"Ahem, ahem......"

The night was hazy, and the sound of coughing continued to come from the various wards, echoing in the corridors of the inpatient department.

The facilities of the town hospital are simple, and the isolation ward where Shen Haoxuan is located is not a real isolation ward, but an ordinary ward.

Of the three beds, two of which were vacant, he lay on one of them, with a needle stuck in the back of his hand and a few bottles of intravenous drip. There is no TV in the ward, but fortunately his mobile phone has not been taken away, and the network signal is okay, so he can still play with his mobile phone to relieve his boredom.

Shen Haoxuan pressed his mobile phone with both hands and sent a message to his friend Liu Hui on WeChat:

"Really unlucky, pneumonia, quarantined."

"I was going to go to the general ward, but the doctor suddenly said that I needed to be isolated, and even my parents were quarantined."

"It must be the uncle on the bus who infected me, I may have to live in the hospital for several days, I hope to catch the comic convention in the city on Saturday, helpless"

After a while, Liu Hui didn't reply.

Shen Haoxuan's cough became more and more uncomfortable, and he had been on the drip for more than half an hour, and the fever didn't seem to have subsided, and the cough was getting worse......

He checked the circle of friends posted by Deng Nuotong again: "The next stop is Shenshi University, thank you for the past, look forward to the future, come on!" ”

"Hehe, cough ......" Shen Haoxuan couldn't help but smile when he looked at it, feeling that his body was much better. I used to look forward to a few more days of summer vacation, but now I look forward to the start of the university as soon as possible. At this time, the mobile phone received a shock from WeChat, and when he saw it, it was sent by Liu Hui:

"Oops, I started coughing in the evening and now I have a fever of 39 degrees"

"Maybe you're infected, pneumonia? Isn't it?"

"My mom got me cold medicine to take, do you want to go to the hospital now?"

Looking at these messages, Shen Haoxuan felt sorry for his friend, and muttered uneasily, am I infected? Besides Liu Hui, there won't be anyone else, right?

He thought of his parents, his friends, and so many people at the comic con......

Don't think about it. Shen Haoxuan coughed and told himself, how could there be such a bad infection, and SARS would not be.

It's just pneumonia, the doctor can fix it, and it should be well after a few days in the hospital.

Shen Haoxuan pressed his mobile phone and replied: "Come to the hospital to see, blame me, when we are ready, I will treat you to a meal"

……

The thirtieth, the fortieth, and the fiftieth.

If it weren't for the fact that Jiangxing Town Hospital usually does not have so many patients and a large number of vacant wards, it would not have been able to cope with the outbreak of the epidemic tonight. But each patient has to be isolated individually, and there are still not enough wards. Everyone who was still in the hospital was busy during the night.

The CDC has ordered the town to lock down the hospital, and suspected infected patients can come in, but no one can leave here.

"Hey, Xiao Lin, you should pay attention to the tenth patient when it appears."

Zhao Yutao changed his tone, he was already wearing a triple mask, and from time to time he looked for opportunities to sneak out of the emergency room, not wanting to come into contact with patients.

Huang Lin ignored him, although he also wore multiple masks, he stuck to the emergency room, and took the time to call his classmates and teachers in the university to ask for his opinion.

The teacher gave her an idea, could it be "Legionella pneumonia"?

Not to mention town-level hospitals, even in tertiary hospitals, Legionnaires' disease is often misdiagnosed as ordinary pneumonia first. Because it is not a common disease, it is often unrecognized by general practitioners, and the clinical manifestations of Legionnaires' disease are complex, and routine tests lack specificity, and serologic testing for Legionella antibodies can only be confirmed.

"Legionnaires' disease." Huang Lin read some literature on the Internet, and it was somewhat similar, but not all, and the patient's condition developed too quickly.

And some of the news made her extremely uneasy, and there were outbreaks of Legionnaires' disease in many cities around the world a while ago.

Huang Lin immediately reported this possibility to the people in the hospital's infectious disease department, only to learn that a few days earlier, the disease control had a prevention and control document to convey that you should be careful of Legionnaires' disease. But the prevention and control documents are always coming one after another, the prevention and control work has been done, and the hospital's air-conditioning and refrigeration system has been cleaned.

Legionnaires' disease often breeds and outbreaks in hospitals, but the last time the first patient, Wang Xin, came to the hospital several years ago, not in the hospital.

At 21:45 in the evening, an hour and ten minutes after the report, the expert group sent by the Municipal Disease Control and Prevention to do epidemiological investigation arrived.

The hospital infectious disease department and medical staff who greeted them in the hospital lobby were stunned, only to see that the team leader He Fenghe, deputy team leader Li Wen and the other two were wearing a set of full-body white protective clothing and full-scale respiratory protection, and their skin was not exposed at all.

