Wang Xiaoxiao: "Not necessarily, it may be because of raw goat's milk, or it may be because of eating undercooked meat skewers, or it may be that it has been in contact with infected cattle, sheep, pigs and deer, or maybe it has been in contact with their feces, or it may even be that you have breathed the air around the infected animals......"

The barbecue stall owner's face turned pale with fright, "You can be infected when you take a breath?" Really? ”

Wang Xiaoxiao nodded seriously: "Really, if you have come into contact with animals infected with the disease, even if you have been to the enclosure of infected animals, it is entirely possible to be infected." ”

Looking at the pale face of the barbecue stall owner, Wang Xiaoxiao felt a little pleasure in his heart that the conspiracy had succeeded, and thought: Let you hinder our inspection just now, scare and scare you first.

Gu Yanan glanced at Wang Xiaoxiao, Wang Xiaoxiao stopped in time, turned away and continued sampling.

The barbecue stall owner stared at Wang Xiaoxiao's back and asked, "You won't be scaring me, are you?" Can you be infected if you have been to a sheepfold? ”

Gu Yanan: "It's not to scare you, but the disease is inherently scary, and the sheepfold of the infected sheep will be filled with aerosols containing Brucella, and if you breathe it into the lungs, you will be infected." ”

"I've been to Green Valley Ranch, and every time I buy sheep, I personally go to the sheepfold to pick them, and the sheep there look alive and not sick."

"Whether you are infected with brucellosis or not, the specific route of infection will have to wait for our test results, so we also need a blood sample from you."

The owner of the barbecue stall was very cooperative, rolled up his sleeves, and asked Wang Xiaoxiao to collect blood.

Lianhai Center for Disease Control and Prevention, Laboratory.

Samples taken from the barbecue stand quickly came back with results.

Brucella nucleic acid was detected in the blood of finished lamb skewers, half an unprocessed lamb, and the owner of the barbecue stall.

Gu Yanan notified the barbecue stall owner to go to the hospital for treatment, and at the same time arranged for Gao Fei and Wang Xiaoxiao to go to the barbecue restaurant for thorough disinfection, while Gu Yanan began to find the source of the epidemic.

The diseased lamb in the barbecue stall came from the Green Valley Ranch, and Gu Yanan went to the Green Valley Farm to find the initial source of infection.

——

The eastern suburbs of Lianhai City, Green Valley Ranch.

Green Valley Ranch is located in the eastern suburbs of Lianhai City in the hilly area, the whole ranch is a large hilly slope, surrounded by a wooden fence.

There are several simple cattle and sheep pens on the hillside, and there is a row of brick houses with white walls and gray tiles at the door, which is the residence of the ranch staff.

In winter, the pastures are gray and yellow, and the cattle and sheep need to be fed artificial feed.

Gu Yanan and Lu left the scene and stopped outside the wooden fence gate of Green Valley Ranch.

Also outside the fence gate were two police cars.

Lu Li parked the on-site flow shunting car not far from the police car, and after getting out of the car, he looked at the police car and asked: "Why is there a police car here?" It can't be a homicide, right? ”

Gu Yanan glanced at the license plate number of the police car, which was very familiar, it was the car of the Municipal Criminal Investigation Brigade.

Could it be that there is a murder in the ranch.

Gu Yanan carried the sampling box and stepped forward to knock on the door.

Behind the fence gate came a ranch worker, a lean old man in his sixties, who looked like a security guard who usually guards the ranch.

"Hello, I am a staff member of the Municipal Disease Control and Prevention, and I am here to investigate an epidemic of the disease." Gu Yanan showed his work card and explained his intentions at the same time.

The thin old man's face was suspicious, "Now the dead are also under your disease control?" ”

Lu Li followed Gu Yanan's side, stared at the old man of the security guard, and asked very gossipyly, "Is it really dead?" ”

"Didn't you come because you were dead?" The old security man asked rhetorically.

