Datang: Acting as a celestial mystery at the beginning

Sun Simiao lifted the curtain from the outside of those tents and checked all the infected people. He was not afraid of being infected, as if he had taken measures to prevent infection.

Seeing that the patient's current condition has improved, he nodded in satisfaction, sprayed another round of alcohol, passed through various disinfections, and raised his head to see Li Yi'an standing in the distance.

"Sir, the prescription you gave me is very effective."

Sun Simiao walked over and said, "The patients have drank the medicine, and their condition has stabilized a lot. Those patients with rashes and pustules have also improved and will no longer suffer from pain. Sir, you said before that you don't know how to treat medicine?"

Recently, the medicine prepared by the medical worker was found by Li Yi'an in various prescriptions in the system, which can inhibit the spread of the smallpox virus. Whether they can survive in the future depends entirely on the resistance and physical condition of those patients.

As long as you survive, you will always be immune to smallpox and will not have another attack.

Li Yi'an really didn't know it before, so he said, "This time it might be a coincidence."

Sun Simiao naturally didn't believe his statement, and said: "The epidemic prevention manual that Mr. gave to the imperial court is also very effective. All the patients are gathered together, and close contacts are brought to a specific place to observe the situation, which can effectively cut off the spread of smallpox. According to this, the smallpox crisis will soon pass, it is only a matter of time."

He has been practicing medicine for so many years, and he never thought that the plague could be dealt with like this.

Especially the method of alcohol disinfection, after a day or two of testing, the effect is obvious.

Sun Simiao added: "Your Majesty once asked me to tell me that there is another way, sir, to stop the spread of smallpox. How should I do it?"

The topic finally came to this point, Li Yian asked back: "Sun Zhenzhen has practiced medicine for many years, have you encountered smallpox cases before?"

Sun Simiao nodded affirmatively and said, "Of course there is, but after all these years, I still have no other effective way to deal with smallpox."

In ancient China, the earliest person to record the disease of smallpox and propose a treatment method should be Ge Hong of the Eastern Jin Dynasty. Later, many people used Ge Hong's method to treat smallpox patients.

Even at this time, Sun Simiao was no exception. Apart from the prescription given by Li Yi'an, there was no other feasible method.

"Did Sun Zhenren also discover a problem, if people who have been infected with smallpox can recover, they will never be infected again?" Li Yi'an asked again.

"That's true. I probably understand what your husband is thinking."

Sun Simiao nodded slightly and said, "Mr. is trying to make healthy people suffer from a relatively simple, common and easy-to-cure smallpox, so as to isolate the smallpox infection."

According to data records, medicine king Sun Simiao may be the first person to study the prevention of smallpox. It is recorded in his "Thousand Gold Prescriptions" that the acne pulp or scabs of patients with mild smallpox are exposed to normal people to achieve immunity. s consequence.

This method is also called human pox. When it was introduced to Europe in the Qing Dynasty, it was finally found that human pox was not absolutely safe. At that time, a British doctor discovered that vaccinia could also prevent smallpox. It was not until 1980 that the World Health Organization announced that human beings had defeated smallpox. .

Sun Simiao added: "A few years ago, I took a scab from a patient who had recovered from smallpox, dried it, crushed it into powder, inhaled it into the nasal cavity, and found that it was really not infected. Now I dare to go to the isolation tent to check Patients, because of this. But this method is not effective for everyone. I have tried it before, and some people will be infected by smallpox and even die. It is not safe enough, and I have no way to improve it."

Among the rewards Li Yi'an received from the system, he also had the knowledge of "Thousand Gold Prescriptions". He was not surprised by Sun Simiao's words, and said: "A real person's method is actually effective, but not completely effective, but my method can work for everyone. .”

Sun Simiao asked excitedly, "What method?"

He has also studied the prevention of smallpox for many years, but he has not come up with any results. Li Yi'an actually said that it is possible, so it is hard not to be excited.

"When General Huicheng and the others come back, Zhenren will know."

Li Yi'an pretended to be mysterious and said.

Near noon, Cheng Yaojin and his son finally appeared outside the isolation tent. They were responsible for the defense of the isolation camp area, preventing those patients from causing unrest.

Before they even got close, they were sanitized by a round of alcohol.

"Sir, we finally found it!"

Cheng Chumo led the two cows and ran back excitedly.

Beside Cheng Yaojin, there were more than a dozen cows, and he asked with a puzzled face: "Sir, do these cows really protect us from smallpox?"

"Cattle?"

Sun Simiao looked at the cows with a puzzled expression, but couldn't see anything special about them.

What does smallpox have to do with cattle?

"These are cattle recovered from the place where the smallpox broke out."

Li Yi'an squatted down, looked at the position of a cow's breech next to him, and said, "What does Sun Zhenren think this is?"

But seeing that the place was festering, even blisters and pus were formed, which was the symptom of smallpox, Sun Simiao said in surprise: "Sir, General Cheng, you back up quickly, this cow is also infected with smallpox."

"what!"

Cheng Yaojin and his son jumped up on the spot, feeling that they had been tricked by their husband, and immediately distanced themselves from the cows.

"Alcohol, bring me the alcohol!"

Cheng Yaojin shouted: "Sir, don't come close, disinfect first, otherwise it will be very troublesome to get smallpox."

Li Yi'an said with a smile: "Don't be nervous, the smallpox on cows is not harmful to people. In fact, the prevention method is the same as what Sun Zhenzhen said just now. I call this kind of cowpox!"

"Vaccinia!"

Sun Simiao pondered for a long time, then his eyes suddenly lit up: "Sir, you mean that the smallpox on the cow is more useful to people, and it won't harm the human body?"

Li Yi'an nodded and said: "If these pus cells are inoculated into humans, it is equivalent to getting a very simple smallpox. After recovery, they will be immune to the real smallpox virus."

Sun Simiao fell into deep thought, he didn't say anything, he was thinking about the feasibility.

"Since Master Sun doesn't believe it, I will be the first to inoculate you for a try, and you will know when the effect comes out."

Li Yi'an added that now that the smallpox virus is raging, vaccinia must be vaccinated.

Even if Li Yi'an has not been infected yet, as long as smallpox is still there, there is danger. Cowpox is definitely the best way to prevent it.

"No, absolutely not!"

Cheng Yaojin roared, and said eagerly: "Sir, come here quickly, those are all viruses, no! Cheng Chumo, drag me, sir, and I will tell your majesty and madam, don't let your husband do this, it's too dangerous , if you can’t hold back, I’ll break both of your legs.”

Those are the smallpox virus that will kill people, he can't let Li Yi'an take risks, and immediately rush back to Chang'an.

"Come on, show me sir, and use force if necessary!"

Cheng Chumo also panicked, and dragged Li Yi'an's hand towards Chang'an, and at the same time ordered people to drive away all the cattle.

Li Yi'an was dumbfounded by their father and son.
