Chen Yaozu: "I said, here's the thing, more than a month ago, I was on the night shift, and when I was centrifuging a blood sample, I accidentally broke a blood collection tube, and at that time I only collected a new tube of blood from the patient and simply disinfected the centrifuge.

I didn't take this matter to heart until a few days ago, my mother had a cough, fever and night sweats, and then fainted while doing cleaning work at the Grand Theater and was sent to the hospital.

I began to look for the cause, only to remember that it might have been caused by a laboratory operation mistake more than a month ago, and I checked the patient's medical records at that time, and found that he was indeed a tuberculosis patient. ”

That's how it happened.

Gu Yanan didn't expect that at first, she just speculated that Chen Yaozu was a laboratory doctor, and she might have been infected when she came into contact with a tuberculosis patient when collecting blood from a patient, but she didn't expect that what happened was an infection caused by a mistake in the experiment.

"When the blood collection tube breaks under high-speed centrifugation, it produces a high concentration of aerosols, and after the blood collection tube ruptures, do you disinfect the laboratory thoroughly, including air disinfection?"

"No, because there was a strong smell on the second day of air disinfection, and I was afraid that the leaders would find out, so I simply sprayed the inside of the centrifuge with alcohol."

Another one who concealed it and did not report it, causing a catastrophe.

The aerosol formed by the blood containing the tuberculosis bacilli will spread throughout the room, and once someone enters, there is a possibility of infection, so everyone who has been to the laboratory room must be screened for tuberculosis.

Gu Yanan looked at the panicked Chen Yaozu in front of him, and sighed: "There are some things that can't be hidden, but fortunately, tuberculosis can be cured, and measures can be taken in time to stop it in time." ”

Over the next few days, the CDC emergency team was busy disinfecting the environment of the Grand Theatre and the laboratory department of the Binhai District Hospital, while screening staff for tuberculosis in both places.

Three more patients infected with Mycobacterium tuberculosis were found during screening at the Grand Theatre and two patients infected with Mycobacterium tuberculosis were also found in the laboratory department of Binhai District Hospital, but fortunately they were all in the early stage of infection and had no serious complications.

The laboratory of the Center for Disease Control and Prevention also cultured the sputum of all patients, and the cultured Mycobacterium tuberculosis conducted antimicrobial susceptibility tests, which confirmed that they were all susceptible strains of the current first-line anti-Mycobacterium tuberculosis drugs, and the treatment was relatively smooth.

Lianhai Center for Disease Control and Prevention, Emergency Office.

Gu Yanan is writing a summary report on this tuberculosis cluster outbreak.

During the night shift, Chen Yaozu, an examiner from the laboratory department of Binhai District Hospital, was on improper operation, which caused the blood collection tube in the centrifuge to be centrifuged at high speed to fragment, resulting in the blood containing tuberculosis bacilli in the blood collection tube diffusing aerosol to contaminate the entire laboratory.

Chen Yaozu did not report the incident in a timely manner, did not leave corresponding records, and did not thoroughly disinfect the laboratory, resulting in Chen Yaozu himself being infected, and the two staff members who later entered the laboratory to work were also infected with Mycobacterium tuberculosis.

Chen Yaozu did not show clinical symptoms after being infected with Mycobacterium tuberculosis, but his body excreted Mycobacterium tuberculosis, causing his mother Chen Xiaohua, who lived with him, to be infected.

Chen Xiaohua, who works at the Grand Theatre, transmitted Mycobacterium tuberculosis to the staff around her, including five female troupe girls and three elderly support staff.

As of today, the patients with the tuberculosis outbreak in the Grand Theater have been discharged from the hospital, and the patients who are discharged from the hospital will continue to be treated with anti-tuberculosis drugs in the next six months to one year.

The CDC's Department of Slow Communication will follow up on the progress and effect of treatment.

After writing the summary report, Gu Yanan filed the report.

The three interns also finished their rotations in the emergency office and prepared to go to other departments.

Intern Xiao Jia: "The emergency office is really the most exciting place for the CDC's work, and when I watched Director Gu investigate Chen Yaozu before, that posture simply caught up with the detective." ”

When Gu Yanan was investigating Chen Yaozu in Binhai District Hospital, only intern Xiao Jia was by his side, Wang Xiaoxiao was very interested in the situation at that time, and asked Xiao Jia to repeat the situation at that time.

Xiao Jia's description was colorful, and at the end he deliberately added, "I think Director Gu was completely deceiving Chen Yaozu at that time." ”

Gu Yanan: "Not exactly, Chen Yaozu's demeanor at that time showed that he must have something to hide, and it was related to this epidemic, so I explained the possible situation, fortunately he explained in time, otherwise it would have taken us a lot of time and energy to find the tuberculosis patient who had gone to Binhai District Hospital for treatment." ”

Intern Xiao Jia: "If Chen Yaozu didn't say that the experiment was wrong at that time, we could only think that the tuberculosis patient who went to Binhai District Hospital infected the laboratory department, and the culprit might not be able to find Chen Yaozu." ”

"As long as things are done, they always leave traces. Chen Yaozu lost a tube of a patient's blood sample due to an operation error, and he took another tube from the patient, which is a trace, and if you investigate carefully, you can also find the abnormality in it. ”

Intern Xiao Jia sighed, "Skynet is magnificent, negligent but not leaky." ”

Wang smiled: "This is a word used to describe the police." ”

Lu Li: "Sometimes it is also used to describe the law. ”

Goofy: "The police use to uphold the law, and it's all essentially the same. ”

Zhou Lao: "Our CDC is also involved in many laws, the most famous is the Infectious Disease Law, and recently proposed to establish a biosafety regulation. ”

Gu Yanan: "We epidemic investigators are like detectives, and the phrase 'the sky net is restored but not leaked' that is usually used to describe the police is also applicable to our epidemic investigations. ”

It was 9:10 p.m. that night.

Lianhai Xinhua Apartment.

Gu Yanan's apartment building came down two middle-aged men in suits and leather shoes.

The two people were dressed exactly the same, both wearing dark suits, the same style of leather shoes, the same style of briefcase, and the words "so-and-so" law firm on the briefcase.

The elevator stopped on the 11th floor, and the two of them walked to the door of Chu Qingfeng's apartment and knocked lightly.

The door was opened from the inside, and Chu Qingfeng's face was serious.

"Hello Mr. Chu, the matter you entrusted to our law firm has been completed."

"Come in."

With Chu Qingfeng's permission, two middle-aged men entered the living room of Chu Qingfeng's apartment.

On the living room table, one of the middle-aged men took out two documents from his briefcase and handed them to Chu Qingfeng, explaining: "The paternity test results have come out, and this certificate has legal effect. ”

Chu Qingfeng flipped through the document and turned to the last page, with a number on it.

99.99%。

Proof that the two are directly related by blood.

Chu Qingfeng's face was dark, and he couldn't see his joy or anger.

A few minutes later, Chu Qingfeng said to the two middle-aged men opposite: "The appraisal certificate is put here, this matter cannot be known to anyone, especially my parents and my younger brother." ”

"Understood." The two middle-aged men who looked like lawyers agreed very respectfully.
