Starting Today, I'll Work as a City Lord.

The whole body is sore and weak, and there will be a cough and a rash, and in the end, you will die. How come you have never heard of this kind of disease?

"Yeah, at first I thought it was an ordinary illness, but when I coughed and coughed, I suddenly stopped coughing, and it turned into a red rash all over the body, and weakness." Elsa said.

"Are there any other illnesses besides this? I'll be more specific to be sure." Liu Feng asked earnestly.

There is no way to give him any hints with the current information, and he is still a little confused.

Elsa thought about it seriously and added, "By the way, those rashes will still fester, and when the scab falls off, it will form an unsightly scar."

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

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

After hearing Shi'erniang's supplement, Liu Feng suddenly felt that this disease was very familiar and familiar.

But he wasn't sure, because one of the symptoms made him hesitate.

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

As if she saw a life-saving straw, Shi Er Niang was very excited.

"I think it may be smallpox, but I'm not very 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 the symptoms you mentioned. Most of them are completely consistent with the smallpox, but one thing is a little different from the smallpox." Liu Feng said.

What he wasn't sure about was the cough that Shi Er Niang said, and smallpox did not have the symptoms of cough.

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

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

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

-------------Chapter Dividing Line---------------

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

"Not all the time, just coughing in the early stage, but after coughing for a while, it stopped coughing." Elsa said.

"I just coughed for a while and didn't cough? According to what you said, there is a high probability that it is smallpox." Liu Feng said seriously.Because the symptoms mentioned later are [-]% smallpox, as for the cough symptoms in the front, it may also be due to different times or different regions, there is a little difference.

"Your Excellency Liu Feng, what is the disease of 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, and it is the largest virus that can be cured in the human body." Liu Feng explained.

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

This scar is the kind of lion-eared girl I mentioned, the scar that comes off after the purulent place scabs off.

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

There are also initial symptoms of smallpox virus infection including high fever, fatigue, headache and back pain, with the typical smallpox rash.

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

The rash begins to fester a few days after the rash appears, begins to crust over two weeks, and then develops into ringworm over the next three to four weeks. "A long infectious disease? No wonder there were only a few people at the beginning, but more and more people later." Elsa suddenly realized.Now her mystery has finally been solved. At first, she thought it was what happened, but it turned out to be an infectious disease.

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

Elsa shook her head and said, "That's okay, I've been in the tent and haven't gone out, but I want to know if there is a cure for this disease?"

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

Liu Feng said seriously.

On Earth, most smallpox patients recover, and death usually occurs within one to two weeks of onset.

The mortality rate was [-] percent, and the smallpox virus multiplied very quickly and spread through the air.

People in the Sahara Prairie didn't pay attention to protection at all, and everyone didn't have a mask, so the speed of the spread was terrible. "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 are indeed ways to save, but they are more troublesome," Liu Feng said.

Elsa's golden eyes immediately opened the boss and asked, "What can your Excellency Liu Feng do to save them?"

Hearing that there is a way to save, the whole person is happy, thinking that there is still a way for Chang'an City.

"That is to vaccinate cowpox. Vaccination is the most effective way." Liu Feng said.

On the other side of the earth in ancient China, someone invented vaccination, that is, taking the acne scabs of smallpox patients.

Then, dipped in cotton and stuffed into the nostrils of healthy people, this healthy person will be infected with some mild symptoms of smallpox, but will never suffer from smallpox since then. This process is called "vaccination".

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

Because the pox scab originated from people, its application was limited until another person invented "vaccination", which made this ancient "pox technique" shine.

That person lived in the countryside, and then observed an interesting phenomenon, most of the people who deal with farm livestock are free from smallpox.

And the milkmaids, who had never had smallpox, 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 one or two blisters grow on their hands, and sometimes they don't even know it. The person wondered if they didn't get smallpox because they had been infected with cowpox.

That person has been observing for many years, especially after the Chinese country's vaccination technique was introduced to Europe, he was greatly inspired.
