Wang Xiaoxiao used her gloved fingers to gently wipe the mushroom bag, and a thick layer of white powder immediately stuck to her fingers, which was thicker than the mushroom bucket in Yuan Jian's national kitchen.

Gu Yanan checked the two fungus packets, and then looked down at the ground, where there was also a layer of white powder on the floor of the greenhouse, and footprints were made where people passed.

Gu Yanan used a cotton swab to take samples of the fungus bag and the white powder on the ground, and then gave an order to the CDC group, "Leave here first and go to the greenhouse of Yuan Dashan and Yuan Xiaoshan's house." ”

The greenhouses of the three families are very close, out of the greenhouse of Yuan Jianguo, followed by the eldest son Yuan Dashan's family, the scale is larger than the greenhouse operated by Yuan Jianguo, and the mushrooms are also planted in the shed, and the variety of mushrooms is oyster mushroom.

The oyster mushrooms on the mushroom bag are dense, and there is also a layer of white powder on the floor of the greenhouse.

Gu Yanan let Wang Xiaoxiao take a sample, and then went to the greenhouse of his youngest son Yuan Xiaoshan's house next door.

The third greenhouse is slightly smaller than the previous two, but there are more types of mushrooms planted in it, such as lion's mane, oyster mushroom, and reishi......

Gu Yanan's attention was still on the floor of the greenhouse, and he found that there was also a thin layer of white powder here.

Walking out of the last greenhouse, Gu Yanan's eyes were more certain, and he asked the village chief who was following him, "Are there any other mushrooms in the village?" ”

"No, Yuan Jianguo and his two sons grow mushrooms, and the other families grow vegetables such as cucumbers, tomatoes, eggplants, and melons, as well as small fruits such as strawberries."

Gu Yanan instructed the village chief, "In the future, remember to wear a mask in the mushroom greenhouse." ”

"Wearing a mask? Why? Is there really a contagion in this? ”

"There are no infectious diseases, but there are occupational diseases."

The village chief looked puzzled, Gu Yanan continued to explain, "After the mushroom matures, it will produce a large number of mushroom spores, the spores are very small and can be dispersed in the air, people inhale the spores into the lungs, deposit them in the alveoli, form immune complexes, and produce allergic reactions, and the corresponding symptoms produced by humans are chest tightness and wheezing, upper respiratory tract symptoms, coughing, sneezing and runny nose, which may become thick nasal discharge after clearing the nose at first, bloody sputum in severe cases, and then pneumonia in more serious cases, as well as other organ lesions. ”

Although the village chief didn't know much about the technical terms, he knew that he would get sick if he didn't wear a mask to enter the greenhouse where the mushrooms were grown, and that was enough.

The village chief nodded repeatedly, "Okay, I'll inform the other villagers to pay attention." ”

On the way back to the disease control from Yuanjia Village, Gu Yanan sat in the co-pilot position of the shunting car and called his brother Gu Jiashu.

"Brother, Yuan Jianguo and his two sons grow mushrooms in the greenhouse at home, and I suspect that Yuan Jianguo's family may be mushroom lungs."

Gu Jiashu was not surprised, "I just performed a chest puncture lung biopsy on the patient, and the results showed that there were diffuse interstitial lesions in both lungs, chronic inflammation in the lung tissue, fibrous tissue hyperplasia, alveolar interval widening, scattered chronic inflammatory cell infiltration, and alveolar epithelial hyperplasia, which are all indications of allergic alveolitis.

I was wondering what he was allergic to, and it turned out to be mushroom spore deposits.

I looked at Yuan Jianguo's medical records before, although he was running a greenhouse, but it was written that he mainly planted vegetables and tomatoes, and I didn't think about mushrooms. ”

Gu Yanan: "The source of pneumonia of unknown cause has been found this time, and it is mushroom spores. Infectious diseases become occupational diseases, and the isolation measures of hospitals can be lifted, and the knowledge of occupational disease protection must be kept up with patients. ”

Lianhai Center for Disease Control and Prevention, Emergency Office.

