Gu Qingcen, who was sitting next to Gu Yanan, began to introduce calmly, "There are generally three conditions for judging the end of the cholera epidemic: the patient has been discharged according to the discharge criteria; Vibrio cholerae was not found in two consecutive fecal tests of all persons in contact with the patient; No new cases have been detected at the site for five consecutive days.

As long as the above three conditions are met, the cholera epidemic can be judged to be over. ”

After Gu Qingcen finished speaking, Gu Yanan, as the host of the meeting, began to make a concluding speech, "The desktop deduction of this cholera epidemic has designed a total of 5 scenarios and 11 questions, and all relevant departments participated in the deduction and explanation.

I would like to add here that in addition to the five scenarios involved in the deduction, there is another scenario that accompanies the entire epidemic at the same time, that is, risk assessment and epidemic research and judgment.

According to the relevant national regulations, after the occurrence of a public health emergency, professionals should be organized to carry out risk assessment, and put forward risk management suggestions to the government and health authorities, which will continue to be carried out according to the development of the epidemic, and the form of assessment is not limited to meetings, but can be discussed by telephone, video conferencing and other means.

If there is a sustained increase in the number of cases, a process risk assessment can be conducted.

The following is the discussion session. ”

As soon as Gu Yanan finished speaking and entered the discussion session, there was a sound of flipping books in the conference room, and some of the interns sitting in the last row began to look through the textbooks, and some began to discuss in a whisper.

An intern stood up and asked, "Director Gu, a few days ago, there was an intestinal infectious disease in our city, the causative bacteria is enterohemorrhagic Escherichia coli, is this outbreak the same as the cholera epidemic deduced on the table today?" ”

Gu Yanan: "Both are intestinal infectious diseases, and the emergency treatment methods are basically the same, except that cholera is a class A infectious disease, and enterohemorrhagic E. coli is a class C infectious disease, and the emergency response level is different." ”

Director Yang of the center added at this time, "The last enterohagic E. coli outbreak, the emergency response office handled it very well, and found the source of infection and controlled the spread of the epidemic before the laboratory determined the type of pathogen, which is the role that on-site investigation should play in the prevention and control of infectious diseases." ”

Someone raised his hand and asked, "Director Gu, if such a cholera epidemic really occurs, the public should have the right to know, how can we CDC announce the epidemic to the public?" Is it an epidemic notice? ”

Gu Yanan: "Every time there is an epidemic situation, there will be a summary report, the epidemic notice is issued by the health department, and our CDC also has its own spokesperson, and Director Yang is currently the spokesperson of our unit. ”

Director Yang of the center spoke, "Speaking of this press spokesman, I have a suggestion, Director Gu used to be the spokesperson of our disease control and control, and then for some reason, the spokesperson task fell to me as an old man, and now the emergency response office has a new member, I think the task of press spokesperson will be handed over to Gu Qingcen, after all, Xiao Gu's image is still very good." ”

Gu Qingcen has an outstanding image and a gentle temperament, and when he first came to the CDC, he caused a lot of sensation, but soon the gossip news spread that he came to CDC for Gu Yanan, so many people suppressed their careful thoughts about him.

As soon as Director Yang's proposal came out, Gu Qingcen immediately looked at Gu Yanan beside him.

Looking at each other, Gu Yanan understood what Gu Qingcen meant.

Gu Yanan rejected Director Yang's proposal, "Director Yang, Gu Qingcen is now a member of my emergency office, and our emergency team often has unannounced missions, and often exposing photos on TV is not conducive to work. ”

Gu Yanan's reason for refusing is impossible to refuse.

Director Yang coughed embarrassedly, "Well, this reason does have to be considered, I will retire from the second line in two years, and the task of the spokesperson will be handed over to Section Chief Zhang of the Health Education Section......"

Before Director Yang finished speaking, Gu Yanan's mobile phone rang.

The caller ID is a familiar number, which is the office number of the Boshan County Center for Disease Control and Prevention.

Picking up the phone and listening to what the other party said, Gu Yanan replied in a low voice, "Okay, I'll bring someone over immediately." ”

Hanging up the phone, Gu Yanan reported to Director Yang opposite, "Just now, the Boshan County Disease Control said that there was a suspected occupational poisoning incident in the local area, and I asked our city CDC to help investigate. ”

"Okay, your emergency team goes, today's desktop deduction is almost over, and I'll preside over the rest."

——

160 kilometers west of Lianhai City, Boshan County People's Hospital.

Gu Yanan and Gu Qingcen went to the hospital to learn about the patient's condition, and Lu Li, Wang Xiaoxiao, Zhou Lao and Gao Fei were sent to the paper mill to investigate the situation at the scene with local county disease control personnel.

Inside the hospital, a firefighter and Xiao Liu, a paper mill worker at the scene, are being treated.

Gu Yanan first found the attending doctor.

The attending doctor introduced the condition, "When the worker Xiao Liu was sent in, he had slight eye pain, dizziness and nausea; The symptoms of the firefighters are relatively severe, with general spasms, cyanosis of the skin and mucous membranes, miosis, weak heart sounds, rapid pulse, and shallow and rapid breathing.

When Xiao Liu, a worker, was admitted to the hospital, he reported that he smelled a strong smell of rotten eggs in the paper mill, and that the person who entered the pulping pool had electric convulsions and soon fell into a coma.

Based on the clinical symptoms and the situation at the scene, the preliminary diagnosis was occupational hydrogen sulfide poisoning.

At present, symptomatic treatment of hydrogen sulfide poisoning has been carried out. ”

After listening to the description of the attending doctor, Gu Yanan found the hospital bed and questioned the patient personally.

Worker Xiao Liu, with mild symptoms, after treatment, his mental state at this time has improved, and described the situation to Gu Yanan, "Lao Wang, the maintenance worker of our paper mill, went to the workshop to inspect and did not come back in the afternoon. Director Zhou went down to save people, and halfway down, he suddenly had convulsions and fell, and my two colleagues saw the situation at that time, and went down to save people, and they also fell.

I felt that something was wrong, thinking that there was a leak inside, so I called 119, and the firefighters rushed over to save people, but they also fainted inside, but fortunately they were pulled out by their companions.

There was a smell everywhere in that workshop, and I felt dizzy, so I called 120 and 110, and I was taken to the hospital, how happened to my colleagues? ”

Gu Yanan had already contacted the county disease control staff who were investigating at the paper mill and learned that they were wearing gas masks to salvage the four people who fell into the pulping pool.

Gu Yanan didn't want to hit the patient, so he said comfortingly: "At present, the rescue is still ongoing, you first cooperate with the doctor in the hospital for treatment." ”

As soon as the firefighters who were sent to the hospital woke up, Gu Yanan asked as usual.

The firefighter's voice was a little hoarse, "I felt dizzy and nauseous as soon as I got out of the pool, and soon I lost consciousness, I don't know how I got out or how I got to the hospital." ”

After listening to the descriptions of the two patients, Gu Yanan already had a general judgment, and now there is a need to have the results of the investigation on the site of the paper mill to characterize this incident.
