Some bold villagers directly approached the disease control staff who were investigating on the spot in the village and asked, "How can swine fever infect people?" Last year, there was also a swine fever in our village, and everyone was fine. ”

Zhou Lao had an impression of the swine fever that the villagers said about last year, and it was he and people from the Animal Husbandry Bureau who came to the scene to supervise the handling of the epidemic.

"What happened last year was African swine fever, the pathogen is a virus, which only infects pigs and does not infect humans, but what is happening now is Streptococcus suis, which is a zoonotic disease that can infect people, and the fatality rate is still very high." Zhou Lao explained to the villagers.

"There are so many kinds of swine fever? How can this be distinguished? Who knows which time to infect people? Which time is not infectious? Pigs often get sick anyway. The villagers muttered quietly, their eyes couldn't hide their panic, now every household in the village has pigs, according to the current situation, this pig can't be raised in the future?

"No matter what kind of swine fever outbreak, as long as there is a dead pig, they can not be slaughtered, let alone eaten, nor can they buy pork from unknown sources.

The villagers around Zhou Lao seemed to suddenly think of something, and took the initiative to reflect the situation, "Comrade of disease control, I have a situation to reflect, Zhao Yongfa raised two big white pigs, and he said before that one of them would be killed and sold to a butcher, and the butcher often walked the streets and alleys to resell pork, and the meat he sold was cheaper than ordinary traders, and he often operated in Lijia Village next door. ”

This is an important clue.

Previously, the county disease control staff had been tracking down the butcher who bought Zhao Yongfa's sick pork, but there had been no clues, but I didn't expect to hear it from the villagers.

According to the clues provided by the villagers and the name provided by Zhao Yongfa, the CDC team successfully found the meat dealer.

According to the clues provided by the butchers, the disease control staff found all the sick pork sold, took all of them back, brought them back to the CDC laboratory, and conducted physical examinations and samples on those who bought and ate the pork.

When the villagers were sampled, it was found that some people had fever symptoms, and Zhou Lao arranged a car to send them to the hospital in time.

In the afternoon of the same day, Mr. Zhou and his entourage brought back the people, pigs and environmental specimens collected from Zhaojia Village, as well as the sick pork that was recovered.

That evening, the results of the experiment came out.

Streptococcus suis type 2 was detected in sick pigs, febrile villagers and environmental specimens in Zhaojia Village.

On the second day, Gu Yanan arranged for colleagues from the sanitizing department to assist the county disease control to go to Zhaojia Village to deal with sick and dead pigs and carry out on-site disinfection.

The hospital also gave antibiotics to the patient and his condition was brought under control.

A few days later, all the sick and dead pigs in Zhaojia Village were treated, and the site was disinfected, and no new patients and sick pigs appeared.

Gu Yanan is writing a summary report on the human outbreak of Streptococcus suis.

In Zhaojia Village, at the foot of Yuntai Mountain, two large white pigs of villager Zhao Yongfa's family were infected with Streptococcus suis.

Zhao Yongfa and his cousin Zhao Yongcai slaughtered two sick pigs and ate them.

When Zhao Yongfa's family was handling the pig's water, they were stabbed by the pig and infected with Streptococcus suis, and became ill within 4 hours.

Zhao Yongfa and his younger brother Zhao Yongcai ate undercooked sick pork and fell ill on the way to the hospital with their family.

Pork vendors sold pork from Zhao Yongfa's illness to Lijia Village, infecting two villagers.

The presence of type 2 Streptococcus suis in the environment outside Zhaojia Village is a high rate of germ carriage in the pig herd of Zhaojia Village.

Villager Xiao Song's pigs also carried type 2 Streptococcus suis, after slaughtering, the family became ill, and the nanny Xiao Song brought her sick pork to Uncle Ge's house, where she was infected while handling pork.

Streptococcus type 2 cannot be transmitted through the air, only through contact or fecal-oral transmission, through the treatment of sick and dead pigs and disinfection of the external environment, the source of infection is eliminated, the transmission route is cut off, and the epidemic of people infected with Streptococcus suis in Zhaojia Village is controlled.

Evening.

Lianhai City, Xinhua Apartment.

Gu Yanan bachelor apartment downstairs.

Nan Hanfei parked his car in the parking space and was about to go upstairs when he found Gu Yanan standing on the cobblestone path next to the garden downstairs.

"Yanan? Why are you standing here? It can't be waiting for me, right? Nanhan Fei smiled and approached Gu Yanan.

"Well, I was waiting for you."

"Recently, I have to take care of Uncle Ge, I have lived in the old house for a few days, although we haven't seen each other for a few days, but we talk on the phone every day, so you still miss me?" Nan Hanfei's smile was warm.

"To be serious, I just want to ask about Uncle Ge and his nanny Xiao Song, I called my brother this morning, and he said that Xiao Song has been discharged from the hospital."

"Oh, Xiao Song was discharged from the hospital, or I picked her up and discharged her, she is now living back at Uncle Ge's house, and it is no problem to take care of Uncle Ge, so I rushed back immediately, with you, I still like to live here."

As he spoke, Nan Hanfei held Gu Yanan's hand and prepared to pull her upstairs.

Gu Yanan withdrew his hand, pretending to be serious, but there was a smile hidden in his eyes, "I haven't agreed to be your girlfriend yet." ”

"Huh? Didn't you already say yes? ”

"Nope! When did I say yes? How come I don't remember? ”

"The last time I mentioned this to you, you acquiesced."

"I didn't speak, I didn't agree, I didn't acquiesce."

"Oh, it's okay, I know you've said yes."

While the two were talking, a figure appeared quietly behind them.

"Yanan."

It was a man's voice who spoke, it was Chu Qingfeng, Xiao Chu's brother, whom Gu Yanan had just met a few days ago.

Chu Qingfeng smiled, and after glancing at Nan Hanfei, his gaze fixed on Gu Yanan's face, "Yanan, it's a coincidence, I met you on the first day I moved here." ”

Gu Yanan heard Chu Qingfeng say before that he was going to buy a house in Xinhua Apartment, listening to the tone of his voice now, could he have already bought it? And moved over?

Gu Yanan asked, "You have already moved in?" ”

"Well, I bought 1101, I heard Xiao Chu say that you live in 1201, so I will live downstairs from you, and we will be neighbors in the future, please take care of me."

Chu Qingfeng stretched out his hand with a smile, and Gu Yanan shook it politely, "Welcome new neighbor." ”

Nan Hanfei sensitively realized that Chu Qingfeng's eyes were shining when he looked at Gu Yanan, and the surname of Gu Yanan had been omitted, and he called "Yanan", when did the relationship between the two become so good?

Who is this man? Where did it come from?

Gu Qingcen walked away, and he didn't want anyone else to come.

"Yanan, introduce, who is this?" Without waiting for Nan Hanfei to ask questions, Chu Qingfeng asked Gu Yanan first.

"This is my neighbor Officer Nan Hanfei, and this is Xiao Chu's elder brother - Chu Qingfeng."

"Officer Nan Hanfei? You're also a neighbor of Yanan? Where do you live? ”

“1202。”

"Oh, hello upstairs neighbor, my name is Chu Qingfeng, please take care of me."

"Hello, I'm Nan Hanfei, don't worry, as a friend of Yanan, I will definitely take care of you more in the future."

The two men's hands shook politely for a moment, and the evening breeze blew, and the air seemed to smell of gunpowder.
