According to Gu Yanan's previous experience in on-site epidemiological investigation, he determined that Li Guoqing's wife had concealed it.

Gu Yanan accentuated, "Are you sure?" ”

Li Guoqing's wife had something in her heart and didn't dare to nod.

Gu Yanan took advantage of the situation and asked, "Where Li Guoqing contracted the avian flu is very important, if there is concealment or omission, it will cause his relatives around him to continue to be infected." ”

Li Guoqing's wife was obviously panicked, and stammered: "My family's National Day is to occasionally catch some wild birds and come back." ”

"Where did you catch the wild birds?"

"Around Crescent Lake."

Gu Jiashu, who was standing on the side, heard this, and couldn't help but say: "Crescent Lake is a famous scenic spot in our city, and all kinds of wild birds in it are protected animals......"

Without waiting for Gu Jiashu to finish speaking, Gu Yanan glanced at him, and Gu Jiashu immediately shut up.

Gu Yanan continued to ask Li Guoqing's wife, "When was the last time Li Guoqing went to catch wild birds around Crescent Lake?" ”

"About a week ago, I caught two of them and I cooked them into soup and ate them."

The more Li Guoqing's wife spoke, the more frightened she became, "Doctor, my husband and I ate both of my wild birds, and my husband has bird flu, so I won't get bird flu too, right?" I've also had a sore throat for the past two days. ”

Gu Yanan glanced at Gu Jiashu, then turned to Li Guoqing's wife and instructed, "The doctor will give you a sample and examination in a while, but you will be quarantined and observed for the next few days." ”

"Why did the doctor isolate me? Aren't my test results still out yet? Not sure I have bird flu. ”

"Because Li Guoqing has been confirmed to be infected with the H7N9 avian influenza virus, people who have been in contact with Li Guoqing must be quarantined and observed."

"Huh?!" Li Guoqing's wife exclaimed, "Fortunately, my son lives in school and has not been at home recently." ”

Gu Yanan continued to ask: "I want to know who Li Guoqing has been in contact with in the past 7 days, and I want a detailed list. ”

"My family lives in Lijia Village, next to Crescent Lake in the suburbs, and they usually work in the fields, rarely contact outsiders, and don't visit the door much, but they will work in the fields or talk to neighbors on the way home."

"I read Li Guoqing's medical records, and before he was transferred to the First People's Hospital of Lianhai City, he had been treated in a suburban medical center."

"Well, I had a fever reduction bottle at a suburban medical center, and I came into contact with the doctors and nurses there."

Gu Yanan asked some more questions, and after figuring out the matter, Gu Yanan left the infection department and began to use the phone to assign tasks to the people in the emergency response office on the road.

Zhou Lao and Gao Fei went to the suburban medical center to investigate the list of doctors and nurses that Li Guoqing had come into contact with during his treatment, and put them under quarantine observation.

Gu Yanan and Lu left the on-site flow shunting of the CDC and went to Lijia Village, where Li Guoqing is located, to conduct on-site flow investigation.

——

The suburbs of Lianhai City, Lijia Village next to Crescent Lake.

The CDC's on-site shunting car stopped at the entrance of Lijiacun Village.

Gu Yanan and Lu Li got out of the car, carried the sampling box, and walked along the village road in the direction of Li Guoqing's house.

The two asked for directions as they walked, and finally found Li Guoqing's home under the guidance of the villagers.

At the east end of the village, there are four large tiled houses with a courtyard, white courtyard walls, painted red wooden doors, and a grapevine and two moon trees planted in the flower garden next to the door.

Gu Yanan used the courtyard door key given to her by Li Guoqing's wife to open the lock on the red lacquered door and enter the small courtyard of Li Guoqing's house.

Li Guoqing's home was inspected and samples were taken of items he might have touched.

After that, Gu Yanan planned to go to the neighbor's house on National Day to check.

Li Guoqing's wife once told Gu Yanan that Li Guoqing had come into contact with chickens from his next-door neighbor's house before he became ill.

This is a very important clue.

Gu Yanan and Lu Li came out of Li Guoqing's house and arrived at the door of Li Erzhu's house next door, but they heard a commotion in Li Erzhu's house.

Soon, several plainclothes policemen walked out of the courtyard of Li Erzhu's house, led by people Gu Yanan knew.

Nan Hanfei and a team of policemen, with an old man with handcuffs in his hands, were preparing to get into the police car.

Nan Hanfei and Gu Yanan took a look, and both of them were stunned.

Nan Hanfei saw Gu Yanan dressed in bioprotective equipment and asked, "There is an epidemic here?" ”

"The head of the household next door is infected with the H7N9 avian influenza virus, and we are here for an epidemiological investigation, and you are ...... here?"

Nan Hanfei pointed to the cordon around Li Erzhu's house, "There was a murder, take the suspect back to investigate." ”

Lu Li followed Gu Yanan and asked softly, "Dead?!" ”

Since Gu Yanan's disease control team and the police team led by Nan Hanfei practiced boxing and kicking together, people on both sides are very familiar, at this time, Xiao Li, a policeman who was holding an old man in handcuffs, interjected: "This family killed a cattle thief, we are here to arrest someone." ”

Nan Hanfei glared at policeman Xiao Li, "As a policeman, we can't talk nonsense until the matter is investigated, we just take the suspect back to cooperate with the investigation." ”

Lu Li didn't care about who died or why, he only cared about the cordon pulled up by the police in front of Li Erzhu's house, which hindered the on-site flow of disease control.

Lu Li pointed to the yellow warning belt, "We're going to go in and take samples, these warning belts?" ”

Nan Hanfei immediately explained to Gu Yanan: "The evidence collection has been completed on the spot, and the cordon will be withdrawn in a while, you can go in." ”

Gu Yanan was about to go inside, but Nan Hanfei stepped forward again, "Yanan, there are only two of you, I'll help you...... Busy with your business. ”

"No, you don't." Gu Yanan refused.

A hint of loss flashed across Nan Hanfei's face.

Gu Yanan pointed to the biosafety protective clothing on his body and explained: "The sampling task of on-site flow investigation is dangerous, and you don't have protective equipment, so it is not appropriate to stay here." ”

Nan Hanfei was relieved, "Okay, then let's take people away first, if you have any investigation results, remember to tell me, bird flu, it sounds quite scary." ”

"Hmm."

Nan Hanfei and his entourage first removed the cordon around Li Erzhu's house, and then drove away with the suspect in a police car.

Originally, because Li Erzhu was taken away by the police, Li Erzhu's family was already in a state of shock, but now they saw that the disease control personnel wearing protective equipment were going to come in to investigate, and the family was even more panicked.

Gu Yanan gave a simple explanation to Li Erzhu's family and entered the small courtyard.

An old woman, who is Li Erzhu's wife and Li Jianguo's mother, was worried about what his wife would do at the police station, so she hurriedly instructed her son: "Come and take a look, take care of your father, just have me and your daughter-in-law Jin Zhi at home." ”

Li Jianguo drove his own tricycle and followed the police car to the urban police station.

In the small courtyard of Li Erzhu's house, his daughter-in-law Jin Zhi took the initiative to say to Gu Yanan and Lu Li: "If you want to investigate, just check." ”

Lu Li took nasopharyngeal samples from Li Erzhu's family and prepared to go back to test their nasopharyngeal swab specimens to see if they were also infected with the avian influenza virus.

Gu Yanan found the chicken coop on the side of Li Erzhu's yard.