Then everyone in the emergency room also saw it, and Zhao Yutao hurriedly put on two more masks.

Huang Lin was already mentally prepared, and the people in disease control also suspected that the legion was sick, and it was spread through the air......

After getting acquainted, He Feng and others talked with Huang Lin about the patient's situation and walked to the isolation ward. They went to see Wang Guoxin first, his condition continued to deteriorate, he was already showing symptoms of confusion, and he had just coughed up a large mass of bloody sputum, and the strong smell of blood and rancid smell filled the ward.

"None of this medical waste can be treated normally." He Feng specially instructed the people in the hospital's infectious disease department.

After seeing several patients, especially Shen Haoxuan, he was sure that it was an epidemic outbreak.

"Comic Con?"

After Shen Haoxuan was infected, he participated in a comic exhibition with more than 3,000 visitors, which made He Feng and them feel uncomfortable for a while.

He Feng hurriedly made several phone calls, asking the CDC to take it seriously, upgrade the epidemic control work, and apply for a temporary control lockdown on Jiangxing Town.

But he knew that the time was too rushed, there were too few test results to support, and it was a big night, so it would not be very efficient. If it weren't for the recent outbreak of Legionnaires' disease in the world, and the bigger ones had documents coming down, his words would have been immediately replied.

Now because he reported it as suspected Legionnaires' disease, and Huang Lin, the doctor on duty, also had this opinion, the disease control and various departments are still nervous.

Is it Legionnaires' disease? Or is it some other pneumonia?

It is too late to take the serum for an antibody test, and it takes a week or two for the patient to produce antibodies in the body; And the town hospital is doing a longer bacterial culture.

However, in recent years, nucleic acid amplification technology has matured, and the cognition of microorganisms has shifted from external structural characteristics to internal genetic structural characteristics, and the detection has also shifted from biochemical and immune methods to gene-level detection. Initial testing can be quickly completed with PCR technology, which can effectively respond to such public health emergencies.

However, the town hospital has limited conditions and does not have a PCR laboratory. Either ship the sample out or bring the equipment in.

As early as on the way here, He Feng applied to transport PCR equipment into Jiangxing Town.

It was also because of the importance attached to the Legionnaires' disease that he quickly approved his request.

In the early hours of the morning, a batch of instruments and equipment finally arrived at the town hospital, along with a group of testing technicians, all wearing protective clothing. After setting up PCR equipment in a small laboratory in the hospital, the group immediately used 22 respiratory pathogen nucleic acid detection kits for rapid screening.

Whether it is epidemic virus, parainfluenza virus, coronavirus, Legionella pneumophila, Mycoplasma pneumoniae, etc., it can be detected by its DNA.

It was also at this time that Li Wen, who was in charge of guiding the medical prescription, hurriedly walked into the laboratory, and his face under the respiratory mask was ugly.

"What's wrong?" He Feng asked, knowing that something was wrong in his heart.

"Dr. Huang Lin has a cough." Li Wenhan said, "Another doctor Zhao Yutao and several nurses in the emergency department also showed symptoms. ”

He Feng's brows suddenly furrowed...... Dr. Huang Lin has only been on duty for 6 hours since he started his shift, which is much shorter than the average incubation period of 36 hours for non-pneumonic Legionnaires' disease......

This whole hospital is an epidemic area.

Although PCR technology is fast, it is relatively speaking, from the early morning to the next morning, everyone in the laboratory is busy and waiting.

Not a virus, not a streptococcus, not chlamydia......

Legionella pneumophila! The DNA structure suggests that this is a new type of Legionella.

As soon as the test results came out, He Feng, who had not slept all night, was a little happy. The pathogen is known, and although the onset is rapid and the disease progresses rapidly, the epidemic should be calmed down by treating and controlling Legionnaires' disease. Although Legionella bacteria can be airborne, it relies heavily on aerosols as carriers......

Just when He Feng was feeling lucky, without warning, because of the sudden strange sensation in his throat, he coughed suddenly, and his lungs were stuffy.

For a moment, He Feng stood in this small laboratory, his face was pale, and he was a little spinning. The surrounding experimenters were all stunned.

"Level 3 protective clothing doesn't work, Level 3 protective clothing doesn't work......"

He Feng muttered blankly, and suddenly burst out with a string of coughs, and at the same time, the sorrow and panic that gushed out made him fall to the ground almost all at once.

Human-to-human, airborne.

The contagiousness can penetrate the level 3 protective suit......

Most of the visitors to the comic exhibition that Shen Haoxuan participated in were probably infected.

The entire town of Jiangxing is an epidemic area.

The entire Shanhai City is an epidemic area......
