"What's the matter?" asked Ye Zhenzhen nervously. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"Several more children in the centre have fever and bleeding. Sister Jiang paused slightly, "They can't be infected by An An, right?"

"Then who was An An infected by?" Ye Zhenzhen said the crux of the problem.

Sister Jiang was speechless for a while, where is the source of this infection?

Ye Zhenzhen keenly felt that this incident in the child welfare center must be an infectious disease, and it is related to the illness of Grandpa Sun in the nursing home next to it, and the source of infection must be near the child welfare center and the nursing home, and the source of infection must be found as soon as possible to prevent the further spread of the epidemic, but before finding the source of infection, we must first look at the situation of other sick children in the child welfare center.

Since she can't help in the hospital, let's investigate the matter clearly and make up her mind, Ye Zhenzhen immediately asked Sister Jiang, "Where are the other children who are sick?"

"A few people with severe symptoms have been sent to the district hospital, and a few with mild symptoms are still in the center. ”

Ye Zhenzhen said her plan, "I will first go to the district hospital to see the children who have just been admitted to the hospital, and then go to the child welfare center to see if I can find clues to the source of infection." ”

Sister Jiang nodded and agreed: "Okay, you go, I'm here to guard An An." ”

Seeing that Zhen Zhen was about to leave, You Kexin chased after him and said, "Zhen Zhen, I'll go with you." ”

Liang Chen also came up, "Count me in, I'll send you over." ”

Ye Zhenzhen considered that this time it was likely to be a virulent infectious disease, and that You Kexin was still in the recovery period of radiation sickness, let alone contact with these dangerous infectious diseases, Ye Zhenzhen refused and said: "No need, I can do it alone, let Liang Chen send you back first, and I will inform you when there is a result." ”

You Kexin still wanted to fight, but Liang Chen grabbed Kexin and said: "Just listen to Zhen Zhen, she is a professional in China's CDC, she knows how to investigate, how to protect herself, we can only make trouble with the past, go home and wait for news." ”

You Ke thought about it, too, so he retreated to Liang Chen's side.

Ye Zhenzhen ran out of the hospital alone, planning the nearest transportation from JS Hospital to the district hospital, and just while waiting for the bus, she received a call from Nan Zhiqiao.

Nan Zhiqiao had just finished dealing with things from the Health and Family Planning Commission, and originally wanted to call Zhen Zhen to have dinner together, but he didn't expect to hear the news that An An was seriously ill and hospitalized, as well as the situation in the child welfare center, and an intuition told Nan Zhiqiao that a virulent infectious disease was about to break out.

After asking Ye Zhenzhen's plans, Nan Zhiqiao ordered Zhen Zhen to wait in place, and more than ten minutes later, Nan Zhiqiao appeared at the bus stop in a car.

Ye Zhenzhen sat in the co-pilot's seat, and Nan Zhiqiao drove towards the district hospital.

On the way, Nan Zhiqiao listened to Ye Zhenzhen's analysis of the whole thing, as well as the connection between Grandpa Sun's illness in the nursing home and the emergency incident in the child welfare center.

In the district hospital, the children who had just been sent by the child welfare center were arranged in a unified ward, Nan Zhiqiao showed his work card, and with the consent of the district hospital, the two entered the ward and checked the medical information of several children.

Looking at the physical signs of several children, they were all red, and their chests and backs were covered with bleeding spots, and they asked several older children who were conscious, and they all complained of headaches, orbital pain, and low back pain.

Ye Zhenzhen and Nan Zhiqiao glanced at each other, and Nan Zhiqiao instructed: "Contact the infectious disease department of the district hospital, ask them to send the blood samples of these children directly to our laboratory at the CDC in China, and then inform Zhang Xiaolong to use PCR to amplify the three fragments of hantavirus L, M, and S from the blood, and after the amplification, sequencing will be carried out immediately." ”

"Okay. Ye Zhenzhen agreed, and began to contact the infection department, and then contacted Zhang Xiaolong of the experimental group.

After Ye Zhenzhen finished the call, she saw that Nan Zhiqiao also happened to hang up the phone, Ye Zhenzhen asked, "Senior Nan, where will you go next?"

Nan Zhiqiao asked rhetorically, "What do you think we should do next?"

After receiving the epidemic report from the hospital, the district CDC should immediately rush to the hospital to verify the diagnosis of the case and conduct on-site epidemiological investigation.

"We should now conduct a field epidemiological investigation. ”

Nan Zhiqiao nodded, "Very good, then according to your idea, how do you start the on-site epidemiological investigation?"

"Understand the environment that the patient was exposed to before the onset of the disease, whether he came into contact with a fever patient or the host animal that transmitted hemorrhagic fever, and register and observe the patients, relatives and friends that the patient came into contact with. All we have to do now is go to child welfare centers and nursing homes and investigate and inquire. ”

Nan Zhiqiao: "Okay, the theoretical knowledge is used well, next, we are divided into two ways, you have already done an investigation of the nursing home, this time again, the focus should be on the connection between the nursing home and the child welfare center, I will go to the child welfare center to see other children who are not hospitalized, if necessary, may also be isolated and treated." ”

According to Nan Zhiqiao's arrangement, the two went to a nursing home and a child welfare center respectively.

――

In the nursing home, Ye Zhenzhen found the fat old man Grandpa Sun again, bypassed the topic he had asked before, and directly asked the fat old man if he had been to the child welfare center next door, the fat old man denied it, and asked if there were any children from the child welfare center who had come, but the fat old man still denied it.

Ye Zhenzhen thought to herself, since there was no direct contact between the two parties, maybe it was through other media, could it be the volunteers of both sides, or the animals that both sides could reach?

Ye Zhenzhen asked the fat old man if there were any volunteers from the child welfare center who came to work in the nursing home recently, and the fat old man glanced at Ye Zhenzhen and said, "I only know you." ”

Ye Zhenzhen was stunned, although she ran on both sides of the child welfare center and the nursing home, but two weeks before An An became ill, she had not visited him, and the chance of infection was not great, so she had to change her clues.

"Grandpa Sun, what animals have you been in contact with recently, such as dogs, cats, birds, mice, fish......

Ye Zhenzhen listed the names of various animals one by one, and the fat old man was a little impatient, "Zhenzhen little girl, you have asked me three times, and I have answered the same every time, except for the local dog at the gate of the nursing home, I have never touched other animals." ”

Is there any other way of transmission besides humans and animals? Ye Zhenzhen thought in her heart, muttering at the same time: "Since there is no direct and indirect contact, why do children in the child welfare center get sick?"

"Child welfare center?" the fat old man asked, "are the little children in there sick too?"

Ye Zhenzhen nodded, "Well, many children have been hospitalized, their symptoms are the same as your previous ones, and one child has been notified of critical illness by the hospital. ”

Guilt flashed in the fat old man's eyes, and there was a sudden change in this point, and Ye Zhenzhen looked at it in her eyes, Ye Zhenzhen asked euphemistically: "Grandpa Sun, is there anything else you haven't told me, you recall it carefully, the clues you provide are very important, based on your contact experience, we may find the source of infection, so that more people can be prevented from being infected." ”

The fat old man thought for a moment, and finally as if he had made up his mind, he said, "I bought a squirrel as a pet." ”
