The symptoms described by Wang Gangqiang are consistent with the clinical symptoms of the acute phase of brucellosis.

Gu Yanan then deduced from the body appearance characteristics of the deceased Wu Dali at this time that he was very likely to die of cloth disease.

Gu Yanan asked Wang Gangqiang, who was standing at the door of the dormitory, "What kind of work does your roommate Wu Dali usually do in the ranch?" ”

"I'm in charge of adding feed to the cattle and sheep, cleaning the pens and so on, I usually do similar work to him, he is in charge of the east area, and I am in charge of the west area...... Doctor, Wu Dali, does he have an infectious disease? Am I going to have the same disease as him? ”

Gu Yanan didn't answer, but continued to ask: "I'll take a blood sample for you later, where is the enclosure that Wu Dali usually cleans?" ”

"East Hillside."

Wang Gangqiang pointed to the eastern hillside, where flocks of sheep were grazing on the dead grass on the hillside, and several white-roofed enclosures were scattered along the hillside.

Wang Gangqiang said: "The east slope is a sheepfold, which has recently introduced new breeds of goats from other provinces, the boss is very good for these sheep treasures, and specially instructed Wu Dali to take good care of them, and often go to feed them in the middle of the night before Dali is sick." ”

"Take us to see it."

"Oh."

Wang Gangqiang and Manager Zhang took the people from disease control to the east slope.

Before leaving Wu Dali's dormitory, Gu Yanan looked at Nan Hanfei, and stopped talking, but Nan Hanfei also had the same expression.

When the policeman Xiao Li saw it on the side, he muttered in his heart: Is the legend true? Team South and Director Gu are really not boyfriend and girlfriend? The two were acting before?

In the end, the two still didn't speak, and Gu Yanan turned his head and left.

Nan Hanfei looked at Gu Yanan's back and gradually walked away, a trace of sadness flashed in his eyes, and he suddenly stood a little unsteadily.

The policeman Xiao Li found out that Nan Hanfei was abnormal, and hurriedly stepped forward to help, and asked worriedly: "Boss, are you not feeling well?" Is the headache again? ”

Nan Hanfei stabilized his mind and stood firm again, "It's okay." ”

Policeman Xiao Li saw Nan Hanfei's somewhat pale face, and knew that he was holding on, "Team Nan, the matter here is almost the same, leave the rest to them to deal with, I'll send you back first." ”

Nan Hanfei had a terrible headache, worried that if he fainted before, it would be bad if he was found by Gu Yanan, so he followed the advice of the policeman Xiao Li, "Okay, let's go back first." ”

——

Green Valley Ranch, East Hillside, Sheepfold.

A few white lambs were curled up in one corner of the fold to rest.

Standing next to the sheepfold, Manager Zhang introduced Gu Yanan: "These are the new goats introduced by our ranch a month ago, this kind of goat meat is tender and very popular with customers. ”

The lamb huddled in the sheepfold was listless, as if he was sick.

"Are these sheep sick?" Gu Yanan asked.

Manager Zhang's face was embarrassed, "In winter, animals are more likely to get sick, it may be that the temperature difference between day and night is large in the past two days, and our workers have not done a good job of keeping the sheepfold warm, it's okay, give them some medicine and it will be fine." ”

"Do you know the owner of the barbecue stall at the East Lane Exit of the East Lane Food Street in the University Town of the Eastern District? He bought sheep from you. ”

"There are so many customers who come to our ranch to buy sheep, how can I remember everyone?"

Gu Yanan flipped out a photo on his mobile phone, which was taken at the entrance of Dongxiangkou at that time, and there was a frontal photo of the barbecue stall owner.

"Have you seen this person?"

Manager Zhang glanced at the photo on the mobile phone screen and nodded, "I think about it when I look at it, there is such a person, who came to the ranch to select sheep a few days ago, and was very picky and picky, and finally picked two from our new batch of goats." ”

"How many of these new sheep have been sold?"

"Just sell those two, our ranch owner wants to keep these sheep to breed by himself, because I sold those two, and I said that I would be killed."

