The next morning.

Lianhai Center for Disease Control and Prevention, Conference Hall on the 7th Floor of the Center Building.

A tabletop exercise on the cholera outbreak begins.

The conference hall was crowded with people.

Gu Yanan and several heads of departments who mainly participated in the handling of the epidemic sat around the central round table.

In the center of the round table, there is an electronic projector, and digital images and pictures are projected in the air, a hazy and real beauty.

All participants circled around the round table.

Lu Li, Wang Xiaoxiao, Zhou Jie, Gao Fei and others sat in a circle behind Gu Yanan.

Gu Qingcen sat beside Gu Yanan.

Director Yang of the center sat opposite Gu Yanan.

Other CDC colleagues and interns sat in the back rows.

On the central screen is the headline "2019 Lianhai City Cholera Epidemic Emergency Response Tabletop Exercise".

Tabletop deduction begins.

Gu Yanan presided, "Our purpose of this exercise is mainly three: first, to test the mastery of the working procedures and technical requirements stipulated in the "Cholera Prevention and Control Manual", "Lianhai City Cholera Epidemic Emergency Response Technical Plan", "Technical Specifications for Disinfection of Epidemic Sources" and other documents.

Second, we need to further strengthen the epidemic handling process and improve the response capacity of the emergency response team. Especially in personal protection, on-site flow adjustment, specimen collection, epidemic point and epidemic area sanitization publicity and education.

Third, establish a coordination and cooperation mechanism between different departments and personnel to strengthen emergency awareness and emergency management capabilities. ”

After speaking, Gu Yanan's hand moved slightly, and the slide went to the next one.

An electronic map of Lianhai City appears.

There is also text next to the map, which is a case study of tabletop deduction.

Gu Yanan pointed to a certain location on the electronic map with a red laser pointer, "The case of this desktop deduction is to assume that a farmer in a village in Punan Town, our city, had severe diarrhea after attending a banquet, and was successively diagnosed and treated in the village clinic and the city's First People's Hospital.

The First People's Hospital of Shanghai detected Vibrio cholerae O139 in the feces of the patients, and immediately reported to the district and municipal centers for disease control and prevention, and the two levels of centers for disease control and prevention quickly went to the scene for investigation and disposal. ”

The slides transform again.

"Here's scenario 1: Outbreak detection and reporting.

Specifically, at 11:10 a.m. on May 1, 2019, the emergency response office of the Municipal Center for Disease Control and Prevention received a telephone report from the First People's Hospital of the city, saying that the hospital admitted one case of diarrhea patient with vomiting and painless diarrhea symptoms, and colloidal gold was positive for Vibrio cholerae O139, and was preliminarily diagnosed as a suspected case of cholera, and made a direct report online.

At present, the patient has been isolated and treated, and now needs to be investigated and dealt with by the CDC. ”

After Gu Yanan introduced the first scene, he looked around, and then asked two questions, "In this scene, when the epidemic duty officer receives the epidemic report, what information do they specifically ask?" What needs to be done?

These two problems are usually dealt with by the emergency office, Wang Xiaoxiao will talk about it. ”

Wang Xiaoxiao stood up from the back seat and said according to the previously arranged rhetoric, "The information asked when receiving the epidemic report includes: the basic information of the patient, mainly age, gender, occupation and home address, inpatient hospital, clinical symptoms and signs, etc.; the department, medical staff, disinfection and other hospital diagnosis and treatment processes of the patient; There is also the contact details of the hospital contact.

After understanding the above information, the measures that need to be taken are mainly to report to the head of the department and the leader on duty, if it is me, I must report to the director of our emergency office; Make emergency preparations according to the requirements of the leader on duty.

Emergency preparedness includes the preparation of personnel, materials and materials.

The personnel preparation is mainly professionals in epidemiology, pathogenic microbiology, disinfection, etc., and to be more specific, the personnel of various relevant departments of our CDC.

The materials and material preparation are mainly items, record sheets and protective equipment for on-site transfer, including cholera case investigation forms, close contact registration forms, specimen collection record forms, cameras, protective clothing and other personal protective equipment, sanitizing equipment and medicines.

These items and materials are prepared by the relevant departments.

According to the daily work requirements of our CDC, these things have emergency reserves.

That's my answer to both questions. ”

After Wang Xiaoxiao finished speaking, Gu Yanan controlled the slide to the next one.

Gu Yanan: "Next is Scenario 2: Field Epidemiological Investigation.

After receiving the report of the suspected cholera epidemic, the CDC immediately organized emergency response personnel to arrive at the hospital at 11:30 for verification, investigation and handling.

These on-site investigations are handled by our Emergency Office.

Lu Li, let's talk about the question in this scenario: What kind of work needs to be carried out after the CDC emergency team arrives at the scene? ”

Lu Li sat behind Gu Yanan, and when he heard Gu Yanan's roll call, he also began to say according to the steps rehearsed in the emergency office yesterday: "In response to the cholera epidemic, the work that the disease control team should carry out after arriving at the hospital includes: checking medical records, asking the first doctor, and verifying the diagnosis.

According to the cholera case questionnaire, on-site investigation was carried out on suspected patients, including the basic information and clinical manifestations of the patients, and detailed information about the patient's diet, drinking water, medical history, and close contacts in the 5 days before the onset of the disease.

Stool samples were collected from patients, as well as suspected food and water for cholera pathogens.

Instruct hospitals to carry out in-hospital disinfection and patient isolation. Of course, the sanitizing aspect is helped by colleagues in the sanitization section. ”

After Lu Li finished speaking, he sat back in his seat directly, and Gu Yanan continued to scene two.

"After on-site investigation, the emergency team sorted out the results of the investigation: Case Li, male, 38 years old, farmer, home address is a village in Punan Town, Dongcheng District, Lianhai City, self-reported that he began to have diarrhea and vomiting symptoms at 23 o'clock on April 29, and his stool was yellow and watery, and the amount was large.

Since 10 a.m. on April 30, he was treated at a clinic in a village in Punan Town, and his symptoms did not improve, and he had diarrhea about 10 times a day.

At 20 o'clock in the evening of April 30, he was transferred by taxi to the Department of Infectious Diseases of the First People's Hospital of the city for treatment.

Poor mental health at admission with moderate dehydration.

At 11:10 a.m. on May 1, the laboratory department of the hospital quickly tested positive for Vibrio cholerae O139.

The patient self-reported that except for attending the wedding banquet at noon on April 29, he had no history of eating out or suspected dietary exposure in the 7 days before the onset of symptoms, and had no history of contact with similar cases. ”

After summarizing scene 2, Gu Yanan, as the host of the deduction, controlled the slide to enter scene 3.

Gu Yanan: "The following is scenario 3: At 9 a.m. on May 3, the district CDC laboratory reported that the fecal specimen culture result collected by the patient on May 1 was positive for Vibrio cholerae O139, which was confirmed by the Municipal Disease Control and Prevention Laboratory.

The district CDC immediately revised the suspected cholera case to a confirmed cholera case.

At 10 o'clock on the same day, the District Health Commission instructed the CDC to conduct a direct online report of the emergency, and at the same time reported the epidemic to the Municipal Health Commission, the Emergency Office of the District People's Government and the deputy head in charge for the first time, and suggested that the district government start an emergency response.

After receiving the recommendation, the district government immediately activated the emergency response. ”
