Chapter 1164 Enlightenment (Blood Donation Plus Series 091.092)

本章加更是为了感谢书友“1龙聋笼”在2019年5月14日和2019年11月14日所捐献的两次全血而加更。之后还有两章为他的加更。

The inquiry lasted for almost two hours, during which the two staff repeatedly confirmed to Sun Lien the contact process between him and Xiao Linfeng through various means.

It is said to be repeated confirmation, but in fact it is to repeatedly confirm one thing through different methods-whether Xiao Linfeng and Xiao Linxun have direct economic contacts with Sun Lien.

This kind of question would make people feel a little offended, but considering Song Wen's instructions before and the sudden extra police cars outside the door, Sun Lien deeply felt that it would be better for him to say something.

After answering all the questions, it was five o'clock in the afternoon.The two staff members exchanged glances with each other, then stood up synchronously and began to pack their things in a tacit understanding.While they were packing their things, they signaled to Sun Lien that he could move freely, and said, "We have already understood the basic situation, and we have received the recording - the recording in your mobile phone can be processed freely."

Sun Li'en stood up, stretched his waist, and then asked, "Then...do I still have to stay in the room all day long and not go out? Or can I go to work in the hospital?"

"You can go." The two staff members said with a smile, "Dean Song may have been a little too nervous before, but now there is no problem." They looked at Sun Lien's nervous look and added, "As long as you are in the country , then there will be no trouble. If Xiao Linfeng still has contact with you in the future, you can also report to Dean Song like this time—she can contact us. "

"Is this information... useful?" Sun Lien asked a little nervously, "Should it be of some help to trace the source of the virus and continue research?"

The two staff members looked at each other again, and the person in charge of asking questions suddenly asked, "Dr. Sun, virus origin tracing is a very serious scientific work, and we must speak with indisputable scientific results."

"Yes." Sun Li'en nodded, and then said a little puzzled, "But the result of this experiment itself is scientific and objective..."

"Its scientificity and objectivity remain to be seen." The staff member said, "Even if it is completely correct and accurate, with evidence of this strength alone, we cannot be sure where the epidemic originated. The experimental process Whether there will be contamination during the detection process and whether the results are accurate, these issues require scientists and researchers to continue to study."

"But they don't talk about martial arts so much..."

The staff member smiled and said, "We are a responsible big country, so we have to look like a responsible big country. We have to be responsible to the world, to the people, and to history—just tell us what evidence we have." What evidence. We were bitten by a dog, so we can't hold the dog down and take a bite to get revenge, right?"

The two staff members laughed together, and the staff member recorded just now said seriously, "Our attitude has always been clear. Virus traceability is a scientific issue and should be left to scientists to solve."

It wasn't until after the two staff members were sent away that Sun Li'en realized... He didn't know which department staff the other party was.

Well, don’t ask what you shouldn’t ask, and don’t know what you shouldn’t know.He sighed, then turned around and walked into the room to start taking a bath - no wonder those little girls always said that they were going to take a bath, anyway, taking a bath if there is nothing to do, it can really relax people's tense body and mind at the same time.

Five new confirmed cases were added in Yunhe City yesterday, and there were no confirmed cases in the other 5 city-level areas in northern Hunan Province.Among the patients currently receiving treatment in Yunhe's hospital, there are less than 16 critically ill patients, and about 4000 ordinary and mild patients.

According to the current discharge rate of nearly 1000 people per day, in another week... that is, around March 3, Yunhe should be able to achieve the goal of 20 new additions.

It's finally about to win.Sun Lien was a little happy at first, but now he is not happy at all.

The epidemic in Italy continues to spread, and its severity continues unabated.

Judging from the current rate of increase, the epidemic in Italy is far from reaching its peak.According to basic epidemiological knowledge, only after the positive rate of large-scale PCR tests has dropped significantly, can it be confidently said that "the epidemic is coming to an end."

On the Italian side, PCR testing capacity is weak.As a developed country, Italy currently has less than 8000 PCR tests per day. This level is sufficient for research, but it is not enough to deal with infectious diseases.

