Gu Qingcen just listened and didn't express an opinion.

Wang Xiaoxiao turned her head to look at Lu Li, wanting to ask Lu Li's opinion on this matter.

Lu Li was answering the office phone on the desk, listening to the phone with a slightly frowning and serious look, and when he finished answering the phone, Wang Xiaoxiao hadn't asked any questions, Lu Li couldn't wait to report to Gu Yanan, "Sister Yanan, I just received a call from the school doctor in the Eastern University Town, he said that there was a suspected anthrax case on their campus, and the patient had been sent to the First People's Hospital of Lianhai City. I have the patient's name here, but no more news is available. ”

Anthrax outbreak? If it is confirmed to be true, it is very serious, and there has been no case of anthrax in Lianhai City for many years.

Gu Yanan immediately opened the epidemic system on the desk computer, and there was no report of suspected anthrax cases in it, which means that the First People's Hospital has not yet made a diagnosis, I don't know if the patient has not arrived at the hospital, or the doctor has not made a diagnosis.

Gu Yanan called his brother Gu Jiashu.

"Brother, is your hospital receiving any suspected anthrax cases now?"

"No, why do you ask? If there is a suspected case of anthrax, this is a big deal, and of course I will notify you of the CDC as soon as possible. ”

Gu Yanan told his brother the content of the epidemic call he had just received, "The school doctor in the university town of Dongcheng District called and said that there was a suspected anthrax case, and the patient was being sent to your hospital.

Brother, you can help me check and see which department this patient is treating now, and I must control it in time to avoid infecting others. ”

"Okay, you tell me the patient's information, and I'll look it up from the hospital computer from now on."

Lu Li put the information recorded when answering the phone on Gu Yanan's desk, and Gu Yanan narrated the information one by one, "Zhang Yongsheng, male, 42 years old, is a chef in the cafeteria of the University Town in the Eastern District, according to the symptoms described by the school doctor, Zhang Yongsheng's right arm is swollen, and there is a black eschar on his arm. ”

A few seconds after Gu Yanan finished speaking, Gu Jiashu responded, "I found it, Zhang Yongsheng is now in the dermatology department of our hospital, I will go to see the situation immediately, if it is really a suspected anthrax case, I will transfer him from the dermatology department to the infection department." ”

A few minutes later, Gu Jiashu called again.

"Little sister, I am now in front of Zhang Yongsheng in the dermatology department, judging from his clinical symptoms, it can be determined that he is a clinical anthrax case, and he has a history of contact with raw mutton, and I am now preparing to transfer him to the isolation ward of the infection department."

"Okay, I know, I'll send someone from the disease control over now."

After ending the call with his brother Gu Jiashu, Gu Yanan began to arrange tasks for the disease control team.

Gu Yanan and Gu Qingcen went to the hospital to see Zhang Yongsheng's condition.

Zhou Lao and Gao Fei went to the university town in the Eastern District to investigate the working environment of Zhang Yongsheng.

Lu Li and Wang Xiaoxiao went to the community where Zhang Yongsheng lived to investigate where he usually lived.

——

Lianhai First People's Hospital, Department of Infectious Diseases.

Chef Zhang Yongsheng's ward.

Zhang Yongsheng, who was lying on the hospital bed, looked haggard, and his face was even more nervous when he saw Gu Yanan and Gu Qingcen standing on the hospital bed wearing bioprotective clothing.

Gu Jiashu, the attending doctor, explained to Gu Yanan, "The patient's herpes fluid was examined by the laboratory department of our hospital, and a large number of brevis rod-shaped bacteria were found to be flush at both ends, which are morphologically consistent with Bacillus anthracis. ”

"What about serological or genetic testing?"

"I can't do it, I don't have a reagent stockpile."

"Oh, then take another sample of the patient's blood and herpes fluid, and bring it back to the CDC laboratory in a moment to do the isolation and culture of serum, genes, and bacteria."

