Dongcheng District, Lianhai City, Xiaguang Road Primary School.

Gao Fei and Zhou Lao, who came in advance, as well as the staff of the district disease control, set up a temporary epidemic command team in the school infirmary.

After Gu Yanan arrived, Zhou Lao reported the current situation to her.

"Xiaguang Road Primary School is a full-time non-boarding primary school with two teaching buildings, six grades, 34 classes, and 105 teachers and 1,125 students.

The first case is Li Xiaofei, a 7-year-old student in class 3 of the first grade, who became ill on November 1 and went to the First People's Hospital of Lianhai City on November 5 for treatment, and was diagnosed with fever, and then there were cases in the class one after another, and the cumulative number of cases in the school as of today is 11 cases, affecting three classes, namely class 3 of the first grade, class 6 of the first grade and class 7 of the first grade.

The main manifestations of the sick students are fever, angina, and rash. The cases that have been detected have all been sent to the nearby Second People's Hospital for treatment, and there have been no serious deaths so far.

After preliminary investigation, it was found that Li Xiaofei's class 3 had taken a large class of physical education with classes 6 and 7, and the student who fell ill had close contact with the first case Li Xiaofei. ”

Gu Yanan: "What are the prevention and control measures? ”

"It has been recommended that schools allow students with the onset of the disease to isolate at home within one week from the date of onset of illness or have a certificate of resumption of classes issued by a hospital at or above the second level before resuming classes.

Let schools strengthen daily morning and afternoon inspections, detect fever and rash cases in a timely manner, and report and isolate and treat them in a timely manner once they are found.

The tableware touched by the sick student should be boiled and disinfected, and the used tables, chairs and sports equipment should be wiped and disinfected. ”

"What about in the classroom?"

Zhou Lao took Gu Yanan out of the school doctor's room, and when he arrived at the teaching building, he saw that the people from the district disease control were disinfecting the corridor of the teaching building with disinfectant.

Zhou Lao explained: "The classroom space is relatively spacious, the student seats are scattered, the classrooms are clean and bright, mostly north-south convection, the room is relatively ventilated, and the sanitation around the school is acceptable.

After the people who went to the district for disease control came this morning, they have asked the school to ventilate the classrooms, and recommended that they be at least three times a day for 15 minutes each time, and also carried out health education for the students in the school, and released the basic knowledge of scarlet fever prevention and control among the students' parents. ”

Gu Yanan: "Also, ask the class of the student who has the disease not to share the classroom with other classes. ”

"Okay."

In the afternoon of the same day.

Lianhai Center for Disease Control and Prevention, Emergency Office.

Gu Yanan received the test results from the laboratory.

Group A group B hemolytic streptococcus was detected in the blood sample of the first case, Li Xiaofei.

The pathogenic bacteria were also detected in the 3rd, 6th and 7th classes of the first grade of Xiaguang Road Primary School.

Three of the other 30 nasopharyngeal swab specimens from close contacts but who did not become ill were detected with group A betahemolytic streptococcus.

Gu Yanan immediately notified the school and quarantined the three close contacts who tested positive but did not become ill for observation and treatment.

On the morning of the second day, after going to work, the first thing Gu Yanan did was to call to inquire about the situation of Xiaguang Road Primary School.

Just when the emergency team thought that the epidemic at Xiaguang Road Primary School would be brought under control, Gao Fei received a personal phone call.

The call was from Gao Fei's girlfriend Zhang Xiao.

Zhang Xiao is a teacher at Xiaohonghua Kindergarten, a private kindergarten in Dongcheng District.

According to Zhang Xiao's reaction, when she entered the kindergarten this morning, two children in the kindergarten had red rashes, and the shape of the rash was different from the chickenpox that the kindergarten children often had.

Gao Fei thought of the scarlet fever epidemic that he was dealing with in the past two days, and Xiaohonghua Kindergarten was geographically close to Xiaguang Road Primary School, so it was very likely that there was contact between children and primary school students, could it be that they were infected?

This is the trend of the large-scale spread of the epidemic.

Gao Fei immediately reported this situation to Gu Yanan.

Gu Yanan also felt that something was wrong, and immediately notified the Dongcheng District Center for Disease Control and Prevention and went to Xiaohonghua Kindergarten to investigate.

——

Two hours later.

Dongcheng District Little Red Flower Kindergarten.

Gu Yanan, Gao Fei, and Section Chief Zhang of Dongcheng District Disease Control met in front of the gate of Xiaohonghua Kindergarten.

Gu Yanan showed his work card, and the principal and teachers of Xiaohonghua Kindergarten were very cooperative with the work.

Gao Fei's girlfriend Zhang Xiao took the CDC group to the kindergarten's infirmary, and two children with fever and rash symptoms were temporarily placed in the infirmary.

Gu Yanan stepped forward to check the symptoms of the two children.

Flushed skin, red rash, raised bumps around pores, sweat blisters, typical scarlet fever rash, a pale ring around the mouth, contrasting with the surrounding flushed skin, is typical of scarlet fever symptoms.

"Another outbreak of scarlet fever."

Gu Yanan asked one of the children who was sick, "When did you start feeling unwell?" ”

The little boy's milky voice said, "I'm not uncomfortable." ”

It's all fever and rash, how can it be comfortable? But looking at the little boy's mental state, he is okay and his temper is also very stubborn.

"When did you start showing little red dots?" Gu Yanan lowered his voice gently.

"I don't know, I'm not sick, I want to play with the children in the kindergarten."

"In addition to kindergarten and home, what other interesting places have you been to recently?"

"I've been to the playground." The little boy replied.

"I went to the supermarket, my mother bought me a set of Barbie dolls, I also went to an art class, I went to learn to draw." Another little girl replied.

"Have you ever been in contact with elementary school students? For example, the big brothers and sisters at Xiaguang Road Primary School next door. ”

"No, they don't like to play with us, they think we're small, and we don't play with them."

I couldn't get any more information from the children.

Gu Yanan knows that sporadic cases of scarlet fever are common, and that sporadic cases can cause clusters when they occur.

The initial source of infection is the first case, and the first case is likely to be infected with the pathogen from the surrounding environment, and it is very difficult to find the pathogen in the surrounding environment, so you can only find the first case and the close contacts around him, and then isolate and treat it, so as to stop the further spread of the epidemic.

Gu Yanan discussed the next prevention and control measures with Section Chief Zhang of the District Disease Control and Control, "Section Chief Zhang, you take the people of the District Disease Control and Control to conduct a physical examination of all the children in Xiaohonghua Kindergarten, and those with fever symptoms will be isolated for observation and treatment, and the close contacts of the two children who have become ill will be investigated for sampling and observation. ”

Section Chief Zhang: "I understand, all the measures and steps are the same as those of Xiaguang Road Primary School. ”

"Gao Fei, you notify Lu Li in the office, prepare an epidemic report, two consecutive scarlet fever epidemics, our disease control should make an early warning, it seems that our Lianhai City has entered a period of high incidence of scarlet fever, major childcare institutions and primary and secondary schools should do a good job of protective measures."

"Understood."
