The strain mutates, the more it recovers, and the new corona virus becomes more dangerous?

On August 20th, more than 22 million people were diagnosed! More than 780,000 people died! For months, the new crown virus has spread around the world, and the alarming "lethality" is worrying.
, especially recently, in Malaysia, South Korea and other places found the virus mutated strain of the news, further "institive" people's sensitive nerves.
the new corona virus spread faster and more deadly when it mutated? Why does the patient have a "fuyang" condition after the patient? Will vaccine development be affected by virus mutations? These have become the focus of the public and eager to be answered questions.
found a mutated strain, a new viral genealogy of the new crown virus "72 changes"? Recently, new strains of the virus have been found in many countries around the world.
latest case of virus mutations of concern, from Malaysia.
16th, Malaysia's Health Minister Noor said that of the existing confirmed cases, four cases of D614G mutant strains have been confirmed.
just a day after Indian media reported that Indian researchers had discovered 73 variants of the new crown virus strain in the eastern state of Orissa.
, lead researcher at the University of India, said researchers sequenced 1,536 samples, including 752 clinical samples, and eventually reported two new viral linees in India for the first time.
, WHO has previously noted that scientists discovered the virus mutation as early as February, and that the strain has spread in Europe and the Americas.
russia also said at the end of June that the new coronavirus transmitted in Russia had mutated, but experts believe the mutation did not lead to a major change in viral symptoms.
Japanese experts pointed out on August 9th that a small amount of base mutation had occurred in the popular strain in Japan, or had spread from Tokyo since late June, and a day later, South Korea reported three cases of "spike protein" mutations affecting infection from abroad. In addition, Vietnam, Iceland and other countries have reported the discovery of new crown virus mutation.
the mutant virus spread faster and more deadly? Scientists disagree, but will the mutation speed up the spread of the new corona virus? Recently, Malaysian officials announced the confirmation of four cases of D614G mutant strains, pointed out that the mutant strains are "10 times more contagious", and then triggered widespread discussion.
, WHO's chief scientist, said in July that laboratory studies had found that the new coronary virus D614G mutated, or led to accelerated replication, transmission or increased replication of the virus.
but there is a big difference between laboratory results and changes in the actual spread of the virus.
Paul Tambyah, senior adviser at the National University Hospital of Singapore and president-in-waiting for the International Society of Infectious Diseases, said there was evidence that the new coronary strain of the D614G mutation was spreading in some areas while the mortality rate was declining, meaning it was less lethal.
, however, a study published in the International Journal of Infectious Diseases in May suggested that infections with strains with D614G mutations may be associated with higher rates of death.
characteristics of strains that cause deadly infections in European populations are carrying D614G mutations, the researchers said.
but the researchers say the study lacks experimental evidence.
rare cases of fuyang attract attention to how long antibodies can be maintained? Worryingly, we are not only facing the challenge of mutated new corona viruses.
recently, in South Korea, Russia and other countries in the new crown cure patients, there have been rare cases of patients after the "fuyang", so that healers fear re-infection.
However, several French medical experts believe that some cure patients have tested positive for the new coronavigic virus, which may be incorrectly related to the test results, and Yv Gaudin, a virologist at the Paris-Sacre Institute for Integrated Cell Biology, said it may be that the virus in the patient's body has not been completely eliminated.
, the Fuyang case also triggered a study of how long new coronary virus antibodies can be present in the human body.
16.7 percent of patients still have enough antibodies 65 days after symptoms appear, according to a study published in July.
, chief infectious disease specialist at Russia's Health Ministry, said there was no scientific data on how long antibodies could last in people infected with the new crown and how many were produced depending on the severity of the disease.
but it's safe to say that most people who have been sick produce antibodies.
addition, even if a virus-specific antibody reaction is not detected, patients with neo-coronary mild illness trigger a strong memory T-cell response, according to the latest issue of Cell magazine.
T-cell response from natural contact with or infection with the new coronary virus may be an important immune component in preventing the cause of the new coronary severe disease.
the virus mutation cause vaccine development to fail? Experts: Less likely to face the many unknowns of the outbreak, vaccines have become the real "killer" to defeat the virus.
, is the vaccine also effective against mutant viruses? Several experts say the current virus mutation is less likely to cause vaccine development to fail.
the other hand, in the study of the new crown vaccine has enough sites, can produce immune protection effect, many gene site mutations, will not necessarily make the vaccine ineffective.
On the other hand, the new coronavirus mutates faster, but also in the coronavirus class, the current rapid development of big data research, once there are new mutations, can quickly guide the improvement of the vaccine.
, in order to control the spread of the epidemic as soon as possible, the global multi-country speed up the pace of vaccine research and development.
Russia has registered its first new crown vaccine, Satellite V.
India's prime minister said the country will mass-produce a new local crown vaccine, South Africa on the 17th launched a second clinical trial of the vaccine, Cuba's home-made vaccine is about to be put into clinical trials.
despite reports of vaccine development, experts warned that people should remain vigilant and comply with vaccination rules before the vaccine is officially launched.
