In addition to the above methods, there is also ethylene oxide gas closed disinfection method.

Ethylene oxide gas closed disinfection method is to put ethylene oxide gas in a closed container to achieve the purpose of disinfection and sterilization at a standard concentration, humidity and time.

Ethylene oxide is a broad-spectrum gas fungicide, which can kill bacterial propagules and spores; as well as fungi and viruses, among others.

Ethylene oxide has strong penetrating power, no damage to most items, and can be quickly volatilized after disinfection, especially suitable for items that are not resistant to high heat and lukewarm.

Such as precision instruments, electronic instruments, optical instruments, heart-lung machines, pacemakers, books and documents, etc., there are no side effects such as damage and corrosion.

The old vinegar fumigation method proposed by Liang 18 is still in use in later generations, and the effect is still very good.

Liu Mintian pondered for a while, and said with an idea: "Grandpa Liang, the little girl still wants to ask you a question!" ”

Liang 18 heard Liu Min say that he wanted to ask him a question, and laughed a few times and said: "Gongzijian and Zhang Jing both called Miss Min Fairy Sister, and your guidance and conversation in the palace hall just now made the old man admire him so much, what else do you want to ask the old man!" ”

Liu Min sneered and said: "Three stinkers can top one Zhuge Liang, Grandpa Liang is a horse trainer at Qingshichuan Horse Farm, and he knows so much about disinfection and sterilization; Toshiko asks you for advice and learns, that's how it should be! ”

Liang 18 was a little fluttering by Liu Min's tall tree, and said with a laugh: "Miss Minzi, you don't want the tall tree to be old!" If there is anything to ask, as long as you know, you will definitely tell you word for word! ”

Liu Min was stunned and stared at Liang Shibadao: "Minzi wants to ask if there was any virus infection when rescuing the wounded during the war!" ”

"Yes! The best way to dispose of the corpse after a battle is to dig a pit and bury it or cremate it; Rescuers can become infected if they are not strictly protected! Liang 18 said impassionedly, raised his arm and said: "When the soldiers of the Qin army conquered the Central Plains, they had to take off the heads of the enemy, and many of them contracted the epidemic and had to be isolated; If the corpses are not buried in time, a plague that is difficult to resist will occur. ”

Liang 18 said, sighing: "War is often the flashpoint of disease; In general, in skirmishes, the opposing sides dispose of the remains of their own soldiers, and many of the bones left at the scene of the battle are used as evidence for the soldiers to receive rewards, and the corpses are allowed to decompose or be taken away by wild beasts; Some even hung the corpses, and the victors only blocked the affected areas to deter the enemy, and no one managed the burial of the corpses at all! In extremely tragic large-scale battles, it is common to dig mass graves to bury corpses, burn them or throw them into rivers! ”

Liu Min gasped and said bitterly: "Such cruel wars occur frequently, no wonder plague and cholera harm mankind!" ”

Liang 18 heard Liu Min mention the plague and cholera, staring at her in a daze, not knowing what to say.

At this moment, he saw three or four soldiers coming from a distance, and Liang Shibai immediately opened his voice and shouted: "Chen Yiyu, Tu Youmei, Lai Zhenyue, you three come here, come here, come quickly!" ”

The three soldiers who were replaced by Liang 18 as Chen Yiyu, Tu Youmei, and Lai Zhenyue ran over, but they were three young men who were born in Maosheng.

Chen Yiyu, who was running in front, came to Liang 18 and shouted, "What does the master command!" ”

After Chen Yiyun said this, he looked around, and saw Liu Min, Hongyun, Lu Xing, Lan Mei, and Bai Xue five beauties standing aside, and their eyes showed excitement.

Tu Youmei and Lai Zhenyue then arrived and did not ask Liang 18 what was going on; first stared at Liu Min's five beauties with surprised eyes.

