Infectious Diseases Department, the ward of a college student suspected of being infected with anthrax.

Yoshiki Gu is examining college students.

After initial treatment, the college student was still in a coma when he was brought to the hospital, but now he has woken up.

Gu Jiashu knew that the people from the CDC were anxious to ask about the epidemiological history, so he let Gu Yanan and Gu Qingcen enter the ward with a look.

Gu Jiashu: "Combined with laboratory tests and clinical symptoms, the patient should have been infected with Bacillus anthracis through the digestive tract, and the symptoms are typical of intestinal anthrax. ”

The chef Zhang Yongsheng just now has cutaneous anthrax, and now college students are intestinal anthrax, and two of the three clinical types of anthrax fever have appeared, and the intestinal anthrax of college students has already shown signs of secondary septicemia anthrax.

While the college student patient came to his senses, Gu Yanan began to ask, "When did you start feeling unwell?" ”

"I have always been fine, I can eat, drink and sleep, but when I was eating at noon today, I suddenly felt a terrible stomach ache and dizziness, and then I didn't have any impression, and when I woke up, I lay here."

Gu Yanan thought to himself that the incubation period of intestinal anthrax of acute gastroenteritis type is generally 12~18 hours, and according to the onset time of the patient, then the time when he ingested Bacillus anthracis should be the night before.

Gu Yanan asked, "What did you eat yesterday?" Especially yesterday evening into the night. ”

"Yesterday I ate in the school cafeteria, I ate porridge steamed buns in the morning, and a small amount of pickles, a bowl of rice noodles at noon, and a small pie in the evening, but we went to the snack street next to the university town at about 8 o'clock in the evening to eat skewers."

"Have you ever eaten lamb from the school cafeteria?"

"Nope."

"What's on the skewers for a late-night snack?"

"Lamb kebabs, grilled small yellow croaker skewers, some grilled vegetables or something."

And mutton! Moreover, the lamb in the barbecue is often undercooked, which is the most prone to problems.

"Do you remember the place where you ate the barbecue and the name of the restaurant?"

"Remember, the barbecue stall at the east lane of the food street next to the university town."

This barbecue stand is the focus of the survey.

Gu Yanan wants to transfer manpower, call Lu Li first, Lu Li and Wang Xiaoxiao were arranged by Gu Yanan to go to chef Liu Yongsheng's house for a flow investigation, according to the time, the two should have almost checked by now.

Answering the phone, Lu Li first reported to Gu Yanan, "Sister Yanan, there is nothing abnormal in Zhang Yongsheng's family, his family is currently in good health, there is no animal fur at home, there is raw pork in the refrigerator, we have collected samples and are preparing to send them back to the CDC laboratory." ”

"Okay, after sending the samples back to the lab, you can go to the food street next to the university town in the East Side, there is a shop called Dongxiangkou barbecue stall, and take samples inside, especially to check their mutton products."

After the task was arranged, Gu Yanan and Gu Qingcen's transfer to the hospital was basically over, Gu Yanan decided to go to the university town to help, Zhou Lao and Gao Fei had a large number of teachers and students there, and the two of them plus a few people from the district disease control were still too busy.

Before going to the university town, the samples collected from the hospital had to be sent back to the CDC laboratory, and Gu Yanan wanted to ask a small nurse from the infectious disease department to help send them, but Gu Qingcen took the initiative to ask to go back to the CDC laboratory and rush to the university town to meet them after sending the samples, Gu Yanan didn't think much about it, so he agreed.

——

Lianhai City, University Town in the Eastern District.

The canteen where the anthrax outbreak occurred was temporarily closed, and all teachers and students in the school underwent physical examinations.

The Center for Disease Control and Prevention has brought in a large number of colloidal gold reagents for the detection of Bacillus anthracis, which are used to quickly detect Bacillus anthracis in the blood, and the results can be obtained in 5 minutes.

By the time Gu Yanan arrived at the university town in the eastern district, Zhou Lao and Gao Fei organized disease control personnel to test more than half of the teachers and students in the school, and found 6 more cases of anthrax infection, but the clinical symptoms were not obvious, and there were IgM antibodies in the blood, which indicated that they had recently been infected with Bacillus anthracis.

Multiple cases of anthrax have been detected among students, which has caused panic throughout the college town.

When the anthrax outbreak broke out, Gu Yanan reported to Director Yang of the Center for Disease Control and Prevention, and at the same time suggested that the city activate the emergency plan and set up an epidemic control team composed of various departments throughout the city.

The eastern university town was designated as an epidemic site, and colleagues from the sanitizing department of the CDC disinfected the environment in the university town, and Gu Yanan contacted the vaccine manufacturer to urgently transfer anthrax vaccine to vaccinate all teachers and students in the school.

The owner of the school cafeteria was controlled by the police, and Gu Yanan went to interrogate.

The owner of the canteen is a lean old man in his 50s, who is controlled by the police in the office area on the top floor of the canteen.

Before questioning the canteen owner, Gu Yanan had already obtained the test results of the canteen mutton samples from the CDC laboratory.

Bacillus anthracis was detected in frozen raw lamb, and Bacillus anthracis was not detected in the finished cabbage stew made from this batch of mutton.

Gu Yanan took the test report and asked the canteen owner, "Where did you buy this batch of mutton?" ”

The canteen owner was already frightened by the situation in front of him.

A large number of police officers surrounded the school and the cafeteria, the cordon was pulled up, disease control personnel in bioprotective suits were busy in the crowd, and doctors kept picking up students from the school.

The owner of the canteen who was under control answered all questions, "This batch of mutton was bought from Yuntai Ranch in Yuntai County, and the owner of that ranch said that it was freshly killed mutton, but when I bought it, it was all frozen, and I don't know if it was freshly killed." ”

"Did he provide a quarantine certificate at that time?"

The canteen owner shook his head, "I didn't ask, the ranch owner didn't provide it, the price of this batch of meat is lower than the market price, I thought it was because I bought it directly from the ranch, but now I think that there must be something wrong with their mutton, and I was also deceived." ”

The cafeteria owner was busy distancing himself from the relationship.

Gu Yanan felt very familiar with the Yuntai Ranch in Yuntai County mentioned by the old canteen owner, and seemed to have heard it somewhere.

In the ward of the Infectious Diseases Department of the First People's Hospital, the young doctor reported the situation to Gu Jiashu, including the mention of a patient transferred from Yuntai County, when Gu Yanan was looking at the case file of the sick college student, and glanced at his medical record file by the way, the person's place of work was Yuntai Ranch in Yuntai County.

There were not so many coincidences, Gu Yanan had a hunch that the patient who was sent to the city hospital from Yuntai Ranch was in condition.

Gu Yanan suddenly thought of this question during the questioning of the canteen owner, so he called his brother Gu Jiashu directly.

"Brother, the patient who was transferred from Yuntai County to your infectious disease department in the morning is the same patient who works at Yuntai Ranch in Yuntai County, do you remember?"

"I remember, his name is Wang Likun, he is the rancher of Yuntai Ranch, and he has a serious lung infection with systemic sepsis."

"Did he get anthrax too?"

Gu Jiashu was slightly stunned, they used broad-spectrum antibiotics for Wang Likun's sepsis, and the infection has been controlled, but the specific pathogen laboratory is still in the process of testing.

Gu Jiashu: "I'll ask the laboratory to check for Bacillus anthracis, and I'll tell you as soon as I get the results." ”

While waiting for the test results from the hospital, Gu Yanan asked the canteen owner a few more questions.

Gu Yanan felt that for this anthrax epidemic, it was close to its real source of infection.
