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

Doctor's office.

Gu Yanan is asking the attending doctor, Gu Jiashu, about Li Tianlong's condition.

"The typical symptoms of pneumonic plague have been given antibiotics, the infection is under control, and there should be no life-threatening symptoms."

"That's good, there are some questions to ask him." Gu Yanan breathed a sigh of relief.

"Haven't the close contacts been investigated? Our hospital has done throat swabs from close contact people, and no carriers have been found. Still haven't found out the flow survey problem? Need him to answer? He is now sober and should be able to answer questions. ”

In the case of the first-level response to the plague epidemic last time, because the workload of the CDC laboratory was very large, the Yersinia pestis preliminary screening experiment was shunted to major hospitals, as long as the initial test was done in the hospital, and the positive specimens would be sent to the CDC laboratory for review, so the hospital would also have the information of some patients and close contacts, and Gu Jiashu would have this question.

Gu Yanan: "The investigation is basically clear, it is not that the disease control wants to ask questions, but that there are other people who want to ask him questions, even if he escapes from this epidemic, it is estimated that there will be greater trouble waiting for him." ”

As soon as Gu Yanan's words fell, there was a knock on the door of the doctor's office.

Nan Hanfei and policeman Xiao Li stood at the door.

When the police come to the hospital, they do not go to the outpatient clinic, but to the doctor's office, that is, there is a case to be handled.

Thinking about what little sister Gu Yanan said just now, Gu Jiashu immediately reacted, "Officer Nan, are you here to find Li Tianlong?" ”

"Yes, someone reported that Li Tianlong was illegally carrying guns, and he was related to a transnational drug trafficking case, we want to question him, is it convenient now?"

"Convenient, the patient is awake, but he is now a pneumonic plague patient, and he is very contagious, so you can't ask face-to-face. But our isolation ward has a telephone visual system through which you can ask questions. ”

"Thank you, then please ask Dr. Gu to take us there."

"Okay, follow me." Gu Jiashu smiled, thinking that his future brother-in-law would call him brother in private, and he would only call him Doctor Gu when there were many people in the workplace, and this kid knew it very well.

Before leaving the doctor's office, Nan Hanfei looked at Gu Yanan and asked in a low voice, "Isn't Director Gu going with us?" Maybe you can ask for some useful news for your disease control. ”

"No, his whereabouts during the epidemic have been investigated by the relevant departments clearly, and the investigation is basically over, I have another food poisoning epidemic to deal with, you police and doctors are busy, and I have to go to the gastroenterology department to see the students with food poisoning."

"Okay, we'll get back in touch."

——

The First People's Hospital of Lianhai City, Department of Gastroenterology.

More than 30 students with food poisoning are being treated here.

Gao Fei has been following up on the situation here since the afternoon, and after meeting Gu Yanan, he began to report to her.

"Most of the poisoned students are in relatively stable condition, only two symptoms are more serious, and they are still being rescued, which is the case list I have compiled."

Gao Fei handed a stack of case sheets to Gu Yanan.

Gu Yanan roughly flipped through it.

I saw a familiar name in the case investigation form - Lin Ling.

Gu Yanan once heard her cousin Li Xinran mention that one of her roommates was named Lin Ling.

Looking at the other columns of the case questionnaire, the college is the School of Economics and Trade, so there is a good chance that this Lin Ling is the roommate of her cousin Li Xinran.

From the perspective of the colleges where the students are located, the colleges of economics and trade account for the majority.

I wonder how my cousin Li Xinran is doing?

Gu Yanan was worried, and Gao Fei said on the side, "Sister Yanan, I saw your cousin Li Xinran in the ward just now, but you can rest assured that she is fine, she is accompanying her roommate to the hospital." ”

"What ward is she in?"

"613, come with me."

Ward 613.

There are three hospital beds, and the people lying on each bed are the poisoned students sent from the university town of Dongcheng District this time.

Cousin Li Xinran was standing next to the hospital bed by the window, surrounded by two other girls, and there was a female classmate with a haggard face lying on the hospital bed, Li Xinran was asking some questions with concern next to her.

"Gladly." Gu Yanan shouted softly.

Li Xinran immediately heard that it was his cousin's voice, and turned back in surprise.

"Sister, why are you here?" As soon as the words came out, Li Xinran reacted, and his cousin must have come over at this time because of work.

There is such a big food poisoning incident in a college town, and my cousin, as a disease control staff, will definitely come to investigate.

"I'm going to do the flow survey, how are your classmates?" Gu Yanan approached the hospital bed and asked softly.

"The doctor hung up a drip, and Lin Ling was much better than when he first came to the hospital."

Lin Ling on the hospital bed was in a good state of mind, and when he saw Gu Yanan, he wanted to sit up and say hello, but because of his dizziness, he didn't sit up after trying twice.

Gu Yanan hurriedly made a gesture and motioned for her to continue lying on the bed.

Taking out Lin Ling's copy from the stack of flow investigation case sheets in his hand, Gu Yanan read it and asked a few additional questions.

"Did you eat anything other than in the cafeteria?

Do you think the food in the cafeteria is any different from before?

How long after eating does it start to feel sick?

What was the initial uncomfortable reaction? ”

In addition to Lin Ling, the other three accompanying roommates also expressed their opinions.

"This morning and noon, we only ate food from the cafeteria in our dormitory, but last night we ate souvenirs brought from home, and the whole dormitory shared the food." Li Xinran was the first to say.

Roommate Xiaoyu, "The food in the cafeteria we ate was the same as last year's, the same high oil and high salt, and many dishes almost had the same taste, so I think the chef must have not changed." ”

"After I ate, about 15 minutes later, I felt an itchy throat and a little pain, and then I felt dizzy, my stomach hurt, and I wanted to throw up." Lin Ling, who was lying on the hospital bed, spoke.

Roommate Jingjing, "I also have a little itchy throat, but it's not as serious as Lin Ling, and the doctor also prescribed me some oral medicine." ”

Jingjing took out a small packet of medicine from her pocket, it was some herbal tablets, and the name turned out to be licorice tablets, and if she had a sore throat, she would prescribe licorice tablets, which was also a symptomatic treatment.

Without asking for more clues, Gu Yanan instructed his cousin a few more words before leaving Ward 613 with Gao Fei.

Combined with the statements of his cousin Xinran and his roommates, Gu Yanan looked at the list of flow cases compiled by Gao Fei again.

All of the students who became ill became ill after lunch that day, and the onset time ranged from 15 minutes to several hours.

The food eaten at lunch has also been counted, and there is nothing unusual from the case flow chart alone.

"What does the attending doctor think?" Gu Yanan asked Gao Fei.

"The doctor said that until the cause of the poisoning is determined, only symptomatic treatment can be given, and from the current patient's blood picture and other test results, the possibility of bacterial and viral food poisoning can be preliminarily ruled out."