Manager Zhang remembered that the purpose of the CDC's investigation was cloth disease, and suddenly reacted, "You don't suspect that this batch of sheep has cloth disease, right?" How can it be? This batch of sheep was personally introduced by our boss from a ranch in another province, and the owner of that ranch is friends with our boss, how can he sell us a batch of sick sheep? ”

Gu Yanan ignored Manager Zhang's questions and began to sample the surroundings of the sheepfold and the goats inside with Lu Li.

After collecting the samples, Gu Yanan collected blood samples from all the staff of the ranch, and before leaving, he instructed them to go to the First People's Hospital for further examination.

Because a worker had just died, and the disease control personnel were wearing bioprotective clothing, the other staff of the ranch were very cooperative, and before the disease control flow left, some workers had already taken the car to the hospital by themselves.

Lianhai Center for Disease Control and Prevention, Emergency Office.

The results of the experiment on specimens collected from the Green Valley Ranch are in.

Brucella was found in the bodies of twelve sheep, in the goat's milk in the barbecue stall at the mouth of the East Lane, and in the bodies of three ranch workers who were responsible for cleaning the sheepfold on the slope of Dongshanpo, including the deceased Wu Dali.

Gu Yanan issued a timely epidemic notification in the name of the CDC.

With the cooperation of relevant departments, the Green Valley Ranch was temporarily closed, the infected workers were hospitalized for treatment, and the sick sheep were culled and treated harmlessly.

Gu Yanan continued to trace the source of the sick sheep.

The sick sheep in Lianhai Green Valley Ranch come from a ranch in neighboring provinces and cities - Qingling Ranch.

With the assistance of the CDC of neighboring provinces and cities, the final source of the sick sheep infected with the disease was found - Qingling Ranch.

It turned out that the sheep in Qingling Ranch broke out of the disease a month ago, and the rancher did not report the epidemic, but simply buried the dead sheep, and continued to sell the live sheep in the early stage of infection, resulting in the spread of the disease epidemic in neighboring provinces and cities.

One of the sick sheep in Qingling Ranch was purchased by Green Valley Ranch in Lianhai City, resulting in the infection of three workers in Green Valley Ranch, one of whom died in the acute stage of the disease.

Green Valley Ranch sold two of the sick sheep to the owner of a barbecue stall at the entrance of Dongxiangkou Food Street in University Town, East District, causing the freshmen of the School of Economics and Business who went to eat barbecue to be infected.

The source of infection and the route of transmission have been investigated.

Soon, the outbreak was brought under control, the epidemiological investigation was concluded, and Gu Yanan wrote a summary report after the end of each outbreak as usual.

After the report was written, it was already dark, but Gu Yanan's mobile phone suddenly received a message.

It was Nan Hanfei who sent the message.

Since Gu Yanan told Nan Hanfei that he didn't need to pretend to be a boyfriend anymore, Nan Hanfei hadn't taken the initiative to contact him for a while.

Gu Yanan felt that Lanan Hanfei was a little unkind when he was a shield in front of his parents before, and he was embarrassed to take the initiative to contact him.

Today, Nan Hanfei suddenly sent a message, and Gu Yanan was a little surprised.

The content of the message is very short, "sincerity, gold and stone for the open".

Gu Yanan didn't understand what it meant, and replied with a question mark.

Nan Hanfei sent another heart-shaped pattern.

No matter how dull Gu Yanan is, this time he understands that Nan Hanfei has not given up his plan to chase her.

Gu Yanan hesitated for a moment, feeling that it was best not to drag his feet on emotional matters, and replied directly, "I'm sorry, you're very good, but I don't want to have a boyfriend at the moment." ”

"It's okay, I can wait, wait until I make a place in my heart for me."

Gu Yanan felt that Nan Hanfei was using a stalking trick, but she didn't understand, she had known him for a short time, how much could a person like another person in such a short time?

If a person who has been with him for more than 20 years can just leave, then what can a person who has only known each other for half a year?

"Why do you like me?"

"There's no reason, just like."

"I don't believe in love at first sight."

"We didn't fall in love at first sight, we were meant to be."