Italy has a population of 8000 million, and the developed transportation leads to a huge population flow.The detection level of 8000 cases per day is not even considered "enough". According to estimates based on the transmission speed of the new coronavirus, this PCR level must be increased by at least [-] times to find out before the epidemic spreads to the next order of magnitude. All infected.

The detection level cannot keep up, which is only one of the reasons for the serious epidemic situation in Italy.

As a country with a long history, most urban areas in Italy have been built for more than a hundred years.The old city has its own unique culture and layout design, and this layout design not only brings a beautiful city appearance, but also objectively provides conditions for the spread of infectious diseases.

Narrow windows, difficulty in indoor air circulation, aging sewer pipes, high residential density...all these conditions objectively reduce the difficulty of spreading infectious diseases.At the same time, cultural differences also make most Italians a high-risk group.In their culture and social habits, it is normal behavior to greet each other face-to-face, and warmly hug and shake hands.It is impolite to keep your distance from neighbors and friends.Only sick patients need to wear a mask, and breathing fresh air without covering is the key to staying healthy.

What is even more frustrating is that ordinary medical surgical masks and N95 masks are not friendly enough to the facial features of Italians.

Most of the facial features of Westerners are relatively three-dimensional. Except for Jews, French and Italians generally have relatively high noses.In addition to bringing them a larger nasal cavity to adapt to the environment, the high bridge of the nose also hinders the effect of surgical masks on their faces.Although many Italians wear masks themselves, they simply choose to expose their noses because their noses are so uncomfortable.

There is another high-risk factor that makes the new coronavirus cause a high mortality rate in Italy-their medical system.

It's not that Italians have a bad medical system, on the contrary, their medical system is quite high.With the support of a high-level medical system, the population over 65 years old in Italy accounts for more than 22.8% of the total population.In patients with new coronavirus infection, age is an independent high-risk factor.

At the same time, Italy's healthcare system is under unprecedented pressure.

In addition to the suffocating tide of medical visits, Italian medical workers must also face the lack of epidemic prevention materials, overtime work, and the more worrying problem of medical staff infection.Italy's own production capacity of anti-epidemic materials is not enough, and as the epidemic spreads in various European countries, the already insufficient anti-epidemic materials are even more tense.

In order to ensure that their countries have enough anti-epidemic materials, many EU member states have begun to issue export bans, stopping the anti-epidemic materials ordered by other countries in the middle.As the world's largest exporter of masks and anti-epidemic materials, the epidemic in China has not completely disappeared.At the same time, various production enterprises are still in the stage of rising output.It will take time to establish a new production line and mass-produce epidemic prevention materials.

Italy is now almost an outcast of the European Union—all EU countries have issued regulations prohibiting the entry of Italians, and all countries in the same union are anxious to protect themselves. No country is willing or able to extend to Italy. lend a helping hand.

And China, which has just recovered from the epidemic, has provided them with valuable assistance.

On the day Sun Lien was grounded, he received the news that the expert team of Xihua Hospital had transferred the director of the Respiratory and Critical Care Department, the head nurse of the Pediatric ICU ward, and a large number of other experts who were still in Sichuan.They hurriedly boarded the plane, arrived in Shanghai directly, and boarded a chartered flight to Italy.

In addition to doctors and experts in the field of disease prevention and control, the plane even brought an Italian professor who taught at Shuzhong University.She used to be in charge of translation this time.

Flying to Rome with these experts, there are also 31 tons of anti-epidemic materials donated by China.These materials include ICU equipment, ventilators, medical protective equipment and antiviral agents, etc.

When Germany and France, the two major manufacturing centers in Europe, announced restrictions on the export of medical protective equipment, China decided to sell 1000 ventilators, 200 million masks, [-] protective suits and [-] PCR testing reagents to Italy. box.

This is the Chinese way of life - do not do to others what you would not have done to yourself.We just went through a catastrophe, and as human beings, we don't want any country to go through the pain that we have gone through.Even if the supplies are still tight, even if there are new patients diagnosed every day in Yunhe, as long as it can help, then it must be done.

Sun Lien returned to his job safely, which made the colleagues in the medical team very happy.

"We thought you were quarantined at first." Bruen approached Sun Lien and said, "After asking Hu Jia, we found out that you were quarantined because of other things."

