I was beheaded in the Middle Ages for 20 years

Chapter 31 Droplet Transmission
"You mean the source of the Black Death was rats?"

After Feier forced herself to accept the assumption that the theory of four body fluids was wrong, what Xu Siling said later turned out to be surprisingly easy to accept.

"you can say it this way."

Xu Siling was not prepared to go into too much detail. If it was too detailed, it would require more explanation.

"The Black Death spreads very quickly. According to the two diseases you mentioned, it may not be this fast, right?" Feier thought for a while and shook her head, "For example, I shouldn't get the Black Death, but I Come on."

"Because there is another main transmission route that has not been mentioned." Xu Siling didn't think of how to explain it before. He originally wanted to say that Yersinia pestis can spread in the air, but he was afraid that Fei'er wouldn't be able to accept it for a while.

"What is it?"

"It's spread by droplets." Xu Siling could only find someone who was a little more accepting. "For example, when we talk to each other now, the Black Death is actually spreading when you talk and breathe. It's not through the corrupt body fluids or other things in the human body. What miasma spreads.”

Fei'er's blue eyes widened, and then she said: "You know that I will infect you, so how dare you come to me?"

"Isn't this asking you to wear a mask?" Although the mask was of poor quality, Xu Siling scratched his head: "There are also special methods to isolate and kill the spread of the Black Death from the outside."

"any solution?"

"Don't you smell your room?"

"Alcohol?" Mayfair's cute little nose twitched.

"Yes, it's just diluted alcohol."

Xu Siling saw the detailed planning map of Raya Town hanging on the wall in the bedroom, and immediately stepped forward to take it off. Because the map was too big to fit on the table, he could only lay it on the ground to read.

"I distilled the alcohol with brandy and then diluted it. The diluted alcohol can directly kill the Black Death when it comes into contact. If we want to build a quarantine area in the future, diluting the alcohol is essential."

Mayfair blinked innocently: "Does that mean we can cure the disease by drinking the diluted alcohol directly?"

Xu Siling, who had just taken out a pen to make plans on the drawing, couldn't help but look up at Fei'er's expression.

"What's wrong? Is what I said wrong?" Feier looked a little embarrassed.

"It's definitely normal for you to think like this, but it's not right." Xu Siling sat on the floor, thinking with her arms crossed, and then decided to explain to Fei'er.

"Actually, there are many invisible things floating in the air, including our hands." Xu Siling motioned to Feier to look at her hands, "Your hands look clean to the naked eye, but there are actually many microorganisms on them."

"The invisible microorganism means there is a microorganism in the mice that will cause us to get the Black Death, right?"

"clever."

As expected, Mayfair, who has the blessing of an atheist, is more receptive to new things than others. She will not be shackled by the so-called religion or God's words, nor will she be easily hindered by the opinions shared by everyone to hinder her thinking.

Also, if I hadn't discovered that Mayfair was an atheist, I might not have been so supportive of her.

Mayfair lowered her head in thought and frowned: "Droplet transmission. Microorganisms. Because we can't see it with the naked eye, we don't have subconscious protection, which leads to the acceleration of the spread of infection."

Xu Siling nodded: "That microorganism is called Yersinia pestis. It can survive for a period of time in the air or attached to some objects. We humans are born with no resistance to Yersinia pestis, so we will be infected immediately as soon as we come into contact with it. I just told you earlier Bet, within three days, more than half of the population in Raya Town will be infected."

Fei'er's expression suddenly became helpless and troubled: "Could it be that all the protective measures I arranged earlier are useless?"

"It is useful, but it only slows down the speed of transmission and cannot isolate it." Xu Siling began to draw on the planning map of Raya Town, "Look."

Fei'er watched Xu Siling draw busyly on the floor, sometimes crawling to the other end, sometimes crawling to the other side.

The way Xu Siling worked hard from the beginning to now was to make herself believe in him.

Previously, Xu Siling just wanted to help herself, so she gave it to Tang Fang, caring about herself and being careful.Now he is here to help the entire town of Raya.

The reason why he helped Raya Town was also because of her. From the previous chat, we can know that if it weren't for her, Fei'er, Xu Siling would not be willing to come here.

Seeing Xu Siling busy in front of him for his own sake and for saving his own Laya Town, and knowing that he had already contracted the disease and might infect him, he still came.

I didn't have time to think about it before, but now that we are talking, I have time to calm down and think about these details.

Feier suddenly felt a strange warmth in her heart. She couldn't explain what it felt like, but she felt very comfortable inside.

After a while, Xu Siling finished drawing on the drawing. Follow Xu Siling's fingers and watch him indicate to himself one by one what each circled place represents.

"In the future, one of the city gates will be closed to prevent entry and exit, and then the other open city gate will have this area set aside as an observation area."

"It is specially used for isolation and observation of outsiders or internal personnel who may be infected. They must be checked every once in a while. Once a patient with symptoms of the Black Death is found, he must be transferred immediately."

"Of course, the entire Raya Town is now in the observation stage. The main purpose of this observation area is to cope with future operations of Raya Town and prepare in advance."

Xu Siling then pointed to a very remote area next to the observation area.

"Then an area will be drawn next to the observation area, called the isolation area."

Mayfair took over the words: "It is specifically for patients who have been confirmed to be infected with the Black Death to live here and receive treatment, right?"

"clever."

I don't know why, but Fei'er felt extremely grateful for Xu Siling's praise and felt a little happy inside.

"But what should those infected with the Black Death do if they come out of isolation and come into contact with other patients after recovering from treatment?"

Xu Siling was very satisfied with Fei'er's inferences. It was comfortable to communicate with smart children.

"Now we have to talk about the soup recipe." Xu Siling had already prepared her words, "Do you think my soup recipe is useful?"

"Of course it works."

"Then do you think the soup recipe can kill Yersinia pestis just like diluted alcohol?"

Fei'er subconsciously wanted to answer yes, because she had the Black Death and was obviously much better after drinking the soup. Doesn't this mean that the soup can kill the plague bacillus?

But when Xu Siling asked such a question, he obviously told himself that the soup could not kill Yersinia pestis.

If the decoction cannot kill Yersinia pestis, how can your body get better if you drink the decoction?
Seeing the change in Fei'er's expression, Xu Siling understood that Fei'er was already thinking.

"It turns out that my soup cannot kill Yersinia pestis. I also know that you are curious about why my soup has any effect on the body if it cannot."

Xu Siling raised her index finger: "Fei'er, have you ever thought about what Yersinia pestis does to our bodies after we are infected with it?"

Fei'er was stunned. She really hadn't thought about it: "This"

Just when Xu Siling was about to explain, there was a sudden bang outside the bedroom door, followed by a shout.

"Enri, what's wrong with you!"

"Come here, Enri has fallen."
