After entering, Aoeda saw that there were two marching beds and two low stools in the tent, and guessed that this was the room where he and another imperial doctor were staying.

Standing in the tent, the permanent imperial physician said, "The place is small, so I won't invite Dr. Kong to sit." ”

Qingzhi said politely: "It's okay. ”

Imperial Doctor Chang got straight to the point and said: "What you said about Weixi, but there is really such a thing?" ”

Qingzhi said: "Naturally, there is. ”

Doctor Chang said: "Then you mean, you are optimistic about those students because they ate wild vegetables and spinach with flavor, not because they ate citrus?" ”

"Spinach and citrus are both rich foods with flavor, and eating either can cure those students."

"I don't understand, why do you think it's because the food with flavor has cured them? In my early years, I traveled north and south, but I had never seen this disease in the citrus countryside of Jeju, and everywhere else. ”

Qingzhi said: "Chang Imperial Doctor, there should be another place where you have never seen this disease. ”

"Where?"

"The Imperial Palace."

There was never a stop of fresh fruits and vegetables in the palace, and it was impossible for anyone to suffer from this disease.

After pondering for a moment, Imperial Physician Chang said, "It is true that no one in the palace has ever suffered from this disease, but that is also because there is no shortage of citrus in the palace, right?" ”

"And what about summer days without citrus? Imperial Doctor, have you ever seen someone in the palace suffering from this disease in the summer? ”

Imperial Doctor Chang was stunned for a moment when he was asked.

Qingzhi said: "There are very few people in Dali who can afford to eat citrus, but there are not many people who suffer from this disease, why?" What is your explanation? ”

Imperial Doctor Chang was questioned again, and his brows were silent.

Qingzhi said again: "Since you have traveled from south to north, you must also have some understanding of this disease, this disease mostly occurs in autumn and winter, and rarely in summer, and the people who suffer from the disease are mostly poor people, and it is rarely seen in high-ranking officials and nobles. ”

She went on to explain: "Just because fresh vegetables and fruits are scarce and expensive in autumn and winter, poor people are used to eating pickled vegetables for autumn and winter, and in summer there are fresh vegetables and wild vegetables everywhere, so even poor people do not get sick in summer. As for the dignitaries, there is no shortage of vegetables and fruits in any season, so few of them suffer from this disease. ”

The Imperial Physician Chang was convinced, because he recalled his experience of traveling north and south before entering the palace, and it was indeed exactly the same as Qingzhi said, this disease was more likely to occur in autumn and winter, and it mostly occurred in poor people.

He sighed: "The old man believes it, it's really terrifying." ”

Qingzhi said in her heart, where is she just a posterity, is it a posterity.

In any case, I have been trained in modern medical knowledge.

Qingzhi said: "Chang Imperial Doctor praised it falsely, Xiaosheng is only a shallow learner, but he just happened to see an ancient medical book." ”

Seeing that she was knowledgeable but so humble, and that many people had saved face for him just now, Imperial Doctor Chang couldn't help but greatly praise her in his heart.

I was about to say something to her, but suddenly I coughed uncontrollably, and then said, "It looks like I've been injured by the wind too." ”

"Wounded by the wind?" Qingzhi asked suspiciously.

"In the past few days, some Japanese soldiers have been injured by the wind and contracted the wind cold, and the wind is indeed stronger on the march."

Aoeda speculated that his illness was caused by the soldiers' infection and not by the wind, and asked, "What are the symptoms of the soldiers who were injured by the wind?" ”

Chang Imperial Doctor said: "It's nothing more than ordinary wind chill symptoms, runny nose, weakness of limbs, fever, about the cold and heavy wind on the march, now everyone doesn't need to walk for the time being, and the number of people who should suffer from wind cold will gradually decrease." ”

Qingzhi asked again, "Who was the first wind chill patient in the camp?" ”

She speculated that it must have been those who needed to come into contact with people from the outside world on the march, such as logisticians, Tangbao cavalry, or their doctors.

"The first cold patient?" Imperial Doctor Chang pondered for a long time, "It's a logistics soldier who is specifically responsible for going to buy vegetables, and then a few days later, all the people who went to buy vegetables got a cold." ”

Qingzhi said: "Is it that after that batch of logistics soldiers, there are also wind and cold patients in the army?" ”

Doctor Chang said: "Exactly, the wind has indeed been a little cold these days. Now that we are settled, there will be fewer and fewer people with wind chills. ”

Qingzhi said: "Actually, it's not. I'm afraid there will be more and more. ”

Imperial Doctor Chang disagreed: "How can you say this? ”

Qingzhi said: "The wind chill mentioned by Imperial Doctor Chang is actually not caused by the wind, but caused by mutual infection. ”

The Imperial Doctor still disagreed: "What you said is a plague, it will kill people, but ordinary wind and cold will not kill people, and they will not infect each other." ”

Originally, Qingzhi didn't want to argue with him, but considering that the war was imminent, if there were more and more fever patients, he was afraid that he would be unable to meet the battle and cause countless casualties.

So she said, "Although it is not a plague, it is not to be underestimated, you and these soldiers are not suffering from wind and cold, but diseases that can be transmitted to each other. ”

Doctor Chang said, "What basis do you have?" ”

Qingzhi said: "Are those patients with fever the same tent the first to be infected, and then slowly spread to the surrounding tents?" ”

Doctor Chang said: "I have to investigate this to find out." ”

With so many patients coming to the medric's tent every day, he didn't know if they were in the same tent.

But he immediately remembered that there was once a tent where three people came together, and one of the soldiers said something like this: "Doctor, all the people in our tents have the cold, but none of the people in the tents on their side have any, is it because our tents are not tightly closed at night?" How do you keep your tent tight? ”

He replied, "Just press some dirt." ”

After thinking about this, he somewhat believed Qingzhi's words, so he said, "You mean, this wind chill is contagious?" ”

"Actually, their illness is not caused by the wind, but by a virus or bacteria, and viruses or bacteria multiply, so they can spread from person to person. ”

"Viruses and bacteria?" For him, this is a new word.

"That's it...... Pathogenic bacteria. She wondered if he would understand better.

"Sick King?"

"Yes, pathogens are tiny things that are out of sight."

"If they can make people sick, why are they called disease-causing kings instead of disease-causing villains?"

"Sick villain?" Qingzhi was stunned for a moment, and realized that he might not have heard of the word fungus, "If you want to call them disease-causing villains, it's okay." ”

"So you mean, there will be more and more patients?"

Qingzhi said: "If it is not controlled, there will be more and more." ”

"How much more?"

"In the first few days, it may be limited, and it will take a few days from one person to ten people, but as long as it spreads, it will spread very quickly, one to ten, ten to hundred, and a hundred to thousand. In a place like a camp, when soldiers gather, the spread will be even faster. It is highly likely that half of the population will be infected. ”

She continued: "When the war is coming, if there are more and more patients, it is very unfavorable for the war. At present, it is necessary to isolate all those who are sick, and those who are not sick must not contact each other, and each tent must not interact with each other, and the logistic troops will bring it to each tent when eating, so that the number of sick people can be controlled in a small range, and only then will it be possible to defeat the other side. ”

Imperial Doctor Chang said: "Since the matter is so important, I will quickly report to His Royal Highness the Prince!" ”

After speaking, he said to Qingzhi, "Doctor Kong, I'll see you later", and hurriedly rushed to Prince Xiao's tent.
