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

Chapter 142

【Three minutes are up】

【The six most terrifying infectious diseases in popular science】

【Start popular science No. 3: Plague】

【Plague, a naturally occurring infectious disease caused by Yersinia pestis】

【Historically, the plague was a pandemic that caused high mortality. It was called the"Black Death" in the 14th century and caused about 50 million deaths in ou.】

【Source of infection:】

【The main source of infection is rodents, including rats, marmots, etc.】

【Plague patients are mainly pneumonic plague patients, who are contagious in the early stage of the disease; septicemic plague, bubonic plague patients with ruptured adenomas, etc. can also be used as sources of infection; asymptomatic infections are not contagious】

【way for spreading:】

【1. Transmitted through flea bites】

【Most first cases of human plague are caused by flea bites】

【2. Transmitted through direct contact】

【Humans are infected through direct contact with infected animals through hunting, slaughtering, skinning, and eating meat. Enteric plague can occur by eating undercooked plague-infected animals (such as marmots, rabbits, Tibetan sheep, etc.)】

【3. Transmitted by droplets】

【The respiratory secretions of patients with pneumonic plague or animals contain a large amount of Yersinia pestis, forming bacterial particles and aerosols, causing the spread of pneumonic plague.】

【Susceptible groups:】

【Humans are generally susceptible to plague and have no natural immunity, but they can acquire lasting immunity after illness.】

【Preventive medication to reduce susceptibility】

【High season:】

【Plague epidemics in humans all occur after plague among animals. Human plague mostly occurs from June to September, and pneumonic plague is mostly prevalent after October. This is related to the activities of rats and the reproduction of rat fleas.】

【symptom:】

【The incubation period of plague is short, generally between 1 and 6 days, mostly 2 and 3 days, and in individual cases it can last up to 8 and 9 days. Among them, the incubation period of glandular and cutaneous plague is longer, about 2 to 8 days; the incubation period of primary pneumonic plague and septicemic plague is shorter, about 1 to 3 days.】

【The main manifestations of plague include acute onset of chills, high fever, sudden rise in body temperature to 39-41°C, persistent fever, severe headache, and sometimes central vomiting, shortness of breath, tachycardia, and drop in blood pressure.】

【Severe patients may develop early symptoms of decreased blood pressure, confusion, delirium, etc.】

【General treatment methods:】

【The patient should rest in bed and be given a liquid diet or intravenous infusion of glucose and normal saline to maintain water and electrolyte balance.】

【......】

【medical treatement:】

【If the fever is greater than 38.5, or the body aches are obvious, antipyretic and analgesics can be used. Those with high fever should be given physical cooling measures such as ice compresses and alcohol baths. Salicylic acid antipyretics and analgesics are contraindicated in children. Those with heart failure or shock should receive timely cardiotonic and anti-shock treatment】

【......】

【Chinese treatment:】

【There is currently no medical evidence to support the traditional Chinese medicine treatment of this disease.】

【However, some traditional Chinese medicine treatments or drugs can relieve symptoms】

【Three of the"Four Golden Gangs" of Lingnan typhoid fever, Li Piliu, Tan Xingyuan, and Yi Jusun, discussed the treatment of plague together, and after repeated discussions, they used Shengma Biejia Decoction to treat the disease."(Yi Jusun's"Collecting Medical Cases"》）】

【Tan Cizhong's"Traditional Chinese Medicine and Science" during the Republic of China stated that this method was effective in treating plague at 60-80%, and he himself cured 2 cases using this experience.】

【Li Chaodong took the method"Treatise on Typhoid and Warm Epidemics" and applied its fifteen prescriptions to treat plague, and the effect was ideal:"This year in Guangdong, the plague is prevalent, and I treat it according to the law, and everything is different.""】

【Preventive measures:】

【Kill rats and fleas, monitor rat plague, and strengthen epidemic reporting】

【Cars, boats and other means of transportation coming from epidemic areas should be strictly quarantined, and suspicious persons should be quarantined】

【People in and around epidemic areas and staff participating in epidemic prevention should be vaccinated against plague】

【"Three Musts" and"Three Don'ts" for Plague Prevention"】

【"Three essentials"】

【Report any sick (dead) marmots and other sick (dead) animals;】

【If you find a plague patient or a suspected plague patient, you should report it immediately;】

【If a patient is found to have died of sudden death for unknown reasons, he should report it immediately】

【"Three no"】

【Do not touch, skin, or cook sick (dead) marmots and other sick (dead) animals;】

【Do not sit or rest around marmot holes to prevent flea bites;】

【Not visiting the homes of plague patients or suspected plague patients, visiting and caring for them, or paying homage to the deceased at their homes.】

【......】

The ancients gasped after reading this.