Liang 18 saw that Chen Yiyu, Tu Youmei, and Lai Zhenyue were all focused on staring at the beauty, and stepped forward angrily, and no one on the foreheads of the three of them chiseled a chestnut and laughed angrily: "Have you seen enough, there will be time for you three rabbit cubs to watch next!" ”

When Chen Yiyu, Tu Youmei, and Lai Zhenyue heard this, they hurriedly knelt on the ground and kowtowed: "Master, what do you want the apprentice to do, the apprentice is not afraid to go up the sword mountain and down the sea of fire!" ”

"Let your mother's big ass fart!" Liang 18 scolded suddenly, and from this scolding, it can be seen that Liang 18 has prestige in the minds of Chen Yiyu, Tu Youmei, and Lai Zhenyue.

After Liang 18 finished scolding, he said solemnly: "The three of you immediately go back to the warehouse to get a big iron pot and a bucket of old vinegar; Carry a bag of quicklime to the cell, and the master and Miss Min, Hongyun, Green Apricot, Blue Plum, and Bai Xue will go there immediately! ”

Chen Yiyu, Tu Youmei, and Lai Zhenyue heard Liang 18 say this, bowed and stood up in response; Lai Zhenyue said with a mouthful: "Does the master want our third brother to work with these sisters!" ”

"you son of a, just thinking about this kind of thing!" Liang 18 kicked Lai Zhenyue's ditch egg, and Chen Yiyu, Tu Youmei, and Lai Zhenyue ran into the distance with a smile.

Liu Min smiled and said, "These three boys must be Grandpa Liang's apprentices?" ”

"That's right, these three monkey sons are learning to train horses from the old man!" Liang Eighteen chattered endlessly: "Of course, I also disinfect with the old Xue and clean the hygiene of the stable!" ”

After Liang 18 finished saying this, he glanced at Liu Min and said, "Miss Min just said that what happened to the plague and cholera?" ”

Liu Min was stunned, and simply told the information he had read in later generations about the plague.

At the end of the Eastern Han Dynasty, the population of the country dropped sharply from more than 20 million to more than 3 million; War deaths are one aspect, but many more are dying from the plague that followed the war; The plague was the plague or cholera.

Since the middle of the Eastern Han Dynasty, epidemics have appeared, and they are becoming more frequent and more intense; At the end of the Eastern Han Dynasty, the epidemic peaked at its peak.

In the last 30 years of the Eastern Han Dynasty, there were 12 national plagues; There are countless small-scale endemic outbreaks.

The most terrible years were 204-219 A.D., when the plague ravaged the population, with mortality rates of 50% or more in many places.

Zhang Zhongjing, a medical saint, described in "Treatise on Typhoid Fever and Death" that "the Yu clan is a lot of people, more than 200, since the establishment of An'an, it has not been ten years, two-thirds of its deaths, and typhoid fever is seven out of ten."

From the end of the Eastern Han Dynasty to the beginning of the Three Kingdoms, it was the most dramatic period of population decline in China's more than 3,000 years of recorded history.

The population plummeted from more than 60 million to less than 15 million, and the plague may be the number one killer in this era of suffering; The role in reducing the population is much greater than that of war and famine.

The Great Plague of the late Eastern Han Dynasty was a virus transmitted by mammals as a reservoir and was characterized by sudden high fever and severe respiratory symptoms. and the development of infectious diseases with blood spots and bruises.

Combined with the characteristics of the symptoms and their high lethality, it is inferred that plague is the most likely.

Liang 18 listened to Liu Min's account of the epidemic epidemic in the late Eastern Han Dynasty, and sighed: "The old ancestors also talked about infectious diseases in ancient times, and the incubation period of this disease in the human body is about ten days!" ”。

Liu Min said: "Grandpa Liang is talking about typhoid fever, and the human body is the only host of typhoid fever; However, typhoid bacilli can survive for a long time even after leaving the body. ”

Liang 18 said: "The onset of this disease is relatively slow, so in the early stage of the disease, the main symptom of the patient is fever, accompanied by general malaise, dry throat and other conditions. And as the condition gradually becomes severe, the patient's body temperature will gradually rise, and most patients will still have chills symptoms during the initial attack, and the amount of sweating will be relatively small when the fever is reduced......"
