"It's a hunting net for birds."

This scene seemed to be expected by Gu Yanan, but Lu Li was very surprised, "These wild birds are protected animals, and there are signs prohibiting catching wild birds everywhere in the scenic area, how can there still be people hunting nets in the forest?" ”

"If everyone can know the law and abide by the law, then what else do law enforcement and supervision departments do?"

Gu Yanan put down the sampling box in his hand and prepared to bring back all the wild birds in the hunting net for testing.

In the hunting net, in addition to the four small gray wild birds that have been dead for a long time, there is also a half-dead one, which flutters occasionally, and should have just been trapped in the hunting net.

Lu Li climbed up the tree, took off the bird hunting net, took off the little wild birds one by one with gloves, sealed them with a sampling bag, and put them in the sampling box.

After Gu Yanan and Lu Li came out of the poplar forest, they went around the Crescent Lake to collect bird droppings, soil and other environmental samples at the gathering place of wild birds.

Lianhai Center for Disease Control and Prevention, Laboratory.

The specimens brought back from Lijia Village and Crescent Lake were tested and the results came out quickly.

The H7N9 avian influenza virus was detected in the nasopharyngeal swab specimen of Li Erzhu's daughter-in-law, Jin Zhi.

The H7N9 avian influenza virus was detected in sick chickens in the chicken coop in Li Erzhu's yard.

The H7N9 avian influenza virus was also detected in a dead bird in a hunting net in a poplar forest near Crescent Lake and in a pile of guano specimens in the southwest corner of Crescent Lake.

Looking at the test results, Lu Li asked Gu Yanan, "Is the avian influenza virus in Li Guoqing's body because of contact with wild birds?" Or is it because of contact with the sick chickens of the neighbor Li Erzhu's family? ”

"It's all possible. But the main thing now is to control the spread of avian influenza viruses. ”

Lu Li thought of the first step in emergency treatment, "to isolate and treat avian influenza patients and close contacts of patients." ”

"Well, these people who notify hospitals and district centers for disease control and prevention to do it."

"The chickens and ducks raised in Lijia Village should also be harmlessly treated, and the entire Lijia Village should also be disinfected."

"Well, this matter will also be handed over to the District Center for Disease Control and Prevention, let Gao Fei go over and guide it."

"The trouble now is that the wild birds around the Crescent Lake also carry the H7N9 avian influenza virus, so you can't kill all the wild birds."

"You can't kill a large number of wild birds, but you can stop people from approaching them, which can also cut off the transmission of the virus." Gu Yanan looked at Zhou Jie sitting at the desk, "Elder Zhou, you are responsible for coordinating with the scenic spot about the wild birds in Crescent Lake, evacuating tourists as soon as possible, and doing a good job of warning signs that 'no contact with wild birds' are allowed." ”

Zhou Jie agreed, "Okay, I've dealt with the Crescent Lake Scenic Area, and I can handle it as soon as possible." ”

Gu Yanan instructed Wang Xiaoxiao again, "The live poultry trading market around Lijia Village should also be investigated, and you are responsible for this." ”

"No problem, just go to the live poultry stalls in the market to collect environmental samples, and there is also a survey of occupationally exposed people in the live poultry trading market, which I am familiar with."

Zhou Jie, Gao Fei, and Wang Xiaoxiao were all sent out by Gu Yanan.

Lu Li couldn't sit still, with such a sudden bird flu epidemic, he always had to do something, "What am I doing?" ”

"Isolate the influenza strain, sequence it, and do genetic evolutionary analysis."

"Huh?" Lu Li was surprised by Gu Yanan's arrangement, "Aren't these things done last?" Why is it in such a hurry? I've always felt that the spread of the virus should be controlled first. ”

"Only by getting the strain and analyzing the genetic evolution of the influenza virus can we figure out the source of the virus and fundamentally control the epidemic."

"Oh, understood!" Lu Li suddenly realized, "I'll isolate the strain now, sequence it, and if it's fast, I'll be able to get the gene sequence before the end of this week." ”

Lu Li returned to the laboratory and got busy again.

In the evening, Gu Yanan received a call from Nan Hanfei.

"The forensic doctor in our team said that we do not have a kit to detect the avian influenza virus, and Jia Daniu's specimen needs to be tested by your disease control and control."

