The days when I fished in Daming

Chapter 18 Breeding Cowpox
On this day, Zheng Xiong saw the smallpox vaccination method sent by Fengyang Mansion, and the memories of his previous life emerged one by one.

In ancient times, smallpox was also somewhat effective in vaccination against human pox, and it was basically self-isolated and rigid.

The features are also obvious.

The incubation period is generally 8 to 12 days, and the onset occurs suddenly, with systemic symptoms such as high fever, headache, and vomiting.On the first 1 to 2 days of the onset, a transient measles-like or scarlet fever-like rash (herdrash) may appear on the lower extremities, inner thighs, underarms, and both sides of the waist.

On the 3rd to 4th day of the onset, the body temperature drops rapidly, the subjective symptoms are alleviated, and a centrifugally distributed rash appears at the same time, that is, the head, face, and extremities are denser than the trunk.

It starts as a dark red macule, which turns into papules after a few hours, and turns into blisters on the 6th to 7th day of the disease period.The center is depressed, and there is a blush around it. At this time, there are also rashes in the mouth, throat, corners of the eyes, and conjunctiva.

On the 8th to 9th day of the disease period, the blisters turned into pustules. At this time, the body temperature rose again, and the symptoms of poisoning became more serious. On the 11th to 12th day of the disease period, the pustules gradually dried up and formed thick yellow-green scabs. The body felt itchy and the body temperature gradually dropped.

There was also an outbreak in the Ming Dynasty, but it was nothing compared to the outbreak of the plague in the last years of Chongzhen.

At that time, no grass grew wherever the plague went. It is a bit one-sided to say that the last years of Chongzhen was the Little Ice Age, and natural and man-made disasters occurred frequently, which led to the subjugation of the country.

The main reason is that the plague also broke out in Shuntian Mansion. Ten rooms were empty, and at least one-third of the population in Shuntian Mansion died.Li Zicheng was able to take down Shuntian Mansion smoothly. Later, Li Zicheng pulled so hard, and the army was also infected by the plague.

Looking at his adopted sons, he knew that Li Zicheng's army did not lack combat effectiveness.

Smallpox was the most rampant in the Qing Dynasty, and the entire royal family died of smallpox.Why is Kangxi also called Kang Mazi? Even though he had smallpox when he was a child, he survived by luck, and he also got pockmarks all over his face.And people who get smallpox and survive will not get it again in the future, and can live for a long time.

Kangxi's superior position also has smallpox credit.

It was smallpox that was plundering, so the Qing Dynasty paid more attention to smallpox, and the smallpox vaccination method was also vigorously promoted, but the risk was still very high.Smallpox has only been weakened, and the body's own immune system does not mean that it can defeat it.

It was not until the appearance of cowpox that smallpox was truly eradicated. Other animals who had smallpox were still smallpox, and people could still be infected if they came into contact with it.When a cow gets smallpox, it is not like other animals. It is equivalent to directly changing its species, which is not harmful to the human body, but it is equivalent to getting smallpox once and being directly immune.

Cowpox is not so easy to use as it is, it needs to be cultivated, and it can be used directly after infection, which is definitely not possible.It takes about five days for the cattle to adapt to smallpox and allow the smallpox to mutate.

The vaccinia of one cow can be inoculated to many people. It is really inconvenient to preserve it in this era. It can only be cultivated one by one, slowly cultivated, and slowly vaccinated.

Just do it when you think about it, the errand work, Wang Er and Zhao San are not free, so they recruited two more errands, and they have the right to not use it, and it will be invalid after the expiration date.

It feels good to make other people feel good, but it would be nice not to be led by others in the previous life.

The names of the two newcomers are also simple, Qian Wu and Saturday.

Two people were called, and the task was given.

"You two go find some cows and find a sparsely populated open space near here"

"It's better to have a yard that can be isolated, and then ask where someone has smallpox, and tell them to infect the cow."

"All the money is prepared for you, don't be afraid to spend money, you will also be rewarded, and it is no problem to leave your name in history if you do it well, this is very important, for the sake of the common people, don't make trouble for me."

Originally, the two were reluctant, this thing would kill people if they were not careful, but it is a bit tempting to leave a name in history.Certainly not because of money, but for the sake of the common people in the world, it is incumbent on them.

"By the way, after you find someone, don't touch them directly. Get him a carriage and let him drive there by himself. Bring more alcohol and spray it at any time. Go get some quicklime. Sprinkle it on everything you pass."

The two of them did not dare to neglect the order.

Qian Wu went to look for the yard. There are still uninhabited houses in the suburbs. You don’t have to worry about money. The matter is very simple. The owner of this poor place is eager for someone to buy it, and Zheng Xiong is too lazy to rent it. No matter what age the land and houses are valuable.

The cow is more troublesome. Lao Zhu is very strict about this and prohibits private sales.

Find the household department, sign a contract with the owner of the cow, and explain the purpose.Huimin Pharmaceutical Bureau uses cattle for experiments. I don't understand the meaning, and I don't dare to stop them. Who hasn't had a serious pain or ailment yet.

It's easy to inquire about people who have smallpox on Saturdays, and everyone avoids them, just ask a little.This thing also has an incubation period, it will appear from time to time, and it is hard to guard against.

I found a little boy named Zhang who was waiting to die, but his father didn't want him to go out, so he might have died outside.

"consistent"

"It's not about money"

"Twice"

"I'm away from home, what if there is an accident?"

"Five passes, no more, if not, I'll go find someone else."

"make a deal"

The child's father could only agree with tears in his eyes. It was his fate. When Huimin Pharmacy took over, he would definitely try his best to protect his child.

Money is of course also an important factor.

Heaven feeds man with all things, and man has nothing to repay heaven.

Raising children to guard against old age is not all about family affection, there must be a little bit of this in mind.

But the family relationship that we get along day and night is not something that can be broken away with just a few words.

On Saturday, according to Zheng Xiong's request, alcohol was sprayed over and over again, and lime was also sprinkled along the way.He also left some disinfectant for the child's father, whether he listened to it or not is another matter, as long as he has had smallpox, he won't get it again.

Pockmarks are not all on the face.
