Several people went to the West Wing and found Xiao Chu standing next to a white fur, which was propped up in the air with several wooden sticks.

The fur is shaped like a dog's skin with its limbs forcibly propped open.

The fur on the head is still intact and can be contoured, with a pointed nose and short, slightly pointed ears.

"It's a fox skin, put it in a sampling bag, and take it back."

Xiao Chu carefully removed the fox fur from the wooden stick, folded it slightly, and put it into the sampling bag.

Seeing this, Xiao Zhang, a young staff member of the county disease control who didn't know when he followed up, asked in a low voice: "There won't be fleas on the fox's skin, right?" ”

Lu Li: "Fleas like to stay on living creatures, this fox skin has been dried for many days at a glance, and the fleas have long left." ”

"Oh, I've got a preliminary flow report here." Xiao Zhang took out a few questionnaires and handed them to Section Chief Li.

Section Chief Li glanced at it and handed it to Gu Yanan.

The questionnaire provides a detailed record of the health of the villagers in Lijia Village and four nearby villages, as well as their experiences in the last few days.

At present, 12 villagers have developed fever, cough and other initial symptoms of pneumonic plague.

What worries Gu Yanan is that 10 of the 12 people have attended Li Erzhu's funeral, of which 6 are in Lijia Village, and the remaining 4 are distributed in the surrounding four villages, all of whom are relatives of Li Erzhu, and the other two have not attended the funeral, but have been in contact with the people who attended the funeral.

In other words, in just 3 days, there have been second-generation cases.

This is a sign of the further spread of the epidemic.

At this time, Gu Yanan's mobile phone rang.

The CDC called, "Just now I tested the patient specimens sent by the Qingcheng County People's Hospital, and found a large number of gram-negative short bacilli in the sputum specimens under the microscope, and the PCR tests for FRA, PLA, INV and HMS-specific genes were all positive. ”

Sure enough, it's the plague!

"Lu Li, electronic map."

Lu Li immediately took out the tablet he was carrying, opened the electronic map, and put it in front of Gu Yanan.

Gu Yanan drew a circle on the electronic map with Lijia Village as the center, "Suggest to the people's government of the municipality directly under the central government to initiate a second-level response to major public health emergencies and implement first-level control over the areas within the circle." ”

Lu Li: "Okay, I'll write a description of the situation here, and send it directly to Director Yang of the center after I write it?" ”

"Well, I will call and communicate with Director Yang first, and you can send me the materials first."

"Okay."

Section Chief Li of the county CDC has experience in dealing with this situation and discussed the next countermeasures with Gu Yanan.

"Director Gu, the handling measures this time are the same as the plague epidemic in Wangjia Village and the thousand-year-old tomb next door?"

"Well, it's the same as last time. I would suggest that the city send a team of medical experts, and the county health department should also send an emergency team.

First of all, according to the identification on the electronic map, the warning area and the size of the isolation ring are determined, and the isolation circle is subject to first-level control.

The neighboring villages of Lijia Village and the four surrounding affected villages were classified as warning areas, the five affected villages were classified as large isolation circles, and the affected households were classified as small isolation circles.

In the warning area, the transportation of materials and the entry and exit of personnel are restricted, and disinfection stations are set up on traffic arteries to disinfect personnel or vehicles that must enter and exit the epidemic area.

In the large isolation circle, sentry posts are set up at the entrance of the village to prohibit people from entering and leaving, and villagers are prohibited from visiting each other; Carry out poisonous bait to kill rodents and fleas; Disinfect corpses and cemeteries.

In the small isolation circle, the house, livestock pen and toilet are repeatedly disinfected to eliminate rodents and fleas in time.

Second, isolate and treat existing patients and control the source of infection.

Isolate patients in situ.

Except for disease control and medical personnel, who can enter and exit under strict protective conditions, other personnel are strictly prohibited from entering and leaving.

The isolation of patients and close contacts should not be lifted until two weeks after all signs and symptoms have disappeared.

Urgently allocated treatment drugs from the city, mainly streptomycin and sulfonamides.

The third step is to urgently vaccinate against plague to strengthen the immunity of the villagers.

The scope of vaccination is for residents of villages within 5 kilometers along the Lijiacun Highway.

The city has a stockpile of plague vaccines, and the application is for immediate allocation.

The fourth step is to follow up and observe the health contacts.

All those who have been in close contact with the patient in the two villages will be followed up and examined, and if suspected symptoms are found, they will be given medical treatment in a timely manner, and the isolation time will also be two weeks.

The fifth step is to publicize and educate and arrange the production and life of villagers in the epidemic area.

Door-to-door dissemination of plague symptoms and prevention and control knowledge, and temporary shutdown of work and production in first-level control areas. ”

Section Chief Li nodded again and again, "Okay, the prevention and control measures are basically the same as last time, I now organize personnel to set up sentinels on the main roads first, and then set up medical tents in the compound of the village committee to serve as a temporary headquarters." ”

Gu Yanan was about to ask Section Chief Li to take someone to get busy, when he suddenly found that there was a problem in the flow meter.

"Section Chief Li, there are a total of 57 people who have participated in Li Erzhu's funeral, and this is the case flow information of 53 people, what about the information of the other 4 people?"

Section Chief Li has been investigating with Gu Yanan at the home of Li Erzhu, the first case, just now, and the investigation of close contacts of the funeral has always been followed up by Xiao Zhang of the county disease control.

Xiao Zhang replied to Gu Yanan, "The remaining 4 people are Li Erzhu's daughter's family, who live in the next province H, and after the funeral, the family went back on the same day, because it is more troublesome to transfer in other provinces, so there is no information about that family at present." ”

"Send a letter of investigation to the H Provincial Disease Control and Development Association, as soon as possible!"

Xiao Zhang hurriedly agreed, "Okay, I'll go to the association to check the letter now." ”

Xiao Zhang trotted away, and immediately began to contact his colleagues who were still in the office, preparing to send a letter to the H Provincial Disease Control and Prevention Association.

Gu Yanan looked at the information and asked Section Chief Li, "How did the body of Li Erzhu, the first case, be handled?" ”

Section Chief Li was stunned for a moment, but then replied: "According to the customs here, I went to the county crematorium to be cremated the day after my death, and then put the ashes in the coffin and buried them in the cemetery of Lijia Village at the foot of Qingcheng Mountain, and finally the funeral farewell banquet flowing water banquet, and the people who participated in the funeral all ate the flowing water banquet, that is, 57 close contacts." ”

"Who picked up the body to the crematorium?" Gu Yanan grasped the key point of the problem.

"It seems to be a hearse sent by the crematorium to pull over the body, and then to deliver the coffin and ashes."

"How many people are there?"

Section Chief Li was sweating on his forehead, and he was in a hurry, and he actually missed such an important close contact!

"I haven't checked it yet." Section Chief Li felt that his voice was already a little trembling, if the entourage on the hearse was infected, then this person was like a mobile source of infection, and wherever he went, he would cause an outbreak of the epidemic.

Gu Yanan was anxious, but his voice was still quiet, "Go and check, you can't miss any close contacts." ”

There was already a serious shortage of manpower, and Gu Yanan was about to call Zhou Lao, who was being transferred to an inpatient in Qingcheng County Hospital, but Zhou Lao's phone came first.

Zhou Lao's voice on the phone was a little hurried, "Director Gu, the situation in the county hospital is not good, two more patients have died, including Li Erzhu's son, and after investigation, the two deceased patients were the attendants who transported Li Erzhu's body to the crematorium, and the one who died today was the driver of the hearse, and so far, all the hearse personnel who transported Li Erzhu's body have died." ”
