Chapter 1795

"I don't know what kind of disease they have, but it's very strange and the death rate is very high." Elsa continued.

"You describe the symptoms of that disease to me, so that I can understand what it is." Liu Feng said calmly.

He suddenly had a bad premonition in his heart, wondering if he got an infectious disease this time?

Why did the other party say that so many people in the tribe are sick, and the medicine from Chang'an City is still not good.

"At first they all coughed, but after coughing for a period of time, they stopped coughing. Instead, they were sore and weak, their backs hurt, and they were covered with red rashes." Elsa felt very sad when she recalled the illness. fear.

After listening to this, Liu Ban frowned, and asked in confusion, "Cough? Weakness? Red rash?"

He has never heard of this disease, which is too strange, and he has not read many medical books recently, but he has never heard of diseases with these symptoms.

"That's right, I will die later, the situation is too serious." Elsa said quickly.

Shi Er Niang didn't dare to recall that scene, the expressions of those dead people made her so sad.

"What? Will you die after getting this disease? It's so serious!" Liu Gen didn't understand.

The whole body is sore and weak, coughing and rashes, and will eventually die. Why haven't I heard of this kind of disease?

"Yeah, at first I thought it was a common illness, but when I coughed and coughed, I suddenly stopped coughing, and it directly turned into a red rash all over my body, and I was sore and weak." Elsa said.

"Are there any other symptoms besides this? I'll be sure if I tell you more details." Liu Feng asked seriously.

Now that the current information can't give him any hints, he still sounds a little confused.

Elsa thought about it seriously, and added, "By the way, those rashes can also suppurate, and when the scabs fall off, they will form an ugly scar."

She almost forgot this most important place, many people have ugly scars on their faces.

Although some people survived the catastrophe, they were also disfigured because of the rash this time.

After Liu Feng heard Shi Er Niang's supplement, he suddenly felt that this disease was very familiar.

But he was not very sure, because one of the symptoms made him hesitate.

"What's the matter? Does Your Excellency Liu Feng know what kind of disease this is?" Elsa asked excitedly.

The lion-eared lady seemed to have seen a life-saving straw, and she was very excited.

"I think it might be smallpox, but I'm not sure." Liu Feng said seriously.

"Smallpox? What is smallpox?" Elsa continued to ask with a puzzled look on her face, "Since it's not smallpox, what kind of disease could it be?" "I didn't say it wasn't smallpox, it was just one of the symptoms you mentioned Most of them are completely consistent with smallpox, but there is one point that is a little different from smallpox." Liu Feng said.

What he wasn't sure about was the cough Shi Er Niang mentioned, as smallpox does not have the symptom of coughing.

But with the exception of the coughing symptom, all other symptoms were completely consistent with smallpox.

"Your Excellency Liu Feng, which symptom is different?" Elsa asked.

"An update, (Factory V). Please customize, please support."

Chapter 268: Inoculation.

"Cough, people who have smallpox don't have the symptom of coughing. Do they keep coughing?" Liu Feng continued to ask.

"It hasn't been all the time, it's just that I will cough in the early stage, but after coughing for a while, I don't cough anymore." Elsa said.

"Just coughing for a while and not coughing? According to what you said, there is a high probability that it is smallpox." Liu Feng said seriously. Because the symptoms mentioned later are 100% smallpox. As for the cough symptoms mentioned above, it may also be due to different times or regions. There may be a little difference.

"Your Excellency Liu Feng, what is smallpox? Can this disease be cured?" Elsa asked curiously.

At this moment, what she wants to know most is whether this disease can be cured, and whether the people in the tribe can still be saved?

"This is a very strong infectious disease, the largest virus that can cure diseases in the human body." Liu Feng explained.

Even if the patients infected with smallpox on the other side of the earth are lucky enough to be cured, they may also become blind due to corneal ulcers, and most of them will leave skin scars.

This scar is the one I mentioned for the lion's ear girl. It is a scar that falls off after the suppurative place scabs.

This scar is really ugly, and this scar is simply irreversible in this era.

The initial symptoms of smallpox virus infection include high fever, fatigue, headache and back pain, and there will be a typical smallpox rash.

These rashes were obviously distributed on the face, hands, buttocks, and legs, but there was no cough, so Liu Feng was not sure at first.

The rash begins to suppurate within a few days of the red rash, begins to scab after two weeks, and slowly develops into ringworm over the next three to four weeks. "Is it a long infectious disease? No wonder there were only a few people at the beginning, and then more and more people." Elsa suddenly realized. Now her mystery has finally been solved. At first, she thought what was going on, but it turned out to be an infectious disease.

"So try not to come into contact with these smallpox patients, otherwise you will be infected too~" Liu Feng said.

Elsa shook her head and said, "It's okay, I've been staying in the tent and haven't gone out, but I want to know if this disease can be cured?"

"The disease is mostly curable, but the mortality rate is also high."

Liu Feng said seriously.

On the other side of the world, most smallpox patients recover, and death usually occurs within one to two weeks of onset.

The mortality rate is 30%, and the smallpox virus reproduces very quickly and is transmitted through the air.

People in the Sahara prairie didn't pay attention to protection at all, and everyone didn't have masks, so the speed at which it spread was terrifying. "I already know about the high mortality rate. Many people have died in the tribe. I just want to know how to save them." Elsa sighed.

"There is indeed a way to rescue, but it is more troublesome." Liu Feng said.

Elsa's golden eyes widened immediately, and she asked, "Is there any way His Excellency Liu Feng can save them?"

Hearing that there is a rescue method, the whole person became happy, thinking that there is a solution in Chang'an City.

"That is vaccination against vaccinia. Vaccination is the most effective way." Liu Feng said.

On the ancient Chinese side of the earth, someone invented vaccination, which is to take the scabs of smallpox patients.

Then dip it in cotton and stuff it into the nostrils of a healthy person. This healthy person will be infected with some mild symptoms of smallpox, but he will never suffer from smallpox. This process is called "vaccination".

But unfortunately, vaccination has not been further developed for a long time since then.

Because the acne scab originated from humans, its application was limited. It was not until another person invented the "vaccination" that this ancient "vaccination technique" shined.

The man lived in the country, and then observed an interesting phenomenon, most of the people who deal with farm animals don't get smallpox.

And the milkmaids never had smallpox, which surprised and puzzled the man.

The man was determined to solve this mystery. After careful observation, he found that the milkmaids were not uninfected with cowpox, but the symptoms were very mild.

It's just that they have one or two blisters on their hands, and sometimes they don't even know it. The man thought, could it be that they didn't get smallpox because they had been infected with cowpox?

That person observed for many years, especially after Huaxia's vaccination was introduced to Europe, he was greatly inspired.