Gu Qingcen personally collected the herpes fluid on the patient's Zhang Yongsheng's arm, drew a tube of blood from him, and put it in the sampling box.

Gu Yanan began to ask Zhang Yongsheng about his epidemiological history.

"When did the blisters on your arms start to appear? Or when did you start feeling sick? ”

Zhang Yongsheng thought for a while and replied exactly, "When I got up in the morning three days ago, I felt a little itchy on my arm, and my arm was a little swollen at that time, and I had a blister on my arm after cooking in the cafeteria at noon.

On the second day, the blisters broke and started to scab over, and I didn't care about it at the time.

When I woke up this morning, the scab turned hard black, and my whole arm was very swollen. ”

"Did you come into contact with anything special three days ago? For example, sick and dead cattle and sheep? Or is it the fur of an animal? Or have you touched raw beef and mutton directly with your hands while cooking? ”

"I usually cook with my hands directly touching the raw meat, and I haven't gotten sick for more than ten years.

Oh, one thing, I remember, three days ago we had a new batch of frozen lamb in our cafeteria, and I was in charge of handling it. ”

"Where did you buy the lamb from? Is there an invoice or quarantine certificate? ”

Zhang Yongsheng shook his head, "I am only responsible for cooking, as for the purchase of various ingredients, the boss of the contracted canteen is responsible for it, I am just a part-time worker." ”

Gu Yanan wanted to continue to ask who the owner of the canteen was, but suddenly, there was a knock on the door outside the ward, and a young doctor reported the situation to Gu Jiashu, "Director, a critically ill patient was transferred from Yuntai County Hospital, with severe sepsis, and needs to be admitted to our infection ward."

Also, the college student who came with Zhang Yongsheng in the ambulance was the patient who was admitted to the gastroenterology department for peritonitis, and the director of the gastroenterology department heard that a case of anthrax was diagnosed on our side, and he suspected that the college student was also infected, so he applied to transfer the college student to our infectious disease department. ”

There are a lot of things that Gu Jiashu needs to deal with.

Gu Jiashu greeted Gu Yanan, "You continue to ask about the epidemiological history of the patient here, and I will deal with other things." ”

"Doctor Gu, wait a minute." Gu Yanan called out to his brother Gu Jiashu, "That college student suspected of being infected with anthrax, after settling in the ward, we will have to go over and take a look." ”

"Understood, I'll go and arrange the ward for an examination first."

After Gu Jiashu left the ward, Gu Yanan continued to ask Zhang Yongsheng about the source of mutton.

Zhang Yongsheng: "I have to ask the owner of our canteen for the specific situation, but I heard the boss complain about the recent increase in the price of mutton, and he personally ran several ranches that produce mutton, and I seem to have heard that the boss bought a large number of frozen mutton from a ranch in Yuntai County at a low price." ”

Gu Yanan analyzed in his heart, judging from the time of Zhang Yongsheng's illness, the source of infection is likely to be the new batch of mutton three days ago, and the mutton came from a pasture in Yuntai County, Lianhai City has not found a local anthrax case since the epidemic monitoring record, and Yuntai County is not the natural source of anthrax, where did the Bacillus anthracis in this outbreak come from?

Gu Yanan was thinking about various possibilities, when a young doctor from the infectious disease department ran over to inform Gu Yanan, "Director Gu, the director of our department asked me to tell you that gram-positive bacteria were detected in the blood smear of that college student, which is suspected to be Bacillus anthracis. ”

Another suspected case of anthrax, and the patient is a student in the Eastern University Town, and the chef Zhang Yongsheng is the chef in the cafeteria of the Eastern University Town, two cases in a row, and perhaps more cases in the university town.

Gu Yanan immediately notified Zhou Lao and Gao Fei, who were conducting an investigation in the university town in the eastern district, and asked them to focus on inspecting the school cafeteria where Zhang Yongsheng worked, as well as the dormitory of the class where the sick college student was located, and the surrounding population, and conduct rapid serological tests on teachers and students to see if anyone was infected with anthrax.
