I make a popular science video and all the emperors learn from it!

【The six most terrifying infectious diseases in popular science】

【The first place to start popular science: smallpox】

【Smallpox virus killed nearly 500 million people!】

【thus becoming the most terrifying infectious disease】

【Smallpox is an ancient infectious disease. It is highly contagious, severe, and has a high mortality rate. After treatment, dense pockmarks will appear on the face of the recovered person, hence the name.】

【Emperor Kangxi of the Qing Dynasty was infected with this disease, and thus got Kang Mazi's attention.】

【Smallpox virus has been popularized before】

【Not much introduction here】

【Only treatment methods and prevention methods are introduced】

【treatment method:】

【To date, there is no established effective treatment for smallpox】

【Patients infected with smallpox must be strictly isolated until they recover, and the isolation period must not be less than - 40 days after the onset of illness】

【Their clothes, utensils, respiratory secretions, and herpes exudates need to be strictly disinfected, and those in contact with the patient should be vaccinated immediately】

【Patients are usually treated with supportive care, giving them adequate fluids and nutrition, such as intravenous electrolytes, nutritional supplements, or medications to control high fever or pain. At the same time, young and frail patients are given antibiotics to prevent bacterial infections following smallpox virus infection. , strengthen care and keep eyes, mouth, nose and skin clean. Symptomatic treatment of corneal ulcers, rashes, etc.】

【prevention:】

【Because there is no treatment, prevention is the only option】

【Prevention is by vaccination against smallpox (vaccination)】

【Popular science on how to get vaccinated】

【There are two methods, one is the variola method, and the other is the safer cowpox method.】

【Pox method:】

【In the 16th and 17th centuries, variolation was widely used throughout China and spread to other surrounding countries, and was highly praised by all countries.】

【The specific method is to use the pox pus or acne scab powder of smallpox patients as inoculation materials, and try to send it into the nasal cavity of non-patients to cause localized acne rash, thereby obtaining immunity to smallpox.】

【......】

【Cowpox method:】

【However, the traditional method of variolation is not safe, leaving large scars in some cases and risking death in severe cases.】

【In 1738, after the use of variola scabs as vaccination material, the mortality rate dropped significantly, but 0.2 to 0.5 people still suffered misfortunes.】

【Jenner, a French doctor, accidentally noticed that milkmaids and stable grooms were often safe during smallpox epidemics and rarely became infected.】

【"What causes this?"】

【After further investigation, Jenner discovered that cows can be infected with smallpox just like humans. The red, swollen abscesses on the cows' udders are very similar to the symptoms of smallpox patients.】

【Milkmaids often get cowpox initially, but the strange thing is that no matter who gets cowpox, they never get smallpox again.】

【Similarly, horse breeders and coachmen often suffered from a form of herpes similar to"equine heelitis" but later acquired immunity to smallpox.】

【During variola vaccination, Jenner also found that people who had been infected with bovine smallpox or suffered from human smallpox often did not react to variola, and even if they did, they were very mild.】

【......】

【After more than ten years of repeated observation and testing,】

【On May 14, 1796, Jenner prepared for the final step—human experiments.】

【With excitement and anticipation, he squeezed out a bit of the 14-year-old cowpox serous fluid on the arm of the milking girl Nelms, and"planted" it on the arm of an 8-year-old healthy boy, where he used a needle to scratch it. There are two shallow marks about 2 cm long.】

【From the 4th day onwards, a series of typical initial reactions such as papules, blisters, pustules, scabs and scabs appeared on the shallow marks.】

【After half a month, the boy only felt mild discomfort all over his body.】

【In order to verify the effect, he was vaccinated with variola on July 19, but no smallpox symptoms appeared.】

【This is the first successful trial of human cowpox vaccination in human history】

【Later, they switched to abscess slurry from infected cows, and finally switched to vaccinia vaccine recipients. After dozens of tests, the same immune effect was achieved.】

【......】

The ancient people were moved to tears.

Previously, the light curtain only gave the emperor the vaccine to prevent smallpox, and they could not ask the emperor for the vaccine, but they were greedy for it. it's good now.

There are two vaccination methods to choose from.

Even the detailed vaccination process and results were not reserved at all.

They just do it

"I won’t say any more. I’ll give the light curtain a few kisses first."

"Great, my parents are saved"

"Who has had smallpox? Can you give me some scabs?"

