadvantages.

Prior to this, some experts have pointed out that SARS-CoV-2 is very cunning and has a large amount of mutations, which makes the developed vaccines with limited efficacy. Moreover, even if you have been infected with a virus and have antibodies in your body, you will still be infected with a new virus strain.

According to a report by the Central News Agency on 29 April, the virus continued to evolve and mutate. Research teams from various countries have actively studied the virus types of the Chinese Communist Party’s virus strains and are committed to studying the virus mutation.

However, the Chinese Academy of Sciences in Taiwan said that some teams judged the virus strain typing for only one mutation, which may underestimate its complexity. The research team of the Chinese Academy of Sciences found that the 6 major virus strains in the world can be typed by 13 major mutations. There is imprint distinction.

The Chinese Academy of Sciences said that this observational study showed a positive correlation between the amount of viral mutation and lethality and an increasing trend over time. The research data is mainly taken from the Global Influenza Data Initiative (GISAID).

At present, the amount of data is accumulating rapidly and new virus mutations continue to be generated, indicating that the evolution of the CCP virus is still in progress.

As early as February 26, after the first confirmed patient appeared in Brazil, the local teamed up with British scientists to carry out an emergency "viral gene sequencing" of this patient. It was found that the virus in the patient's body is different from the virus gene published by Wuhan.

Scientists wrote the first report of the CCP virus in South America that analyzed the viral genes taken in the patients’ nasopharynx and found that Brazil’s “Brazil / SPBR1/2020” virus genome and the “Hu-1” reference strain released by the CCP different.

Scientists believe that this means that the virus has begun to mutate during its spread.

The results of this study prove that the virus is quite cunning, and it mutated again when people did not know its details. It has added difficulty to humans to overcome the virus.

However, the cunning of the CCP virus is not only reflected in mutations in transmission, but it also attacks multiple organs of the human body, including the heart, liver, spleen, lungs, and kidneys.

In addition to being known to block the respiratory and blood supply system, the human immune system, and the reproductive system, Beijing Ditan Hospital said that the virus can also infect the nervous system and cause encephalitis.

Beijing Ditan Hospital found that in the genetic sequencing of a 56-year-old patient, the CSF pneumonia virus was found in the cerebrospinal fluid of the patient and caused viral encephalitis.

In the diagnosis and treatment plan announced by the authorities, the revision also mentioned that the patient's brain tissue was congested and edema, and some neurons degenerated, confirming that the virus will invade the human central nervous system.

The cunning and toxicity of the virus has killed more than 7 million people worldwide and killed more than 420,000 people. People are expecting the virus to subside soon. But He Dayi, the leader of four research teams at Columbia University, said that the CCP pneumonia virus may coexist with humans.

He once told VOA, "This virus may coexist with humans, and as the weather changes, it will move from the northern hemisphere to the southern hemisphere and reappear next season."
