Natural disaster at the beginning: I will lead the system to build a safe zone

Shi Anan perked up a little: "Oh? Can you tell me about it?"

Butcher Jiang swallowed his saliva and organized his words: "We can't tell that the infected people are sick at first, but within two days they will start to have chills and fever, accompanied by coughing and even coughing up blood. Not only that, lumps, abscesses, bruises and other phenomena will appear on the skin, and in the end they will start to vomit blood and die. And after death, the corpse will turn purple and black, as if they were poisoned..."

Listening to Butcher Jiang's description, Shi An'an suddenly had an idea. Wait! Why does the description of this disease sound so much like the Black Death?

Shi Anan's heart sank little by little. Even though it was such a hot day, she felt waves of chills coming out.

The Black Death was one of the most serious plagues in human history. It once killed about one-third of the people in Europe. Its horror needs no further description.

The Black Death is actually a type of plague. The plague has various manifestations. According to the symptoms and transmission routes, it is divided into bubonic plague, pneumonic plague and septicemic plague. Among them, septicemic plague has the highest mortality rate, which is almost 100%.

Bubonic plague and septicemic plague are generally transmitted through biological contact, mostly due to flea bites on rats, while pneumonic plague is transmitted through the air.

The symptoms of the people infected in Qinghe County this time are highly similar to those described as having contracted the Black Death. The symptoms in Qinghe County may be even more serious, with a shorter incubation period, a more severe and rapid onset, and symptoms that seem to be a combination of three types of plague.

Doctor Sun noticed that Shi Anan was not in a good mood: "Miss Shi, have you thought of any solution?"

Hearing Doctor Sun's voice, Shi Anan suppressed the thoughts in her mind and forced a smile: "I may have some guesses, but if it is as I guessed, things may be a bit tricky."

"Girl, do you know what causes this? Is there a solution?" Butcher Jiang asked excitedly.

Shi Anan nodded and shook her head: "I just guessed that this disease might be a kind of plague, but I don't know how to cure it specifically."

The plague virus cannot be completely eradicated even in modern times, and even if the Black Death can be cured, its prognosis is very poor. In modern times, people mostly prevent it through vaccines and treat it with large amounts of antibiotics.

But in Qinghe County, Shi Anan doesn't have such good medical conditions. She is not a professional doctor, and she dare not give people medicine casually.

In addition, antibiotics are not cheap in the system. Even though she now has a stable way to make money, the growth rate is still too slow. She can find a way to save one or two people, but how can she save the people in a county?

Others didn't know her troubles. When Butcher Jiang heard her say it was plague, he muttered to himself: "Plague, plague, no wonder I saw rats on a corpse before."

"Miss Shi, although we don't know how to treat it yet, do you have any way to prevent it?" Doctor Sun asked again.

This time, Shi Anan did not hesitate: "I do have a way to prevent it, but it also requires the cooperation of all the people. I dare not say that it can be completely prevented, but at least the situation will be much better than it is now."

Upon hearing this, Butcher Jiang immediately said, "Miss Shi, please make the arrangements. Although I am just a butcher, I am fortunate to have the support of my brothers. I still have some say in Qinghe County. As long as we can prevent the spread of these diseases, we will fully cooperate!"

"Okay! Let's get started now. First, you need to count how many people are still in Qinghe County, which families have been infected and which are healthy, and set up an isolation area..."

Shi Anan explained some epidemic prevention measures to Butcher Jiang and Doctor Sun bit by bit.

The plague in Qinghe County is transmitted through contact, biological transmission and air transmission. Contact transmission is easy to cut off, but biological transmission and air transmission are somewhat difficult to prevent.

Therefore, it is necessary to establish isolation areas and set up multiple isolation points according to the infection area, observation area, and safe area.

After the quarantine point was built, the next step was to count and quarantine the people, because the order in Qinghe County was a bit chaotic now, with the people acting on their own or forming large and small organizations like Butcher Jiang. Originally, Shi Anan had no idea how to deal with such a situation, but fortunately she came to find Butcher Jiang first.

As one of the largest factions in Qinghe County, Juyitang showed that Butcher Jiang was quite capable. Moreover, although the people did not say anything about his behavior after the disaster in Qinghe County, they saw it all. If they had not risked their lives to deal with the infected people and corpses, their fate would have been even worse.

So Butcher Jiang told Shi Anan to make all the arrangements and leave the cooperation to him. Although there might be many people who don't obey orders, if soft tactics don't work, then hard tactics will be used. It's still easy to deal with the people.

As for some other factions who didn't care, they would try to persuade them. After all, if so many people started fighting, they would also lose some people. So Shi Anan suggested that if those people didn't listen, then they should just ignore them for the time being.

Qinghe County is so large that they could have designated a portion of the area as a quarantine point and safe zone. She hadn't thought that they could screen all the people in the county in one go.

In addition, the isolation points in the safe zone must be disinfected and sterilized. It is known that plague can be transmitted through organisms such as rats and fleas, so disinfection and hygiene become very important.

Because of the hot weather and no rain, even the water level of a lake as big as Qinghe has dropped a lot, not to mention the wells in the county. The water that was deep was fine, but the shallow water is now so shallow that you can see the bottom. In order to save water, people rarely take baths.

But this is not possible now. If we do not pay attention to hygiene, the epidemic will never be eliminated. Therefore, all the people in the safe zone and observation area must take a bath every day. As for the water, it can only be drawn from the clear lake and boiled for use.

In order to be closer to the lake, Shi Anan deliberately set the safe zone near Qing Lake, so that it would be more convenient to fetch water.

Regarding the things used for disinfection and sterilization, Doctor Sun said that he could use herbs with a little incense to have insecticidal and bactericidal effects. Shi Anan agreed with this, but this was not enough.

Early in the morning of the third day, Shi Anan and Xiao Yi arrived at the place where they had agreed to meet Yan Fei and Tie Niu. Yan Fei and Tie Niu were very happy to see her.

Yan Fei said, "Miss Shi, can we go back today?"

The two days he spent in Qinghe County were extremely uncomfortable. Not only was the smell bad, but it was also dead silent, just like a dead city. He now especially missed the hustle and bustle of their Guangming Village.

Shi Anan shook her head: "Xiao Yi and I won't go back yet, you two go back first."

Yan Fei and Tie Niu were shocked: "Why don't you go back?!"