"Brother, if you are not in a hurry, just use the cowpox method. You can ensure that you are not the unlucky one among the 20 to 50 people?"

"Yes, let's wait and find the cows infected with smallpox."

"......"

Qin Dynasty.

The doctors were completely dumbfounded.

"Is there such a cure?"

"It's prevention! It's not a cure, but after vaccination, you won't get smallpox again for the rest of your life. It's really miraculous."

"..."

The head of the medical family talked with several doctors about his thoughts.

In later generations of medicine, it is really difficult to integrate the theories of traditional Chinese medicine.

Xianyang Palace

"The widow has become."

Ying Zheng finally completed the pamphlet for treating infectious diseases.

Han Dynasty.

Liu Bang pondered for a moment and asked the officials:

"Everyone, has anyone been found infected with smallpox in Han Dynasty?"

The horror of smallpox is deeply rooted in the hearts of the people.

Liu Bang thought that if someone had contracted this disease, he would take the opportunity to vaccinate the people across the country.

The ministers shook their heads in response.

Liu Bang nodded,"It's okay if you don't have it. Pay close attention. Once someone gets sick, immediately Report to the court."

Another dynasty.

Emperor Wu of the Han Dynasty Liu Che's eyes were full of novelty. (To read Baoshuang novels, go to Feilu Novel Network!)

He had been vaccinated against smallpox before.

This would not worry about infection at all.

But he did not expect that smallpox This is how vaccines are made

"What was going through the head of the first person to be vaccinated?"Liu Che was shocked that he could think of such strange prevention and control methods.

Tang Dynasty.

Li Shimin withdrew his gaze and immediately issued an order

"Come and search for cows infected with smallpox across the country. The finder will be rewarded with a hundred gold! Those who take the initiative to turn it in will be rewarded with gold!"

"yes! His Majesty."

Money and silk touch people's hearts, and Li Shimin got the essence of it.

If he had ordered people to look for it himself, it would be time-consuming and laborious, and he might not be able to find it. But it is different to reward silver.

There will be a steady stream of people taking the initiative to do it, and it is very Work hard.

Ming Dynasty.

Zhu Yuanzhang didn’t want to spend money at all.

He thought of a great idea

"According to our oral instructions, if a person is found infected with smallpox in the Ming Dynasty, he will be locked up in a cowshed."

"When will the disease be cured and the person released?"

"If the cow is infected with smallpox, that's great. It must be turned over to the government, and the government will buy the cow."

Zhu Yuanzhang looked proud.

The Ming Dynasty had just founded the country and was very poor?

It was okay.

He had many ideas and could get things done even if he had no money!

Soon, the decree was issued to all parts of the country.

When the people saw this"outrageous" imperial decree, they were stunned.

What do you mean?

The holy will is really unpredictable! []

Qing Dynasty.

People were happily trying to infect cattle with smallpox.

In this way, a safer cowpox method could be used.

There was no need to take risks anymore.

At this time, Kangxi in the palace was unhappy.

He looked at the reports from various places.

He couldn't help but got angry:"Damn light curtain! Humiliate me again! And the stupid people everywhere! He actually refused the variolation method"

"You even dare to disobey my will!"

It was difficult to find cattle infected with smallpox, so he directly ordered an improved version of variolation.

But the people of the Qing Dynasty stayed behind closed doors and were unwilling to use variolation!

This was the same as violating the imperial edict.

What made him even more angry was that , even after someone was vaccinated, he did not thank him as the emperor, but thanked the hateful light screen, and kowtowed to it.

This made Kangxi so angry that he could explode!

He wished that all the stupid people would be dragged to the execution ground and beheaded!

Another dynasty.

Qianlong was even more angry.

Because he was exposed once, his reputation was a bit bad.

The common people directly vaccinated themselves without asking the court for help.

Qianlong looked very unhappy,"If you vaccinate yourself, won't my achievements be lost?""

"Get them to stop self-inoculation immediately!"

"When I find the infected cows, I will vaccinate them!

A sober minister immediately remonstrated:"Your Majesty, there are many places suffering from this disease now. I'm afraid they can't afford to wait.""

Qianlong directly glared at the minister.

"Shut up! How could I not know that you don’t see how dangerous the variolation method is? Wait until I find the infected cows before vaccinating them."

"Tell them to wait a little longer."

The minister wanted to continue to dissuade Qianlong.

He was immediately pulled down and beaten.............two..
