"Due to the recent outbreak of new Legionella pneumonia in our city, martial law will be implemented throughout the city at 19:00 on the evening of August 3. Please return home as soon as possible, do not panic and wait patiently for the evacuation arrangements......"

On the TV screen, the male host's expression is very serious, his voice is solemn and generous, full of confidence to overcome difficulties.

Shanhai City, no matter which TV channel you turn on, the signal is this breaking news report.

The internet has been banned, but mobile phones across the city are receiving such SMS notifications, and every once in a while there is a new one.

From 2 p.m. to 7 p.m., martial law was imposed, and the time was so hurried that people were both surprised and frightened.

Some people immediately wanted to leave Shanhai City by car, whether they were from other places or local people with their families, but they all found that all the entrances and exits had been controlled and the whole city was closed.

Some people want to go to the supermarket to grab shopping materials, but find that all supermarkets and large shopping malls are blocked and cannot enter.

In the news report, the host actually made it very clear.

Legionella bacteria are airborne and occur in the natural environment in artificial water supply systems such as air conditioning and refrigeration systems, hot and cold water systems, etc. These systems excrete contaminated aerosols, which can become infected when inhaled, causing symptoms such as fever, sweating, difficulty breathing, and coughing.

Therefore, places like supermarkets, gymnasiums are the places where the transmission is most severe.

All air conditioners in the city should not be turned on immediately, showers, humidifiers, etc. should also be deactivated, and all artificial water supply systems should be deactivated, and the city's water supply will be shut down from 0:00 on the 4th. Please store water, but it is best not to drink, if you want to drink, you have to leave it for ten hours, do not approach the tap if there is water, please hold on until evacuation, do not panic.

Prevention and control personnel will first take away the infected and suspected infected people in the city for quarantine one by one, and then evacuate other people.

"Please be patient and stay home." The moderator repeatedly emphasized, "Don't panic. ”

This press release is clearly deliberate to make the public understand the seriousness of the situation without panicking, and it does not even say "outbreak" but "emergence" of the epidemic.

People who study medicine hear more strange things, the contagiousness of Legionella bacteria in the past was not so powerful, what does "new Legionella" mean?

Not everyone knows about Legionella, but everyone can feel the severity of these emergency measures.

Li Mingqiu graduated from university for six years, is nearly 30 years old, and is a programmer in an IT company.

As soon as the citywide notice came out in the afternoon, people in the company panicked, and everyone wanted to leave immediately, but the leaders said that the guidance document told them to stay in the company as much as possible and wait for evacuation, and it was those who walked on the street who wanted to return home as soon as possible.

"If you have children to take care of, you can go first. Others think about it for themselves, the traffic outside is very chaotic, and there are many people, so it is easier to get infected when you go out and run around. ”

Truth be told, looking out of the window on the middle floor of this office building, the streets are crowded with pedestrians, taxis simply don't stop, and they are on the verge of traffic paralysis.

Because Li Mingqiu was not a local, he was not married and had no children, so he shared an apartment with others, and it was not good to go back, so he chose to stay in the company.

Half of the colleagues stayed, not all because of their families, but also because they wanted to grab shopping materials: "I don't know how long I have to wait for the evacuation, this germ can contaminate the water, and the mineral water will be robbed later." Some people think it's not a big deal at all: "It's just a scare thing, a routine." ”

The central air conditioning was turned off immediately, and in this hot summer of August, the office was immediately hot, and the windows had to be closed according to the instructions.

"This outbreak may be more serious than SARS......

"Yes, the state must have known that it was hasty, but it did it anyway."

The office was stuffy, and the dozen or so people left stayed in their seats, and after the initial excited discussion, they were already at a loss to say that there was no match.

At this time, Wei Xiaoru, who was chatting with a doctor classmate on the phone, put down the phone and sighed to the nervous crowd: "My classmate said that there are many kinds of Legionella bacteria, and this time it should be a new bacteria, which is different from the previous ones." To prevent Legionella bacteria, open windows to keep them ventilated and not provide them with an ideal environment to grow. ”

"And we're going to close the window?" Zhang Dawei exclaimed, this is also the doubt of Li Mingqiu and others.

Wei Xiaoru recalled: "The main vector of Legionella bacteria is the aerosol mentioned in the news, but it can generally only spread with the wind to a radius of 200 meters and survive in tap water for more than an hour. Now we have to close the windows and stop the water, and my classmate said that there are only three possibilities. ”

"One is that this new type of Legionella has more diverse vectors, a larger range of transmission, and a longer survival time in water; Second, the CDC believes that Shanhai City has been ...... everywhere It's all contaminated. Also, the first two may be true. ”

Everyone looked at each other, and although they didn't know much about medicine, they all understood how serious this was.

Spread with the wind? Spread with tap water? People always have to breathe and drink.

"The whole city is polluted?" Zhang Dawei's face was full of anger, "How did you do it, did you hide it, and you have to evacuate after you do this?" ”

"My classmate said......" Wei Xiaoru was also at a loss, "this epidemic may develop very quickly, and even the country is caught off guard." ”

Everyone was worried and anxious, but they could only wait, and at seven o'clock in the evening, the sirens sounded over the city, and martial law began.

They looked out of the office window and the streets had long been silent, except for disease control vehicles and martial law vehicles that had appeared since the afternoon on the road from time to time, and a team of disease control personnel wearing white protective suits walked by, grabbing individual people who were still wandering outside into transport trucks and taking them away.

But it has long been said in the news that there is a greater risk of infection if you come into contact with disease control personnel, so don't deliberately go out and get arrested.

Moreover, they were not taken away from Shanhai City, but were taken for examination, and once they were suspected of being infected, they would be isolated and treated.

After the siren, another radio sounded over the city: "Please return home as soon as possible......

The news also said that if you notice that someone around you is having suspected symptoms such as coughing, please stay away from the suspected patient immediately and call the helpline. If you have symptoms, call the hotline immediately to get treatment as soon as possible.

Why evacuate patients first and then others?

Li Mingqiu pondered this problem for an afternoon, and the more he thought about it, the more he felt that in addition to the lack of manpower, it should be that the entire Shanhai City was polluted......

The disease has an incubation period, and whoever carries the germs and who doesn't have it, can't see it, and one patient can expand the scope of contamination and infect thousands of other people.

Therefore, it is necessary to use time to let the patients themselves reveal it first, so as to determine where Shanhai City is still clean.

Perhaps only healthy people in clean areas will actually be evacuated in the end......

Everyone was silent, and suddenly at this time, Lin Mingda, a colleague who was sitting in his office chair and didn't talk much, coughed violently: "Cough, cough ......."

All of a sudden, they all turned their heads to look, only to see that Lin Mingda's face didn't know when it had become, and it became a little ugly.

It's over, Li Mingqiu's heart tightened, and his whole body seemed to collapse, and Wei Xiaoru next to him also turned pale.

"Ahh Zhang Dawei took a few steps back, and said in a panic: "Call someone, call quickly......"

"I, I ......" Lin Mingda wanted to say something, but he only coughed more violently: "I, cough cough ......"
