Gao Fei reported to Gu Yanan on the work of guiding the county in the past few days, "The work in Guanyun County is the same as in previous years, there are a few old comrades here, and the work is relatively easy.

Guannan County is a little worse, this year there are two new workers, the master has retired again, many of the precautions for catching wild mice in the wild are not very clear, I and Zhou Lao took a lot of effort to teach them. ”

Zhou Lao also echoed, "It's all routine work, and I'll sort it out into a written report and send it to Director Gu after a while." ”

As soon as Gao Fei entered the office door, he noticed that Gu Qingcen, who had been isolated and treated for more than two weeks, was now back to work.

Gao Fei took the initiative to greet Gu Qingcen, "Teacher Gu, you have come back to work, I feel like I haven't seen you for a long time." ”

Gu Qingcen showed his usual warm smile, "Since the explosion of the P3 laboratory, I have been isolated and treated for more than two weeks now, after testing by the hospital and our CDC, no highly pathogenic pathogens have been found in my body, and now that the isolation and treatment have been lifted, I should also return to the normal track of life." ”

Wang Xiaoxiao on the side sighed, "Gu Dashen, you are simply a miracle, the scale of the explosion in the P3 laboratory last time was so large, and there was a leakage of pathogens, the entire specimen library of our CDC was basically destroyed, but you were not infected with any highly pathogenic pathogens, you must be possessed by Oushen." ”

Gu Qingcen was still smiling, "Maybe it's because when the explosion occurred, my protective clothing worked." ”

Wang Xiaoxiao: "The tests done by the hospital and our CDC laboratory for Gu Dashen are all nucleic acid tests with relevant pathogens, and a negative nucleic acid test indicates that there are no related pathogens in the body, because with these test results, Gu Dashen can be released, otherwise it will take 10 days and half a month to wait for those serum tests."

Gu Dashen, you must be uncomfortable in the isolation ward, since you come out, it can be regarded as a catastrophe, and there will be blessings, shouldn't we celebrate together? Do you want to discuss the location of the dinner? ”

Lu Li glanced at Wang Xiaoxiao and said leisurely, "You want to have dinner so much?" Do you want to turn back into a cotton? ”

Lu Li mentioned the cotton stalk again, Wang Xiaoxiao was not annoyed this time, and responded with a smile, "It's summer, I've eaten fruit weight loss meals for three days in a row, and I have an occasional dinner, and eating some meat is not in the way." ”

Gao Fei seemed to suddenly remember something, and patted his head, "Look at my brain, I almost forgot, this time I went to Guanyun County to guide the work, I bought a box of freshly ripe Gala apples on the side of the road, and put it in the car, I forgot to take it just now, I will take it now." ”

Gao Fei trotted downstairs to get the apples, and Wang Xiaoxiao, Lu Li, and Gu Qingcen were discussing the dinner.

Gu Yanan stared at the computer screen, just now the CDC gave her a test report, which was a report on the detection of antibodies to related pathogens in Gu Qingcen's blood.

All items from top to bottom are positive.

The CDC laboratory used all kinds of antibody detection reagents currently in stock, and the results showed that Gu Qingcen's blood tested positive for antibodies against various pathogens, even several highly pathogenic pathogen antibodies.

And all positive antibodies are IgG antibodies, and IgM antibodies are negative.

In other words, Gu Qingcen has been infected with a variety of highly pathogenic pathogens, and judging from the titer of antibodies, the infection time was at least half a year ago, and some times were even longer.

There are two possibilities for this situation, one is that Gu Qingcen has been infected with these pathogens, and the other is that he has been vaccinated against the corresponding pathogens.

Gu Yanan analyzed the possibility of these two situations in his mind.

If Gu Qingcen had ever been infected with these pathogens, no matter which one of them he took out, the lethality would reach 60 or 70 percent, including the Ebola virus, Lhasa fever virus, and West Nile virus, and these would have reached more than 90 percent.

If it is the second case, vaccinated with the corresponding pathogen, this is also unlikely, because there are some highly pathogenic pathogens, and there are no commercial vaccines yet, many vaccines under development are still in the clinical trial stage, and some virus vaccines are even in the animal experiment stage, and Gu Qingcen has no chance to come into contact with them.

In the 7 years that Gu Qingcen has disappeared, what has he experienced?

Gu Yanan finished reading the serum test report fed back from the laboratory, and while thinking about various possibilities, he unconsciously raised his head and stared at Gu Qingcen opposite.

Gu Qingcen, who was discussing the place of the dinner, noticed Gu Yanan's strange eyes, "Director Gu, why are you looking at me like this?" What went wrong? ”

"I have here an electronic version of the test report I just received, send it to you, you can take a look."

Gu Yanan didn't say anything about the content of the test sheet, because he wanted to protect Gu Qingcen's privacy.

After Gu Qingcen read the test report on the computer, he knew the reason for Gu Yanan's serious face just now, and explained to her with a smile, "I have participated in several drug trials when I was abroad before, most of them are vaccines that have entered the clinical stage, and some of them are vaccines that have just finished animal experiments and have not yet been approved for clinical trials. ”

"No vaccine approved for clinical trials? How can you experiment with people? Gu Yanan asked in surprise.

"Researchers from some foreign institutions want to do a preliminary human experiment on long-term research before entering clinical trials, which requires signing a confidentiality agreement with them, and the remuneration for this kind of activity is very high."

Gu Yanan felt sad and distressed for Gu Qingcen, he didn't expect him to have such a bad time abroad in the past few years, and in order to make money, he actually went to participate in human experiments on various drugs, what stimulated him to suddenly cut off contact with everyone?

Gu Yanan's expression changed from question to distress, Gu Qingcen seemed to be very satisfied with this expression, and comforted: "Everything has passed, I am alive and well now, and because of many blessings and misfortunes, such a big thing happened in the P3 laboratory, and I was not infected, and I am still alive because I received all kinds of strange vaccines." ”

"When you were treated next door to the hospital, why didn't anyone say anything, and we were all worried."

Gu Qingcen: "When I was in the drug experiment, all kinds of information were kept confidential to the subjects, so I didn't know which vaccines I had received. ”

Gu Qingcen's explanation was perfect, and Gu Yanan's doubts were eliminated.

Wang Xiaoxiao listened to it on the side and guessed one or two, but she didn't care about what Gu Qingcen had experienced before, she was more concerned about where to eat at the next dinner.

"Sister Yanan, do you have any suggestions for a place to have a dinner?"

Gu Yanan was successfully diverted from the topic, "Chinese, Western or Japanese, which one do you want to eat?" ”

"Of course it's Chinese food, but there are so many types of Chinese food, we have to choose a good one......

Wang Xiaoxiao was rummaging through the Internet for restaurants that could be suitable for dinner, when the landline phone on the desk suddenly rang, and Gu Yanan picked up the phone.

A familiar voice came from the phone, it was Gu Jiashu.
