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

Chapter 139

[Start the fourth short video of popular science.] 】

[4: Epidemic prevention and control. 】

[Generally, diseases that can be prevalent on a large scale are mostly infectious diseases. 】

[In fact, in human history, infectious diseases have always been around. 】

[Every outbreak of infectious diseases is a game between human beings and epidemics, and some infectious diseases have even taken millions, tens of millions, or even hundreds of millions of lives. 】

[The six most terrible infectious diseases in popular science:]

[Sixth place: AIDS.] 】

[With the spread of AIDS, it is now not an unfamiliar word to most people.] 】

AIDS is an acquired immunodeficiency syndrome caused by human immunodeficiency virus (HIV). 】

[HIV is a virus that attacks the body's immune system. 】

It takes CD4T lymphocytes, the most important in the human immune system, as the main target, destroys a large number of cells, and finally completely loses the immune function of the human body. 】

[The incubation period in the human body of HIV is 8~9 "377" years. 】

[During the incubation period of HIV, infected people can live and work without symptoms for many years.] 】

[It takes several years, or even as long as 10 years or longer, for HIV infected people to develop into AIDS patients, and then due to the extreme decline of the body's immunity, a variety of infections will occur. 】

[Such as herpes zoster, oral fungal infection, tuberculosis, enteritis, pneumonia, encephalitis caused by special pathogenic microorganisms, serious infections caused by Candida, Pneumocystis and other pathogens. 】

[Malignant tumors often occur in the later stage, and long-term attrition occurs.] 】

[Eventually, the whole body will fail and die.] 】

[And there are three ways to spread AIDS:]

[Sexual transmission, blood transmission, mother-to-child transmission. 】

[The original HIV, found in chimpanzees.] 】

[And humans can't be born from chimpanzees...]

[So there are only two ways of contagion...]

[Then the infected blacks were infected with the merchant ships transporting black slaves to the United States. 】

[However, it was not until 1981 that HIV was discovered.] 】

[To date, AIDS has killed more than 32 million people worldwide!]

[At present, there is still no effective vaccine for the pre-treatment of AIDS, and there is no drug that can eradicate it, so antiretroviral drugs can only be used to suppress the virus. 】

However, AIDS is no longer a "terminal disease" and can become a chronic disease with effective treatment. 】

And HIV prevention is simple. 】

[Remember its three modes of transmission, and stay away from the source of the virus, chimpanzees, is enough.] 】

【...】

The ancient people were frightened at first.

But when they saw that the source of the infection was a chimpanzee, they were relieved.

"Hey, it looks like an ape, why is it black?"

"Chimpanzees? I've only seen orangutans. "

"It's not ours, don't worry, I didn't look at the light curtain and said that the place where the chimpanzees stayed in the black people was the black state. "

"Oh, that's what happened, don't worry about it now. "

“..."

Qin Dynasty.

Ying Zheng looked at the ministers around him and asked worriedly:

"Zhongqing, have you ever seen this chimpanzee in the territory of Great Qin?"

"If there is, it must be eradicated, and it must not be allowed to infect the people. "

The ministers whispered to each other.

It didn't take long for them to shake their heads.

At this time, Li Si came out and replied: "Your Majesty, I have never seen it before, but the minister heard when he was studying that someone has seen a kind of wild man, burly and covered with red hair. "

"It doesn't match the picture of the chimpanzee in the light curtain, but the color doesn't match. "

"I think that chimpanzees are endemic beasts where black people live. "

Ying Zheng nodded.

The light curtain said that AIDS was not discovered until a thousand years later.

It should not appear in the Qin Dynasty.

Han dynasty.

Liu Bang pinched a cold sweat.

"According to the light curtain, once you are infected with AIDS, don't you only have a life expectancy of ten years?"

The Han Dynasty did not have the medical technology of later generations.

Once someone has this disease, they can almost wait for death.

And the death period is ten years!

Fortunately, he can be sure that he has not heard of chimpanzees in China.

In this way, AIDS, a terrible disease, would not have appeared in the Han Dynasty.

Liu Bang's heart was relieved. (If you read a violent novel, go to Feilu Novel Network!)

After a while.

He thought of one thing!

Han Shin has defected!

Liu Bang muttered worriedly: "Han Xin, where you are king, there will be no chimpanzees, right?"

He really had some hope that Han Xin would die because of it.

Another dynasty.

Liu Che exclaimed: "This disease has killed more than 30 million people!"

He was stunned.

When the Han Dynasty was first established, the population of the Han Dynasty was just over 10 million.

And to the period of his reign.

The population has only increased to more than 30 million, less than 40 million....

The number of people killed by a disease is almost equal to the number of people in his big man!

Liu Che immediately ordered a nationwide search for chimpanzees.

Once discovered, shoot directly and burn on the spot.

Tang dynasty.

"Your Majesty, there are no chimpanzees in my Datang territory. "

"Please rest assured, Your Majesty, even in the mountains and forests, I haven't seen them. "

"Chen's father had traveled all over the country, and he was sure that there was no such beast. "

“..."

Ministers spoke one after another to report their views.

"Well, in that case, let's stop this matter. Li Shimin's eyebrows stretched, and then added: "But if you find it, you must kill it on the spot, and you don't need to report it." "

"In addition, if anyone dares to hide or raise chimpanzees, they will be punished with death!"

After Li Shimin gave the order, he thought about how the first person was infected with the disease?

The ambiguous view of the light curtain is worth scrutinizing.

"Blood-borne, sexual..."

"Sexual ???"

Li Shimin was dumbfounded.

He had a bold conjecture!

People can't, at least they can't be like this, and they shouldn't be like this![]

Another dynasty.

Wu Zetian is clearly very afraid of AIDS.

This disease can be transmitted to children!

If the emperor suffers from this disease.
