"I also know that I will do a lot, but the two patients are children, usually live together, and the two of them develop at the same time, which is a cluster case, and I am worried that if the pathogen is not found in time, it will cause the spread of the epidemic, so I can only trouble you." Gu Yanan often has to coordinate the relationship between the various departments.

Section Chief Li just complained, and finally agreed unconditionally, "The specimen is sent, I will get the results as soon as possible, since it is viral encephalitis, cerebrospinal fluid must be the most important." ”

"Okay, cerebrospinal fluid and other bodily fluid specimens are on their way to the lab."

After contacting the laboratory, Gu Yanan glanced at the time, and there were still more than 4 hours left for the video conference in the afternoon, and he could go to the people's hospital and the patient's home to do the flow survey.

Gu Yanan assigned tasks to the emergency response team.

"Right now, time is tight, so we're going to split up.

Zhou Lao and Gao Fei went to the First People's Hospital, questioned the two young patients with the case investigation form, and sampled and circulated the family members who accompanied them.

Lu Li and Xiao Chu went to the patient's house.

Xiaoxiao stayed in the office and inquired from the epidemic system whether Lianhai City had recently reported cases of encephalitis of unknown cause.

Everyone hurry up and rush back before the video conference in the afternoon, and finally say that we must be busy and meticulous in the process of flow survey, and do not miss the details. ”

——

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

The ward of patients with encephalitis of unknown cause, Li Tianyi and Li Tianming.

The younger brother Li Tianming is in a comatose state, and the elder brother Li Tianyi is in a slightly better state and can speak.

Zhou Lao and Gao Fei, accompanied by Gu Jiashu, questioned their brother Li Tianyi and Grandma Li.

Zhou Lao was in charge of the questioning, and Gao Fei followed to fill out the case investigation form.

Zhou Lao asked Li Tianyi, "How are you feeling now?" Can you answer my question? ”

Li Tianyi glanced at Grandma Li, who was accompanying him, and nodded.

"When did you start feeling sick lately?"

Li Tianyi blinked, as if recalling, "I have a cold, and my brother has a cold too." ”

The child answered the question, and Lu Li turned the target of the inquiry to Grandma Li, who was accompanying him.

"Have your two grandchildren caught a cold recently?"

Grandma Li: "Yes, I had a cold some time ago, when both children were coughing and sneezing and had a fever, I took them to a community hospital near my home, the doctor checked the blood and said it might be a viral cold, and prescribed medicine, and the fever subsided after three days, but I kept coughing."

I also asked the old Chinese medicine doctor in the village to regulate the body of the two children, and the children were much better in the two days after taking Chinese medicine, and they did not cough.

But somehow, the night before yesterday the child suddenly began to talk nonsense, and then he began to tremble, cramp, foam at the mouth, and his whole face was purple.

Doctor, you said my grandson was fine, why did this suddenly happen? ”

Cold symptoms and encephalitis symptoms are very different, and it can be inferred from the question just now that the two children had cold symptoms for three days before they developed encephalitis symptoms.

Is this unexplained encephalitis a sequelae of a cold? Is it caused by the same pathogen between the two?

Influenza viruses and respiratory syncytial virus can cause upper respiratory tract symptoms but rarely cause encephalitis.

Zhou Lao also thought that it might be other viruses that can cause both upper respiratory symptoms and encephalitis.

Mr. Zhou asked Grandma Li, "Have your two little grandsons been exposed to wild animals recently?" Chickens, pigeons or mice? Or have you been to a particular place? What's different from usual? ”

Grandma Li shook her head very surely, "No, there is a final exam recently, the two children are in the second grade, they are very nervous about studying, and they don't have time to go out to play. The children are very well-behaved, usually except for school is at home, and the things you said have no chance to touch at all. ”

School?!

Zhou Lao sensitively found that if the diseases of Li Tianyi and Li Tianming in front of him were contagious, then his classmates were likely to have similar symptoms.

Zhou Lao asked Li Tianyi, who was lying on the bed, "Are there any of your classmates who are as sick as you?" ”

"Yes, several people who have caught a cold have also taken leave."

Zhou Lao felt that something was wrong, and after finishing the flow in the ward, he left the ward and immediately called Gu Yanan.

"Director Gu, I found some clues during the investigation of the ward, the two patients were at the school when they became ill, and I was worried that the students in the school would be infected."

In the emergency office, Gu Yanan and Wang Xiaoxiao are sorting out the information on the information system about recent cases of encephalitis of unknown cause.

Hearing the information reported by Zhou Lao from the People's Hospital, Gu Yanan was not surprised, because she had already thought that the students Li Tianyi and Li Tianming were students in the second grade of primary school, and they must be in school at ordinary times, and the initial onset should also be at school, so when Zhou Laoyi left the emergency office, she first checked the situation of the primary school where Li Tianyi and his brothers studied on the information system, and found no cases of encephalitis of unknown cause.

Gu Yanan: "According to the big YQ network, so far, no cases of encephalitis of unknown cause have been found in the school where Li Tianyi's brothers studied. Old Zhou, you and Gao Fei will come back first. ”

Zhou Lao breathed a sigh of relief, "It's good if you don't, the original source of infection may not be in school." Grandma Li, a family member, looked frail, but did not show corresponding symptoms, and it seems that the unexplained encephalitis this time is not very contagious. ”

——

The southern suburb of Lianhai City, an urban village.

Grandma Lee's home.

Lu Li and Xiao Chu drove the live stream shunting car and parked in the small alley downstairs of Grandma Li's house.

Grandma Lee's home is on the second floor of a dilapidated six-story building.

Grandpa Li got the news that the CDC was going to go to the house for investigation, so he rushed back from the hospital.

Grandpa Li opened the door, the house with 2 bedrooms and 1 living room, although the furniture is old, it is very clean and the layout is very warm.

Grandpa Li pointed to a bedroom on the north side and introduced Lu Li, "The two children usually live in this room, doing homework and sleeping in it, and they usually eat with our old couple in the living room, and the two of them occasionally go to the kitchen to find water to drink." ”

Lu Li and Xiao Chu entered the bedroom on the north side one after the other.

In the bedroom, there is a bunk bed that can sleep two children, and the quilt on the bed is neatly folded.

There are two desks next to the bed, on which there are books and lamps, and the books are neat.

In the corner on the other side of the table is a toy basket with toys that boys like to play with, such as cars and basketballs.

There is a small wardrobe next to the toy basket.

Nothing else, no greenery, no pets.

Out of the bedroom, Lu Li took a turn in the living room again, and found that the furnishings in the living room were also very simple, with a sofa TV and a dining table.

Adjacent to the living room is a small balcony with 4 pots of flowers, common spider plants and rhododendrons.

The rhododendrons have a few buds on them, and they have not yet opened.

There are screens on the balcony windows, which can keep mosquitoes out well.
