Immediately afterwards, I heard Director Zhu take Nan Zhiqiao's hand and say, "The last time we met was when we held a meeting at the CDC in China two years ago, at that time, it was Director Nan who gave us a report......

Ye Zhenzhen looked at the chubby director of disease control in Province G in front of her, who was also in her forties, but she didn't expect that she admired Nan Zhiqiao in her eyes, looking at his posture just now, this is to reminisce about the past. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Nan Zhiqiao withdrew his hand, glanced at the words on the big screen in the conference room, and said with a smile: "Director Zhu, let's start the epidemic report meeting first." ”

Director Zhu also took the opportunity to get to the point, leading Nan Zhiqiao and Ye Zhenzhen to sit down.

At the conference table in front of the big screen in the conference room, the two seats in the middle were vacated, and Director Zhu introduced the two of them into their seats and began to introduce at the same time, "This is the expert sent by the Chinese CDC to guide the handling of this outbreak, Director Nanzhi Qiao Nan. Then he looked at Ye Zhenzhen again.

Nan Zhiqiao said: "Ye Zhenzhen is a teacher in the same experimental group as me, and she is familiar with laboratory testing. ”

"Oh, this lady is an expert from China's CDC, Ms. Zhenzhen Ye. ”

Ye Zhenzhen was called an expert by someone in the system for the first time, and she couldn't help but feel uncomfortable for a while.

After the introduction, Nan Zhiqiao gave Director Zhu a look, and Director Zhu understood and immediately started the report meeting.

The report was made by another young man, who introduced himself as the person in charge of the on-site department, and the materials prepared in advance were projected on the big screen in the conference room in the form of PPT.

The person in charge began to introduce the process of the epidemic: " Three days ago, the CDC of Baishun County, B City, Province G, received a call from the masses that a suspected epidemic outbreak was found in Baizi Village, a family of four died, a 61-year-old man, a 59-year-old woman, and a 10-year-old and six-year-old girl. ”

A photo flashed on the big screen, in a simple rural brick house, there were two small corpses lying on the wooden bed by the window, both with two pigtails, two little girls, the girls' faces were covered with blood, and there was a large dark red blood stain at the head of the bed, and the blood stains were mixed with undigested food, which was bloody vomit.

In the next photo, in the muddy courtyard, two old men are lying on the ground, the old man is below, and the old woman is lying on the side, as if she wants to help the old man up.

Another photo, and the details of the corpses, the two old people's bodies had high bulging abdomen, obvious flatulence, and some scattered bloody vomit around the corpses.

The photographs are shown one by one, and the photos are clear, from the general location of the corpse, to the local details of the corpse, and the environment around the farmhouse.

Ye Zhenzhen looked at the photo and muttered in her heart: "Province G is also one of the top economic provinces in the country, but you can see the farmhouse in the picture, it is very simple, and the economic conditions of the villages where the epidemic occurred do not look good." ”

Looking at the appearance of the four corpses in the farmhouse, it was obvious that they had not been treated before their deaths, the onset was sudden, and the symptoms were very serious, Ye Zhenzhen couldn't help but ask: "The epidemic is so acute this time, didn't the neighbors of the deceased find any signs before they died?"

Ye Zhenzhen's question was sudden, which was very obvious in the originally silent conference room, and everyone's eyes looked over.

At this time, Ye Zhenzhen realized that she had asked suddenly, slightly embarrassed, Nan Zhiqiao seemed to sense Zhenzhen's embarrassment, and naturally added another question, "Can the time from the onset of the deceased to death be determined?"

The speaker cleared his throat and replied together: "The neighbors of the deceased went to the deceased's house two days before they found the deceased, that is, when they went to the deceased's house on November 1, they did not find anything unusual about the four grandchildren, and then found that the door of the deceased had not been opened, and they went to knock on the door at noon on November 3, but no one answered, and they felt that something was wrong, so they broke into the door and found that the four grandchildren were dead at home, and then called the police, and after the police checked it, they felt that it was an infectious disease, so they reported it to the county CDC." ”

Ye Zhenzhen wondered in her heart, what kind of disease can make people die quickly in just two days, and they didn't even have time to go to the city for medical treatment......

Nan Zhiqiao suddenly pointed to the big screen in the conference room, "Wait a minute, change to the photo just now." ”

The presenter slid the mouse in his hand, and the photo on the big screen was restored to the one just now, which was a close-up photo of the hand of a man in his sixties.

The man in the photo is lying face down on the ground, with his hands stretched forward above his head, and in the zoomed photo, his hands are swollen, and there is a visible black crust necrotic area on the second knuckle of his middle finger.

"Skin anthrax!" Seeing the black scab necrotic area on the old man's finger, Ye Zhenzhen couldn't help but muttered quietly beside Nan Zhiqiao.

The black scab formed by the ulceration on the old man's finger is very similar to the "anthrax carbuncle" in the anthrax of the skin, which Nan Zhiqiao must also be able to see.

Nan Zhiqiao did not respond to Ye Zhenzhen, but asked the speaker, "What are the test results of the specimens collected from the deceased?"

The screen was changed to a picture of laboratory testing, a microscope photo, the purple streptobacterium is obvious, "The local municipal CDC isolated the Gram stain-positive bacilli from the specimens of the deceased, and at the same time, the specimens sent to the laboratory of the Provincial CDC were detected by PCR to detect the specific nucleic acid fragments of Bacillus anthracis, and today, the laboratory staff are using plasmid electrophoresis and other strain typing methods to determine the source of infection and transmission route." ”

Ye Zhenzhen began to muttered in her heart again, since it has been determined that the pathogen is Bacillus anthracis, this epidemic is an anthrax epidemic, and it is not enough to deal with it according to the treatment method of the anthrax epidemic? Why do you still need to ask experts from the Chinese CDC to assist in dealing with it? The handling of the anthrax epidemic has a guidance manual with almost standardized operating procedures, controlling the source of infection, treating the wounded and sick, disposing of the crowd, and eliminating pollution.

Ye Zhenzhen was wondering in her heart, and Nan Zhiqiao asked very experiencedly: "What is the problem of this anthrax epidemic that is not easy to solve?"

The keynote speaker didn't expect Nan Zhiqiao to ask the key question directly, and his eyes couldn't help but look at the location of the big leader, Director Zhu.

Director Zhu then explained: "The handling of this anthrax epidemic is proceeding in an orderly manner, but today, through strain typing, our provincial CDC laboratory personnel found that the Bacillus anthracis isolated from the deceased in Baizi Village has very low homology with the anthrax strain that was previously circulating in City B of Province G, and we highly suspect that this anthrax epidemic is not caused by a strain from the natural foci of City B." ”

Ye Zhenzhen was a little confused, it was not caused by the local epidemic strain? That is, it was foreign, was it introduced by animals? Or was it brought in by outsiders? No matter what the source of infection and the transmission route were, these are all things to be solved in the on-site epidemiological investigation.
