On this day, Zheng Xiong saw the human pox inoculation method sent by Fengyang Mansion, and the memories of his previous life surfaced one by one.

In ancient times, smallpox also had some effects on human pox inoculation, which was basically consciously isolated and stiff.

The characteristics are also obvious.

The incubation period is generally 8~12 days, with sudden onset, with systemic symptoms such as high fever, headache, and vomiting. On the 1st ~ 2nd day of onset, a transient morbilliform or scarlet fever-like rash (prodromal rash) may appear on the lower limbs, inner thighs, armpits, and both sides of the waist.

On the 3rd ~ 4th day of onset, the body temperature drops rapidly, the self-perceived symptoms are reduced, and a centrifugal rash appears, that is, the head, face, and extremities are denser than the trunk.

At first, it is a dark red macule, which turns into a papule after a few hours, and becomes a blister on the 6th ~ 7th day of the disease period. The center is depressed, and there is a redness around it, and there is also a rash in the mouth, throat, corners of the eyes, and conjunctiva.

On the 8th ~ 9th day of the disease period, the blisters turn into pustules, at this time the body temperature rises again, the poisoning symptoms are aggravated, on the 11th ~ 12th day of the disease period, the pustules gradually dry out, form a yellow-green thick scab, feel sharply itchy, the body temperature gradually drops, the general condition improves, and after 2~4 weeks of the disease period, the scabs begin to fall off, leaving scars.

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, the plague did not grow anywhere, and it was a bit one-sided to say that the last years of Chongzhen were the Xiaoice River period, and natural disasters and man-made disasters were frequent, which led to the death of the country.

A large part of the reason is that the plague also broke out in Suncheonfu, ten rooms and nine empty, and at least one-third of the population of the entire Suncheonfu died. Li Zicheng was able to successfully conquer Shuntianfu, and later Li Zicheng pulled it, and the army was also infected by the plague.

Looking at his righteous sons, you can see that Li Zicheng's army does not lack combat effectiveness.

Smallpox was the most rampant in the Qing Dynasty, and the entire royal family died of smallpox. Why is Kangxi called Kang Mazi again, that is, he had smallpox when he was a child, and he luckily didn't die, and he also got pockmarks all over his face. And those who do not die of smallpox will not have it again in the future, and they can live for a long time.

Kangxi's ascendancy also has the credit of smallpox.

It was smallpox that was rampant, so the Qing Dynasty also paid more attention to smallpox, and the human pox inoculation method was also vigorously promoted, but the risk was still very large. Smallpox has only been weakened, and the body's own immune system is not saying that it can defeat it.

It wasn't until the advent of cowpox that smallpox was truly eradicated, and other animals still had smallpox, and human contact would still be contagious. Cattle with smallpox are not like other animals, which is equivalent to directly changing it, which is not harmful to the human body, but it is equivalent to getting smallpox once and is directly immunized.

Cowpox is not so simple to use immediately, but also to cultivate, just infected directly to use, definitely not good. It is necessary to let the cattle adapt to smallpox and let the smallpox variety, which is usually about five days.

A cow's vaccinia can inoculate many people, and it is really not convenient to preserve it in this era, so it can only be cultivated one by one, slowly cultivated, and slowly inoculated.

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

It feels good to support others, and it would be good not to be supported by others in your previous life.

The two names of the newcomers are also simple, money five, Saturday is it.

Two people were called and the task was ordered.

"You two go find some cows and find a sparsely populated clearing around here."

"It's better to have a yard to isolate them, and then ask where anyone has smallpox, and tell them to infect the cow."

"The money is ready for you, don't be afraid to spend money, you are also indispensable for rewards, do a good job and let your name go down in history, this matter is very important, for the sake of the world, don't give me a basket."

Originally, the two were reluctant, this thing would die if they were not careful, but it was a bit tempting to leave a name in history. It's definitely not because of money, it's incumbent on the people of the world to live.

"By the way, after finding someone, don't make direct contact, get a carriage for him, let him rush over by himself, bring more alcohol, spray it at any time, go get some quicklime, and sprinkle it on me everywhere I pass."

The two of them got the order, and they didn't dare to slack off.

Qian Wu went to find a yard, there are still houses in this suburb where no one lives, don't worry about money, things are very simple, the owner of this broken place wishes someone would buy it, Zheng Xiong is too lazy to rent, no matter what era the land and houses are valuable.

Cattle are a little more troublesome, Lao Zhu is very strict with this, prohibiting private trading.

Go to the household department, sign a contract with the owner of the cow, and explain the purpose. Huimin Pharmacy experiments with cows, I don't understand the meaning, and I don't dare to stop it, who hasn't had a big pain or a small illness.

On Saturday, I went to inquire about people who had smallpox, and it was easy to inquire, and everyone avoided them, and they could ask a little. This thing also has an incubation period, which appears from time to time, and it is impossible to prevent it.

found a little boy surnamed Zhang, who was waiting to die, and his father didn't want to let him go out, so he might die outside.

"Consistently"

"It's not about money or money"

"Two runs"

"What if there is an accident?"

"Wuguan, I can't do it any more, if it doesn't work, I'll go find someone else."

"Deal"

The child's father could only tearfully agree, it was originally a fate, Huimin Pharmacy came to take over, and he would definitely try his best to protect his child, and the little people were not unable to see the situation.

Money is of course also an important factor.

Heaven feeds people with all things, and people have nothing to repay the sky.

Raising children to prevent old age is not all family affection, and they must all have this in mind.

But the family affection that gets along day and night is not something that can be parted with one or two sentences.

On Saturday, according to Zheng Xiong's request, he sprayed alcohol over and over again, and lime was also sprinkled all the way. also left some disinfection for the child's father, whether to listen to it or not is another matter, as long as you have smallpox, you will not get it again.

The pockmarks are not all on the face, either.