"Indeed." Sun Li'en nodded, he still didn't know if he could tell others what he had heard from Xiao Linfeng.So, he could only think of a way to confuse this matter, "Didn't I attend a meeting before, and I had other things to deal with after the meeting, which tormented me all night-won't I just lie in the room yesterday Make up for sleep."

Bruen had no doubts about him, after all, Sun Lien still had a high degree of credibility with him.He suddenly remembered something and said, "Oh, by the way, do you still remember what I told you about my nephew?"

"Remember, that's the ground crew at the air force base?" Sun Li'en nodded and said, "His observation period has ended?"

"Yeah." Bruen nodded, and said with some gratitude, "It's been a long time anyway. He hasn't had any symptoms—but he told me two days ago that the doctor gave him an antibody test... He's positive."

Antibodies are the result of the normal immune response of the human body. When an antigen invades the human body, the immune system will synthesize an immune substance that can fight against the antigen within a period of time-this immune substance is an antibody.Antibodies can function as markers of immune recognition and deposition.Immune recognition enables macrophages to recognize and phagocytize antigen-antibody complexes, while the antigen-antibody complexes themselves can prevent pathogens from continuing to invade human cells and lose their ability to move.

In other words, antibodies to the new coronavirus were detected in Bruhn's nephew, which means that he had been infected with the new coronavirus.

As a virus that has not yet had a breakthrough infection mutation, having been infected means that the recovered person will not be infected with the virus again for a considerable period of time.

Although some pathogens are exceptions, in most cases, the fact that the human body has immunity after infection will not change.

"That's good." Sun Li'en thought for a while and then asked, "Have you done a PCR test for him?"

"No." Bruen shook his head. "The CDC officials don't know what's going on. They don't allow the use of PCR kits from commercial companies, and they don't allow PCR kits from other countries to enter the United States. They can only use Their own — this kit is said to have questionable accuracy.”

Good guy... Sun Lien took a breath, patted Bruen on the shoulder and said, "Forget it, anyway, your nephew has no symptoms, and now the antibody is positive, so he is at most an asymptomatic infection..."

Speaking of this, Sun Li'en suddenly had an idea.

"When was your nephew diagnosed with vaping pneumonia?" Sun Lien asked pretending to be nonchalant, "I remember you said... last September?"

"October." Bruen corrected Sun Lien, and then said helplessly, "The kid was very sick at the time, and even entered the ICU. We all thought he might not make it through."

"What's his current antibody titer?" Sun Li'en continued to do his own business. He made a look in front of the nurse's station in the green zone to check the doctor's order, and then asked "casually", "The recovery from our hospital here The concentration of RBD IgG (antibody to S protein on the surface of the new coronavirus) in patients is basically around 1000-2500."

"He probably has... more than 200?" Bruen was a little uncertain. "His antibody titer is quite low anyway. I think it may have something to do with his previous drug abuse."

It is still unknown to what extent the antibody level in the recovered patients of the new coronavirus will reach, and whether the antibody titer level in their body will decline over time.And this unknown also casts a cloud of gloom on the fight against the virus.

According to the request for assistance from the higher authorities and other research groups, the North Fifth District is carrying out tests on the antibody titer levels of recovered patients from the new coronavirus.So far, tests have mainly shown two characteristics-the antibody titer levels in middle-aged and elderly recovered people are generally higher than those in young people.At the same time, RBD IgG antibodies cannot be detected in some recovered patients.

The news that not all recoveries are immune is enough to cause headaches.What is even more troublesome is that the antibody levels of young people are low.That could mean younger recoveries face a greater risk of reinfection later on.

And Brun's nephew's RBD IgG antibody level is more than 200, which does not directly explain the problem-he may indeed be an asymptomatic infected person and recovered.It is also possible that...the new coronavirus has been infected in October.

It's pointless to worry about this now, it's better to focus on the things in front of you.After being educated by the two staff members before, Sun Li'en calmed down a lot.

"Okay, I wish him good health." Sun Lien finished his perfunctory work, then stretched his waist, "Let's go, let's get into the cabin!"
