Grandma Li has been staring at Gu Yanan's actions, watching her check Li Xiaofei's symptoms, collecting nasopharyngeal swabs for Xiaofei, a series of actions are completed very neatly, Grandma Li asked in a low voice on the side: "Is my Xiaofei really an infectious disease?" I heard that many students in his school are like Xiaofei, and they also have rashes, is it true? ”

Wang Xiaoxiao replied instead of Gu Yanan, "It's true, judging from Xiaofei's current symptoms, it is indeed scarlet fever, and the hospital has also done an antigen test, which can be confirmed." We CDC also have to do nucleic acid testing and strain culture, and do flow survey, now I ask you some basic questions, please cooperate with the answers. When did Dumbo start experiencing uncomfortable symptoms? For example, fever or loss of appetite. ”

Grandma Li thought for a while, "I started to have a fever about two days ago, but before that, that is, four days ago, Xiao Fei said that he didn't want to eat, and I thought it was nothing at the time, it should just be a cold, so I sent him to school, and on the second day, the fever was more severe, and his homeroom teacher informed me to take Xiao Fei home."

On the way back, I took Xiaofei to a community hospital near my home, and after the doctor's examination, he also said that he had a cold, and prescribed antipyretics.

After a good night's sleep, I went to school, but I found that Xiao Fei began to have a rash at school, and the teacher told me to take Xiao Fei home.

I went home and stayed overnight, on the second day, Xiaofei had a high fever that did not go away, I felt that something was wrong and took him to the First People's Hospital, and the doctor said that he had sepsis and needed to be hospitalized. ”

Gu Yanan summarized Grandma Li's words and compared them with the flow data sent by the district disease control and control, and determined that Li Xiaofei was the first case of the scarlet fever epidemic in Xiaguang Road Primary School.

Li Xiaofei was the initial source of infection in this outbreak.

Gu Yanan asked: "What special places did Li Xiaofei go to before he lost his appetite?" Who have you come into contact with? ”

Grandma Li: "Xiaofei is usually taken by me and his grandfather, his father and his stepmother don't care at all, usually except for going to school, they are at home, 4 days ago...... Last weekend, my grandfather and I took him to the supermarket, and then I went to the park near my house for a long time, and I didn't meet any strangers. ”

Gu Yanan knows that the pathogen that causes scarlet fever is group A beta-hemolytic streptococcus, also known as Streptococcus pyogenes, which is widely present in the external environment and sometimes latent in the human respiratory system, causing patients to develop illness when people's immunity is reduced.

Li Xiaofei will become ill, which may be infected with pyogenic infanticoccus from the external environment, or it may be carried by himself, and the immunity is reduced due to recent weather changes.

However, in either case, Li Xiaofei is certain that he transmitted the scarlet fever pathogen to the students in his class and school, and the next step is to prevent other sick elementary school students from spreading scarlet fever.

Gu Yanan finished the flow survey, carried the sampling box out of Li Xiaofei's ward, and exchanged information with his brother Gu Jiashu in the corridor.

"Brother, I see that Li Xiaofei's medical record file records that he has already used antibiotics, and now it is no problem to sample him for nucleic acid testing, but it will be difficult to isolate the strain, and the hospital should have kept his sample before using antibiotics, right?"

"Keep it, the sample is in the laboratory department of the hospital, I will call them later and give you the blood sample."

Xiao Chu and Wang Xiaoxiao followed behind Gu Yanan, and were about to go to the hospital laboratory with Gu Yanan to get Li Xiaofei's sample before, when suddenly, a beautiful woman came around the corner of the hospital corridor.

Wang Xiaoxiao's eyes widened, she knew this woman, it was the big star Li Jiahui.

Li Jiahui's eyes were always on Gu Jiashu, and after smiling and nodding to greet him, she found Gu Yanan and his party beside Gu Jiashu.

Li Jiahui greeted Gu Yanan again, "Hello Director Gu, I didn't expect to meet again, this time there is another epidemic in the hospital?" ”

"Well, you're coming to my brother?"

Li Jiahui smiled with shyness, "Yes, your brother is very busy with work, I'll send him some fruit." ”

Everyone present seemed to have an understanding, Li Jiahui hurriedly changed the topic and asked Chu Qinggeng, who was following Gu Yanan, "Xiao Chu, are you still used to working in disease control?" ”

"Sister Jiahui, I'm fine, Director Gu takes good care of me."

Li Jiahui said to Gu Yanan, "Xiao Chu's family and my family are world friends, I watched Xiao Chu grow up, he is a good boy, and now he has Yanan to take care of him at work, so it won't be hard." ”

In just a few words, Li Jiahui's address to Gu Yanan has changed from Director Gu to Yanan.

"Xiao Chu is my colleague and team member, of course I will take care of him. You and my brother talk first, and I'll take them to the laboratory department and don't bother you. ”

From the infectious disease department to the laboratory department on the second floor, Wang Xiaoxiao came to Gu Yanan's side with a gossip on his face, and whispered: "Sister Yanan, the gossip news on the Internet is true, your brother is really dating the big star Li Jiahui?" ”

"Don't gossip, I don't know what's going on."

"Sister Yanan, didn't Doctor Gu mention it to you? Your brother and sister have always had a good relationship. ”

Gu Yanan didn't talk, thinking to himself, even if the matter between my brother and the big star Li Jiahui is as true as the scandal uploaded on the Internet, it is also a recent thing. The elder brother didn't tell her about having a girlfriend, and the two may not have developed to the extent of establishing a boyfriend-friend relationship. But looking at Li Jiahui's look towards her brother just now, there must be something between the two. This matter, after the investigation of the epidemic is over, I have to ask my brother well.

Gu Yanan didn't speak, Wang Xiaoxiao asked Xiao Chu beside him again, "Just now Li Jiahui said that the two of you are world friends, so you should know her situation, right?" ”

Xiao Chu glanced at Gu Yanan before answering Wang Xiaoxiao, "Sister Jiahui doesn't seem to have a boyfriend, but I heard her younger brother Li Yixuan say that someone has been pursuing her." ”

"There must be many suitors for big stars, is there Dr. Gu in it?"

"Sister Jiahui and Dr. Gu should have known each other last time Li Yixuan was infected with the monkeypox virus, and Dr. Gu should not be one of her many suitors, but I don't know what happened after they met."

"But I look at the situation just now, Li Jiahui obviously likes our Doctor Gu very much."

Xiao Chu: "I heard Li Yixuan say that Sister Jiahui seems to often take the initiative to contact Dr. Gu, but Sister Jiahui has many suitors, one of whom is particularly close, and her family background is not bad. ”

"Xiao Chu, you are so familiar with the Li family, you must know a lot of news, who is that suitor? Are Li Jiahui and Dr. Gu like the rumors on the Internet? And who is chasing and who is ......" Wang Xiaoxiao asked too many questions.

Xiao Chu's face was embarrassed, he was not a person who liked to reveal his friends' privacy, and what he said just now was more like saying it to Gu Yanan, and he was a little embarrassed in the face of Wang Xiaoxiao's successive questions.

Gu Yanan coughed deliberately and interrupted the chat between the two, "The gossip discussion should be stopped, hurry up and get down to business, take Li Xiaofei's blood sample from the laboratory department, and talk to Section Chief Li after returning to the disease control laboratory, do a quick test first, and then slowly do the isolation and culture of the strain after getting a certain result." ”

Wang Xiaoxiao was surprised, "Sister Yanan, aren't you going back with us?" ”

"You and Xiao Chu go back first, and I'll go to Xiaguang Road Primary School to see how the school's prevention and control measures are doing."