Nan Hanfei's call was expected by Gu Yanan, "Okay, send the specimen, and work overtime tonight to give you the results." ”

Gu Yanan was just about to hang up the phone, but Nan Hanfei suddenly spoke up again, "Wait, Li Erzhu, who was brought back to the police station from Lijia Village today, also had a cold and fever, and I asked the forensic doctor in the team to also take a sample of his nasopharyngeal swab and send it over with Jia Daniu." ”

"Okay, Li Erzhu's daughter-in-law was confirmed to be infected with avian flu, Li Erzhu is a close contact, and is currently a suspected avian flu patient, you should pay attention to protection when you come into contact with him."

"Are you concerned about me?" Nan Hanfei's tone on the phone was smiling.

Gu Yanan has been in the tense atmosphere of the epidemic investigation for the past few days, and now she was infected by Nan Hanfei's words with a smile, her mood was obviously eased, and she also replied with a smile, "I'm worried about the spread of the epidemic, so take good precautions and don't make trouble for me." ”

The smile on the other end of the phone was even stronger, "Okay, I won't trouble you, wait for your news." ”

——

In the evening of the same day, Lianhai City Center for Disease Control and Prevention, laboratory.

The specimens of Jia Daniu and Li Erzhu were quickly sent to the laboratory, and at the same time, the specimens collected by Wang Xiaoxiao from the major live poultry trading markets in Lianhai City were also delivered.

Two batches of specimens began to be tested at the same time, and at 22 o'clock in the evening, the results came out.

The H7N9 avian influenza virus was detected in the human specimen of the deceased Jia Daniu, the nasopharyngeal swab specimen of Li Erzhu, the nasopharyngeal swab specimen of Li Erzhu's daughter-in-law Zhao Jinzhi, and the case board of a chicken slaughter in a live poultry trading market stall in the western suburbs of Lianhai City.

As soon as the results came out, Gu Yanan reported the test results and began to arrange the next work.

Nan Hanfei was first informed of the test results, Li Erzhu was sent to the hospital for isolation and treatment, and the cause of Jia Daniu's death was re-investigated.

The live poultry market in the western suburbs of Lianhai City was temporarily closed for full disinfection.

——

Everything went according to plan, and it has been four days since the first human case of H7N9 avian influenza was detected, Li Guoqing.

In the past four days, the confirmed cases of H7N9 avian influenza, in addition to Li Guoqing, also include Li Erzhu, Zhao Jinzhi and Jia Daniu, who has died.

On the fifth day, the First People's Hospital of Lianhai City suddenly received another suspected avian influenza patient.

The patient's name was Jia Erniu, and he was the younger brother of the deceased cattle thief Jia Daniu.

Jia Erniu fainted at the entrance of Jiajia Village and was taken to the local health center by people from the same village.

Because the human infection with H7N9 avian influenza has been reported to the public, the local health center found a suspected case, immediately isolated the patient, and safely transferred to the city hospital.

The doctor who treated Jia Erniu happened to be Gu Jiashu.

Gu Jiashu heard about the two cattle thieves in Lijia Village next to Crescent Lake from his sister Gu Yanan, and now when he heard Jia Erniu's name, he knew that Jia Erniu was from Jiajia Village, and immediately associated with the cattle thief Jia Daniu.

Jia Erniu's nasopharyngeal swab specimen was sent to the Municipal Center for Disease Control and Prevention, and the test results came out on the same day, H7N9 positive, another confirmed case.

Gu Jiashu gave the avian influenza patient oseltamivir, a special anti-influenza drug, and the patient's symptoms quickly stabilized.

While patients are being treated in hospitals, the CDC laboratory is sequencing influenza viruses isolated from avian influenza patients.

Looking at the influenza virus gene sequence analysis chart on the computer, Gu Yanan frowned slightly.

Lu Li and Wang Xiaoxiao stood beside Gu Yanan and exclaimed:

"The HA gene of the H7N9 avian influenza virus has the highest homology with that of the avian influenza virus among wild birds in neighboring Z province of Lianhai City."

"Could it be that this H7N9 avian influenza outbreak was transmitted from wild birds in Province Z?"
