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

【The six most terrifying infectious diseases in history, science popularization completed】

【In addition to several horrific infectious diseases in human history, there are some diseases that we hear a lot in our lives. Some even sound scary, but they are not actually contagious.】

【For example, the following 4 diseases are not actually contagious:】

【1. Certain pneumonias】

【Not all pneumonia is contagious. Whether a lung infection is contagious mainly depends on its cause. There are two types of pneumonia that are not contagious through person-to-person contact. They are fungal pneumonia and aspiration pneumonia.. However, viral pneumonia and bacterial pneumonia are indeed contagious】

【......】

【2. Chronic bronchitis】

【Chronic bronchitis is very similar to pneumonia. Some bronchitis is contagious, but other bronchitis is not contagious. This mainly depends on the cause of bronchial airwayitis.】

【Acute bronchitis is usually caused by a viral infection and is contagious】

【However, chronic bronchitis is not contagious. It is mainly caused by exposure to environmental pollutants or long-term tobacco smoking.】

【......】

【3.Tetanus】

【Although tetanus is scary, it is not contagious. The way to get tetanus is usually when the puncture wound is contaminated by dirt or feces.】

【Pay attention to cleaning the wound promptly after injury】

【It can be rinsed with clean water that has been boiled and then cooled, or it can be cleaned with alcohol or other disinfectants.】

【Then just keep the wound site breathable】

【In addition, it can be taken with antibiotics】

【4.Malaria】

【Malaria, a potentially fatal infectious disease, is not spread from person to person】

【The disease is spread through mosquito bites】

【When a person is bitten by a mosquito, they may carry malaria parasites into the person's bloodstream, and the person may develop symptoms of malaria.】

【Malaria is still a serious epidemic worldwide】

【Approximately 40% of the world's population lives in malaria-endemic areas】

【Malaria is still the most serious disease on the Black Continent. About 500 million people live in malaria-endemic areas. About 100 million people worldwide have clinical symptoms of malaria every year, 90% of whom are in the Black Continent. The number of people who die from malaria every year is More than 2 million】

【Its clinical manifestations:】

【Incubation period:】

【The period from human infection with Plasmodium to onset of disease (oral temperature exceeds 37.8) is called the incubation period】

【Differences in the amount and strain of protozoa infected, differences in human immunity, and different methods of infection can all result in different incubation periods.】

【In temperate areas, there are so-called long incubation period strains, which can last from 8 to 14 months.】

【The incubation period of blood transfusion infection is 7 to 10 days】

【For fetal-transmitted malaria, the incubation period is even shorter.】

【For people with certain immunity or those who have taken preventive drugs, the incubation period can be extended.】

【Chill period:】

【Chill, first feeling cold at the ends of the limbs, then quickly feeling cold on the back and whole body】

【Goosebumps on the skin, cyanosis of the lips and nails, pale face, sore muscles and joints all over the body】

【Then the whole body trembles, and the teeth chatter. Some people can't stop it from covering themselves with quilts. This lasts for about 10 minutes or even an hour. The shivering stops naturally and the body temperature rises.】

【Patients during this period often feel seriously ill】

【Fever period:】

【After the cold feeling disappears, the complexion turns red, the cyanosis disappears, and the body temperature rises rapidly. Usually, the more obvious the chill, the higher the body temperature, which can reach more than 40 degrees Celsius.】

【High fever patients are in unbearable pain】

【Some are restless and moaning; some are delirium, empty, even convulsing or unconscious; some have severe headaches and stubborn vomiting】

【The patient also has red face and shortness of breath; conjunctival congestion; skin is hot and dry; pulse is rapid and rapid; urine is short and dark in color.】

【Most of them have palpitations, thirst, and desire for cold drinks.】

【Lasts 2 to 6 hours, sometimes more than 10 hours】

【After several attacks, herpes is common on the lips and nose】

【Sweating period:】

【In the late stage of high fever, the face and palms are slightly sweaty, and then it spreads all over the body, sweating profusely, and the clothes are soaked. The body temperature drops in 2 to 3 hours, often to 35.5】

【The patient feels comfortable but very sleepy and often falls asleep peacefully】

【When I wake up, I feel refreshed, my appetite is restored, and I can work as usual.】

【Now entering the intermission period】

【......】

【treatment method:】

【Since it is not an infectious disease, immunity cannot be obtained through vaccination】

【Only artemisinin can treat malaria】

【Artemisinin is extracted from the stems and leaves of the compound inflorescence plant Artemisia annua】

【When extracting, it is mainly carried out based on the principle of extraction. There are two methods that are commonly used.】

【The first is the ether extraction method】

【The second method is solvent gasoline extraction method】

【Volatile oils are extracted by steam distillation and separated by vacuum distillation; non-volatile components are extracted by organic solvents.】

【This plant is distributed in Jiujiang area】

【Although not widely cultivated, it can be found in the wild. 】(To read exciting novels, go to Feilu Novel Network!)

【After research, it was found that the use of artemisinin to fight malaria should be done through"twisting juice" instead of the traditional"decoction"."】

【Because high temperatures may destroy the efficacy of medications】

【......】

The lost eyes of the ancient people regained their energy.

They thought they would be gone if they just popularized the six infectious diseases.

There are clearly other horrific diseases that are not infectious diseases.

A typical example of this is malaria.

However, the ancients initially thought that this was also a kind of plague.

I simply didn’t expect that the mode of infection is not from person to person, but from mosquitoes to people.....

The happiest among them is the doctor.

They have been unable to effectively treat malaria.

Now, I accidentally learned the detailed treatment method on the light curtain!

"Hahaha, great, I finally understand why the patient cannot be cured with decoction!"

"Herbal remedies work! Villagers, you are saved"[]

"It turns out that instead of decoction in water, the juice in the herbs is directly squeezed out and given to patients...."

"......"

Qin Dynasty.

The people near Jiujiang carried hoes and went to dig up Artemisia annua.

Some people in their own villages need it.

Most of them are poached and sold, which can not only make some money for themselves, but also help other patients.

What makes them happiest is the treatment of malaria, which originally seemed to be a terminal disease.

You don’t even need a prescription!

Just dig out the Artemisia annua, extract the juice by yourself, and then feed it to the patient to cure the disease.

It saves trouble and money!

Xianyang Palace.

Ying Zheng recovered the infectious disease pamphlet that was being produced and added several new treatment methods for common diseases.

Done everything.

He breathed a sigh of relief,"There should be nothing wrong now."

Three Kingdoms Period.

Hua Tuo, who was imprisoned in the cell, was ecstatic

"Stop laughing! Be quiet!"

The jailer was very unhappy and knocked on the cell door, trying to warn Hua Tuo.

But Hua Tuo ignored the jailer's warning and said to himself excitedly:"This disease is called malaria, and the juice of herbal medicine must be given to the patient to be effective."

"But if the herbs are dried, will they still be effective?"

"At that time, should the herbs be ground into powder and given to patients?..."

Hua Tuo found a small branch in the cell and wrote and drew on the ground.

The jailer saw everything in his eyes and became even more unhappy. He shouted:"Hua Tuo, stop working and wait to be beheaded."

On the other side.

Cao Cao was still waiting for a cure for his headache.

It turned out that after all the popular science, I didn’t see any shadow.

His mentality just exploded!

【The fourth short video】

【Four: Epidemic prevention and control, science popularization completed,】

【Three minutes later, the fifth short video of popular science will begin.】