Who would have thought that rats and fleas lurking around us can also bring fatal diseases!! ?

"No way? Can tiny mice make people sick?"

"I don't believe it, I want to catch a mouse to eat"

"It's over. I have fleas on my body and I haven't bathed in months...."

"Worri! Stay away from labor and management! Beware of plague"

"......"

People spontaneously stayed away from others, especially those who were dirty.

And people who are really smart have already thought of raising cats to prevent rats.

The light curtain did not say that cats can also be infected with plague. Since it is okay, letting cats eat mice can prevent the source of the virus.

Qin Dynasty.

Ying Zheng couldn't believe it.

Inconspicuous mice and fleas can also carry deadly viruses.

And the most terrifying thing is that the light curtain did not tell Chinese medicine how to treat the plague!

Once someone gets sick, doctors in the Qin Dynasty really have no good solution

【Limited time Q&A session】

【Please answer the following questions correctly within 30 seconds to get generous rewards】

【What is the main source of infection of plague?】

【Option 1: Sheep, buffalo and other livestock】

【Option 2: Chicken】

【Option 3: Rodents, including rats, marmots, etc.】

【Option 4: Primates, including monkeys and orangutans. ]

Ying Zheng’s eyes lit up.

It seems like there hasn’t been a Q&A in a while. (To read Baoshuang novels, go to Feilu Novel Network!)

He almost forgot about it.

Without hesitation, he immediately replied loudly:"Option three."

30 seconds passed in a blink of an eye.

【correct answer】

【Congratulations to Ying Zheng of Qin Dynasty, Liu Bang, Liu Che and Liu Xiu of Han Dynasty...More than 100 emperors including Cao Cao, Liu Bei and Sun Quan of the Three Kingdoms, Li Shimin and Wu Zetian of the Tang Dynasty, and Zhu Yuanzhang and Zhu Di of the Ming Dynasty answered correctly.】

【Everyone receives the following rewards:】

【《A copy of"Ji Si Medical Cases", a copy of"Traditional Chinese Medicine and Science", a copy of"Treatise on Typhoid and Warm Epidemics", and 30 credits. 】

The next second.

Ying Zheng had three more medical books in his hand.

He couldn't help but be overjoyed,"God helps me!"

Han Dynasty.

Liu Xiu looked excited.

He shouted excitedly:".I am worthy of being a son of the plane!"

"First, there were immortals to help, and now there are people from later generations to help, and there is this magical light curtain."[]

The surrounding ministers looked at their Majesty with enthusiasm.

Only when you see it with your own eyes can you know how unlucky your Majesty's fortune is!

Ming Dynasty.

Zhu Yuanzhang is holding three medical books and feels happy

"Come, please make a few more copies."

Then, he frowned and thought about how to prevent the plague.

After thinking for a while, he really had no idea.

Even if he was the emperor of the Ming Dynasty, he couldn't control rats and fleas. He couldn't give them orders to prevent them from breeding. Just exterminate the species?

Zhu Yuanzhang turned to look at the minister,"Tell us, where are there more rats?"

"Return to Your Majesty, there are the most rats in the granary"

"Yes, there is also the treasury, and there are many rats in it, and they are all very fat."

Zhu Yuanzhang immediately thought of a way

"We all know it, and we have ordered that cats be raised in granaries across the country. Remember, feed them less and let the cats catch the old (okay, okay) rats."

Qing Dynasty.

Kangxi and Qianlong fell into deep thought.

Uh....

As we all know, people in the Qing Dynasty had to wear braids.

Forget it, rich people wash their hair at least twice a week and have almost no fleas on their bodies.

But ordinary people are completely different.

That rascal.

Because the hair is too long, it needs to be rolled up, which is very inconvenient.

In order to save trouble, common people rarely take off their braids and wash their hair.

As you can imagine, the taste......

And to what extent the hair has become covered with dirt.

And this, of course, is indispensable for the visit of fleas.