"We CDC came to investigate the outbreak of the disease, who died in the ranch? How did he die? Gu Yanan asked.

"Xiao Wu of our ranch, I have been uncomfortable for the past two days, but I was found dead in the dormitory this morning, we called the police, the police are investigating, I don't know how Xiao Wu died, wait, what are you doing with disease control? Investigating the outbreak? Cloth disease? Is there a disease on our ranch? The lean old man who was guarding the door seemed to be only now reacting.

"I found out after checking, but we are sure that some of the sheep you sell are infected with the disease, so to investigate, we need to collect cattle and sheep specimens from the pasture, as well as blood samples from the ranch staff."

The old security man called to report the ranch manager, and soon, a man in his thirties trotted out.

"Manager Zhang, the people from disease control are going to enter our ranch to investigate and sample." The old security guard made another verbal report to the manager.

Manager Zhang saw Gu Yanan, and tried to squeeze out a little smile on his ugly face, "I'm sorry, something happened to the ranch today, and the police are dealing with it inside, you want to sample cattle and sheep, right?" I'll take you there. ”

Under the guidance of Manager Zhang of the ranch, Gu Yanan and his party walked through the dormitory area on the inside of the ranch gate, and were about to walk to the cattle and sheep pen on the hillside.

After walking a few steps, Gu Yanan saw a cordon set up outside the dormitory.

There are busy police officers in the cordon.

Gu Yanan stopped and turned his head to walk in the direction of the cordon.

Manager Liu hurriedly followed behind Gu Yanan, "Director Gu, aren't we going to the cattle and sheep pen......

"Let's look at the deceased first, maybe his death is related to this epidemic."

Lu Li found Nan Hanfei and policeman Xiao Li in the cordon at a glance.

Nan Hanfei also saw Gu Yanan who came over.

Nan Hanfei: "Is there an epidemic here? ”

"Hmm." Gu Yanan stared at the deceased in the dormitory and asked Nan Hanfei, "Is it a criminal case?" ”

"A criminal case has been preliminarily ruled out, there are no traces of a fight at the scene, and the deceased should have died of illness."

"There may be an outbreak of brucellosis here at Green Valley Ranch, and the deaths may be related to this outbreak."

Nan Hanfei picked up the cordon and made a gesture to invite in, "Our on-site evidence collection work has been completed, you can come in and take samples." ”

Gu Yanan and Lu Li entered the scene.

The dormitory was a two-person room, one of which had a single bed in which the deceased lay down.

Gu Yanan began to check the deceased, Nan Hanfei introduced on the side: "The deceased Wu Dali, male, age 21, high Chinese, is a breeder employed by Green Valley Ranch, working in the ranch for one year and seven months, according to his roommate Wang Gangqiang, Wu Dali began to have a cold and fever a week ago, has been taking cold medicine, yesterday began to get sick, asked the manager for sick leave, this morning after the roommate got up, found Wu Dali dead in bed. ”

Wang Gangqiang, a roommate who had just finished taking notes with the police, stood at the door of the dormitory, watching the disease control personnel in white protective clothing inspect Wu Dali's body.

Wang Gangqiang thought to himself, it is said on TV that as long as there are disease control personnel, there are infectious diseases everywhere, could it be that his roommate Wu Dali died of infectious diseases? If I live with him all day, will I be infected?

In order to confirm his thoughts, Wang Gangqiang took the initiative to react to Gu Yanan, "Wu Dali began to feel uncomfortable a week ago, he said that he always sweated at night, and he was still in pain when he got up the next day, and he didn't want to work, at first I thought he was lazy, but after two days, he had a lot of blisters on his body, and he limped when he walked, and he coughed up blood before going to bed last night, yelling at him for a headache, I asked him to go to the hospital to see, he said to sleep one night, and come to the hospital again this morning." I went to the city with my friends last night and came back very late, and when I came back I found him lying quietly in bed, I thought he was okay, who would have thought to get up in the morning and call him, he ...... He was already cold, and he was stiff. ”
