Ren Haitao, Chen Lu and Professor beilac stayed in a nearby hotel. They soon arrived at the station and waved upstairs to have a rest.
"Girl, did you read the mail?"
After professor beilac left, Wu Mian asked.
"No, what''s the matter?"
"The headmaster sent it." Wu Mian said cautiously. "The laboratory is looking for mutant strains, but now it seems ideal. Although there are 13 kinds of viruses, there is no special change in lethality and infectivity."
"Oh? So the mutation speed is not fast?"
"Current data show that virus mutates only half as fast as influenza," said Wu Mian in a relaxed voice. "Most importantly, there is no extreme situation."
"Extremely long infectivity, extremely long incubation period, and rapid onset of severe disease once it occurs. It is difficult to progress to this level. It should not appear without screening for one or two years." Chu Zhixi asked.
"HMM." Wu Mian nodded, took off his mask and took a deep breath of Tianhe air.
"Put on the mask!" Chu Zhixi was startled.
"There is no problem in a ventilated environment," Wu Mian said.
"That''s not good!" Chu Zhixi stood on tiptoe, took the mask belt from Wu Mian''s hand and hung it on his ear.
"There are more and more cases of spike protein d614g mutation. The functional characteristics of S protein have been compared with aspartic acid and glycine at residue 614.
It was found that the retrovirus pseudotyped with g614 was more effective than that pseudotyped with d614, and the infection efficiency increased about 9 times. "
"No mutation was found, especially the cross mutation with influenza virus."
"No, not yet."
"Miss Wu, what do you mean?" a little nurse asked curiously behind her.
"That is to say, the virus in Tianhe City is not the same as it was half a month ago," Wu Mian said simply. "The infection is stronger, about twice as strong, but the severe toxicity is weakened."
"Er... Is this a good thing or a bad thing?"
"There is no difference between good and bad, which determines how to go next." Wu Mian said with a wry smile, "and we have to do our best to listen to heaven."
"Modern science is so developed that it can be calculated with a supercomputer." the little nurse said, "I thought Zhong Nanshan had information in his hand long ago."
"The virus is constantly mutating," Wu Mian said. "Although the changes are similar, there are basically eight variation directions."
"Which eight?"
"It''s too complicated. I won''t tell you." Wu Mian said, "it''s normal for RNA virus to mutate. There have been many mutations in spike protein, most of which have no effect on the virus, but these mutations can be used to trace the source of the virus.
Only a few mutations affect infectivity or pathogenicity. "
"Mr. Wu, what you said is too complicated to understand." the little nurse asked, "can you tell me when it will end? I see that the wechat group at home has also begun to respond at the first level. There are cases in our provincial capital."
She inquired with some concern.
"It''s hard to say." Wu Mian sighed.
"More than 100 years ago, Wu lien de can control the spread of plague. Now how can it be done?" complained the nurse.
"Did I tell you what the temperature was in Northeast China in January?" Wu Mian said. "Mr. Wu had no conditions at that time, so he could only isolate the patients with train skin. Is there any heating facilities? What should be done to isolate the patients from freezing death and frostbite?"
“……”
"This is not a stand-alone game," said Wu Mian. "At that time, as soon as I got off the plane and saw the news of the closure of the city, I knew it was a big deal."
"We also find it strange that the city was not closed when the s virus. But now in retrospect, no one thought it would be so serious."
"Closing the city is a means of isolation, and there are countless things to face after that.
How to ensure the livelihood of citizens? How to solve the basic problem of food and clothing?
How to deal with illegal vendors hoarding and driving up prices?
What if there are artificial rumors and panic? Should international influence be considered?
What if panic spreads and leads to more serious consequences? "
"I didn''t think about it at that time." the little nurse smiled. "I think our country can solve it."
"It''s hard to solve," said Wu Mian youyou.
The expert group is considering centralized isolation. All patients should be isolated and divided into mild and severe cases.
The test is not only the large infrastructure capacity - whether we can build a serious hospital and isolation space for mild patients, but also everyone''s feelings.
There are many elderly people, people with poor health and people with low immunity. What if the virus mutates and recombines? Although there is no problem with high probability, in the face of a new virus, who knows how it will mutate.
In case of the kind of virus Chu Zhixi just said, I''m afraid China will collapse directly.
At this point in time when we should bear historical responsibility, Wu Mian is also a little counselled.
After all, he is still young. At the thought of serious consequences... Even Wu Mian dare not continue to think about it.
This is only one of them.
Centralized isolation, once people continue to turn from mild illness to severe illness, inducing mass fear events, it will be really big.
It is conceivable how much pressure policy makers have to bear after the closure of the city.
Time is pressing, and the situation in Tianhe City has not been alleviated by the arrival of 3-4000 medical and nursing personnel; Nor has it been alleviated by the national support for living, production and protective materials.
In Tianhe City, even the air we breathe is solidified.
The traffic in the past has disappeared without a trace. The shops on the side of the road are closed, and the flashing neon has disappeared. Although it looks orderly, this cold and depression seems to silently tell everyone that the world is not the world it used to be.
Great pressure is on the shoulders of medical staff and the hearts of all citizens of Tianhe City.
It is a complex social problem whether he can bear it and when it will collapse. Wu Mian can''t figure it out.
But the only thing Wu Mian knows is that the time left for Tianhe City is running out, and the expert group must make a decision within the last three days.
Although the decision-making has nothing to do with Wu Mian, but the headmaster''s email came, Wu Mian still subconsciously thought about it.
Moreover, not only Tianhe City, but also the whole country is facing the same problem, either light or heavy.
Several people were silent and walked in the night of Tianhe City.
Everyone has a lot on their mind.
Passing by a community with tall buildings, Chu Zhixi looked up and looked up at the lights. Travel has been reduced for 4-5 days. People here don''t know whether it''s good or not.
On the balcony, there are faint figures who can''t stand loneliness.
Suddenly, a familiar song floated in the night.
[get up, people who don''t want to be slaves!]
