"Choosing stress relaxation allows more variation to survive."

    "The virus is also replicating, and because the repair mechanism of the virus itself is weaker, it is easier to accumulate mutations."

    "The variation of the virus can not be completely preserved, but also depends on choice.

    Some mutations affect the survival of the virus, so it will be selected and abandoned, and those that can make the virus survive better are more likely to be fixed.

    But the choice is not static, and it will change with many factors. "

    "In short, the patient''s immunity is relatively weak, and the pressure of selection is relatively weak. The virus can ''play freely'' and mutate. Some mutations that will not occur under normal circumstances..."

    Wu Mian said, frowning.

    "Miss Wu, I heard that the virus tends to get weaker and weaker." Zhang Zimo asked.

    "Normally speaking, it''s a matter of high probability. The logic is very simple and cruel, because the mortality of patients infected with powerful virus is very high." Wu Mian said, "so when Tianhe found only 13 virus variants at that time, the headmaster reported the situation to the top and decided to gamble."

    Bet

    It is inconceivable that this sentence is used in such a serious matter.

    However, as clinical directors, they both know that the diagnosis and treatment of many diseases are not clear, and the situation of looking at luck emerges one after another.

    But the content behind this bet is too serious for everyone to think about.

    "I''m lucky. At least I haven''t encountered a very rare situation so far." Wu Mian said faintly. "The virus carried by the patient found by Zhong''s team has changed after selective stress relaxation. For the time being, it should not be fatal, but an insignificant change."

    "Miss Wu, will there be a big change?"

    "It''s possible that we''re talking more about the Spanish pandemic. According to its process, it''s estimated that it will take more than 1 billion people to cultivate, mutate and choose to mutate into a more powerful virus by chance." Wu Mian youyou said, "it''s only right not to encounter a small probability event, not a hero aura."

    "Stronger?" Zhang Zimo''s heart sank.

    "Yes, director Zhang, you can say it directly."

    "Mr. Wu, I read the report and feel that the virus this time is perfect. Now it is estimated that the incubation period is 10-14 days. If individual patients exclude the error of detection, the incubation period is as high as 21 days. The incubation period can also come on. The carrier has no symptoms, and will become seriously ill soon after the symptoms appear."

    "Hehe, except Tianhe City, no patient has died in Zhejiang Province." Wu Mian smiled.

    "That''s..."

    "The lethality of the virus is slowly decreasing, and the medical resources are relatively sufficient, so the mortality is very low. This will also create an illusion..."

    "What illusion?"

    Wu Mian didn''t answer this question. He just smiled. The "Scar" on his face seemed to live and was very happy.

    "It should be no problem for the time being. After all, a city with tens of millions of people is unlikely to have fatal mutation in a month or two."

    "Miss Wu, what is the fatal mutation you said?"

    "For self limiting diseases, the survival rate of young people is very high. After all, is immunity high? Once there are antibodies in the body, once the antibodies play the opposite role in the process of virus infection: they help the virus enter the target cells and improve the infection rate, it is more disgusting."

    "Is that the ade effect?"

    "Well, there is another rare change. I highly doubt the" Dong Dong ~ "knock on the door of the Spanish pandemic.

    "Who?" Chu Zhixi asked.

    "It''s me, Zheng Kaixuan. Is Mr. Wu there?"

    "Wait a minute, Professor Zheng."

    Chu Zhixi changed his clothes and went to open the door.

    "Miss Wu is busy?" after opening the door, Zheng Kaixuan saw Wu Mian sitting straight at the table looking at the computer.

    "Please come inside," Chu Zhixi said.

    "No, keep your distance," Zheng Kaixuan said with a smile, "I''ll come back later."

    "Professor Zheng, I''ve finished reading it. What can I do for you?"

    "Miss Wu, I have something strange to tell you."