Gu Yanan is writing a summary report on the mushroom lung epidemic in Yuanjia Village.

Yuan Jianguo, a villager in Yuanjia Village, Qixia County, at the southern end of the Qingcheng Mountains, grows mushrooms in a greenhouse.

Mushrooms enter the ripening stage, producing a large number of mushroom spores.

The mushroom spores were dispersed in the air in the greenhouse, and Yuan Jianguo's family entered the greenhouse to work, inhaling a large number of spores in the process.

The spores are deposited in the alveoli and cause an immune response in the body, causing symptoms of the upper respiratory tract and pneumonia.

The mushroom spores of the pathogenic source were found, the possibility of viral pneumonia was ruled out, and the diagnosis of mushroom lung was diagnosed.

The patient gradually recovers with anti-inflammatory and anti-allergic treatments.

After writing the summary report, Gu Yanan filed the report.

Wang Xiaoxiao copied a summary report of the mushroom lung epidemic, and sighed after reading it, "The cause of pneumonia of unknown cause this time turned out to be mushroom spores, I thought it was an infectious disease epidemic, but I didn't expect it to be an occupational disease." ”

Lu Li sat at his desk, with an umbrella cap and a small mushroom fully open in the small succulent flower pot on the table.

This was brought by Wang Xiaoxiao when she was sampling in the greenhouse of Yuan Jianguo's house, and she was going to throw it away, but Lu Li picked it up and put it in a small flower pot on her desk.

Lu Li stared at the little mushrooms in the flower pot, and picked up Wang Xiaoxiao's words just now, "There are really many kinds of occupational diseases now, no matter what you do, there will be occupational diseases, such as mine workers may get pneumoconiosis, coating workers may get metal heat, people who grow greenhouses may be allergic to pesticides and crops, mushroom lung is one of them, even those who sit in the office may get cervical and lumbar spondylosis, what do you say we are most likely to get from occupational diseases?" ”

Xiao Chu: "We may get more diseases, and we may get any diseases when we come into contact with them, thinking about the epidemic of infectious diseases that our CDC usually handles, there are too many possibilities." ”

Wang Xiaoxiao looked at the little mushroom that Lu Li picked up and quipped: "If you don't throw this little mushroom away, you may also get mushroom lungs." ”

"Impossible." Of course, Lu Li didn't believe it, "If you can get mushroom lungs with only this one, then you planted so many on the balcony at home before, wouldn't you be sick early?" ”

Wang Xiaoxiao: "This has something to do with personal physique, there are so many kinds of mushroom farmers in the country, not everyone gets sick, Yuan Jianguo's family will get mushroom lungs, in addition to the poor ventilation in their greenhouses, the mushroom spores in the shed exceed the standard, but also related to their personal physique." ”

Speaking of this, Gu Yanan thought that there are still many mushrooms grown in greenhouses like Yuanjia Village in Lianhai City, and they need to do a good job of occupational protection, so they instructed Lu Li, "Lu Li, you write a tweet about the occupational protection of mushroom lungs, hang it on our website, and transfer this tweet to various counties and districts for disease control and control, so that they can do a good job in publicizing mushroom growers in their jurisdiction." ”

"Okay."

In the evening of the same day.

Lianhai City, Xinhua Apartment.

Gu Yanan walked on the road of the bachelor apartment after work, and before he entered the community, he found a familiar figure in the garden of the community.

Xiao Chu was talking to a strange man.

The man was half a head taller than Xiao Chu, of medium build, and was wearing a sportswear, because his back was facing the light, and he couldn't see his face clearly.

The two first talked, and then the voices became louder and louder, like a quarrel, and then Xiao Chu wanted to leave, but the strange man took Xiao Chu's hand, and the two argued.

Xiao Chu was restrained by a strange man and couldn't move.

When Gu Yanan saw this, he was immediately furious, how could he let his team members be bullied by others?

Within three seconds, Gu Yanan rushed forward, and an over-the-shoulder fall threw the strange man on the grass in the garden.
