Xiao Chu wrote on the flow chart:

Occupation: Farmer

Professional environment: greenhouse, growing vegetables, the main vegetable species tomatoes.

Lu Li asked Yuan Jianguo again, "When did you start feeling unwell?" ”

"It's been a long time."

Lu thought that when doing the flow survey, he was most afraid that the patient would answer such vague questions, which would not make sense to speculate on the etiology.

The exact time is uncertain, and this long time may be a month or half a year.

"How long is a long time? Can you determine the exact number of days? ”

Yuan Jianguo tried to recall, and his wife Li Jinhua said on the side: "I know this, my old man has been coughing intermittently since autumn, and the weather has become cold recently, especially after the snow, the cough has become more serious." ”

Coughing since fall? It's been too long, and it's not a symptom of the flu.

Lu Wei thought, could it be that the cause of Yuan Jianguo's family's pneumonia was not the flu?

Lu Li asked Yuan Dashan and Yuan Xiaoshan the same question in the adjacent hospital bed.

Yuan Dashan: "I'm similar to my dad, I also started coughing in the autumn, and it has become worse recently. ”

Yuan Xiaoshan: "Me too." ”

Speaking of their respective conditions, Yuan Dashan's daughter-in-law took the initiative to react to Lu Li, "Doctor, I also have a cough and runny nose, but I didn't start it in autumn, I only started after the recent snowfall."

Doctor, am I infected? Will it get worse and worse like my father-in-law and husband? ”

Lu Li is also most afraid of patients asking such questions, and he cannot give any definite answers without the support of laboratory results and field flow data.

Lu Li shook his head, "I will take samples for you in a while, and when the results come out from the laboratory, our CDC will give feedback to your attending doctor." ”

Lu Li asked Yuan Dashan, Yuan Xiaoshan and their families some questions, and then took samples, ended the basic flow and left the hospital.

On the way back to the CDC laboratory from the hospital, Lu Li sighed while driving, "When Sister Yanan showed me the medical records of three patients before, I said why I always felt that Yuanjia Village was so familiar, it turned out to be a civilized greenhouse village out of the city." ”

Xiao Chu was a little absent-minded along the way, and Lu Li saw that he didn't talk, and asked: "Xiao Chu, did you encounter something?" I've been stunned since this morning. ”

"Oh...... It's okay. Xiao Chu hurriedly returned to the topic just now and agreed, "Last time, we went to Yuanjia Village to investigate a collective poisoning incident caused by fresh white fungus, and I still remember that the pathogen was Pseudomonas coconut, and that time I also ate candy from Yuanjia Village. ”

"I've also eaten their candy, I hope Yuan Jianguo's family will be okay this time." Lu Li said this, but he felt bad in his heart, and he always felt that something was wrong.

Lianhai Center for Disease Control and Prevention, Laboratory.

Lu Li took Xiao Chu to send the specimens collected from the hospital to the laboratory, and after Xiao Zhang received the sample, his face was tired and slightly complaining.

Lu Li rarely saw Xiao Zhang's expression, and couldn't help asking, "Who offended our handsome guy Zhang?" What's this expression? ”

While counting the specimens and signing, Xiao Zhang complained, "Recently, there has been a flu outbreak, and the machine is spinning, and several people in our laboratory have been working overtime for several days, so tired, I really hope that the flu epidemic will pass soon." ”

Originally, I complained about the overwork, but the recent flu outbreak is indeed a lot more than in previous years, and it is not easy for the laboratory to produce results on time and in the case of insufficient manpower.

Lu Li patted Xiao Zhang's shoulder and comforted: "It's hard work, when I'm done with the emergency team, I'll come and help you." ”

Xiao Zhang smiled bitterly, "You're here to help me?" It's not that I'm talking about you, the respiratory epidemic has been particularly serious recently, and you may work overtime even worse than me. ”

"Bah, bad spirits, don't curse me." Lu Li knew that Xiao Zhang was known as a crow's mouth, and every time he said that there was an epidemic, something bad would definitely happen in a while.

Xiao Zhang pursed his lips and put away the specimen, "I take back what I just said, my current wish is: world peace, everyone is healthy, and there is no disease in the world." ”

"It's a bit difficult, I make a realistic wish, I hope these specimens can be on time in two hours."

Xiao Zhang made an OK gesture, "The god of lights fulfills your wish." ”

"Thank you, the god of lights."

Two hours later, the results of the experiment came back.

No influenza virus was detected in the body fluid samples of Yuan Jianguo, his two sons and their accompanying family members.

The cause of Yuan Jianguo's family's pneumonia was not influenza virus infection.

Lu Li got the experimental results and reported them to Gu Yanan as soon as possible, and Gu Yanan immediately asked the laboratory to test for several other common pathogens in the upper respiratory tract.

Nine tests for respiratory tract and several other uncommon respiratory pathogens were screened until the laboratory reported results on the morning of the second day, and all tests were negative.

Yuan Jianguo's family's pneumonia was initially presumed to be infected by the influenza virus, to pneumonia of unknown cause.

Judging from the current situation, this time there is a family cluster of pneumonia cases of unknown cause, and it is likely to be highly contagious, although there are no deaths so far, but judging from Yuan Jianguo's symptoms, the situation is not optimistic.

Gu Yanan immediately reported the situation to the hospital and contacted the attending doctor Gu Jiashu.

Gu Jiashu: "Little sister, do you want me to upgrade the isolation level of the patient?" ”

"Well, I think it is necessary to upgrade the isolation level, at present, the cause of Yuan Jianguo's family has not been detected, it cannot be ruled out that they were infected by highly pathogenic pathogens, they are likely to infect the people around them as the source of infection, and the protection of medical staff is also very important, think about SARS back then."

During the SARS epidemic that year, many medical staff were infected because they had direct contact with patients without protective measures, resulting in the death of many medical staff.

"I understand, I will make arrangements in accordance with the isolation measures of SARS patients back then, how do you plan to investigate the pathogen of Yuan Jianguo's family this time."

"As before, go to Yuan Jianguo's house to conduct on-site investigation."

Yuanjia Village, Qixia County, Lianhai City.

At the entrance of Yuanjia Village, the staff of the Qixia County Disease Control and Prevention Field Department met with the Lu Li, Xiao Chu and Wang Xiaoxiao emergency team led by Gu Yanan.

Section Chief Qian is fully armed, and his biosafety protective suit is very eye-catching.

The other staff of the county CDC except for Section Chief Qian were also wearing protective clothing, and Wang Xiaoxiao saw it and muttered quietly, "The level of this protective clothing is a bit high." ”

Lu Li got out of the car and followed Wang Xiaoxiao's side, "The villagers don't recognize the type of protective clothing, no matter which one we wear, as soon as we appear, the villagers will panic." ”

Gu Yanan also put on protective clothing, "Proper panic is not a bad thing. ”

Xiao Chu echoed on the side: "Vigilance is a kind of appropriate panic, our appearance means that there may be infectious diseases here, the villagers will be vigilant, and then they will be ready to take precautions." ”
