Under the guidance of the veterans of Youyang, the Ming army's process of crossing Dashuize was extremely smooth.

I heard from Zhang Zhuguo that there were many water bandits in this generation, but maybe I hid when I heard the movement of the army.

Although the water bandits were fierce, they bullied the passing merchants and ordinary people.

If you really fight against the army, you basically have no chance of winning.

Zhu Youlang would ask these veterans about the past from time to time.

From their mouths, Zhu Youlang learned some details that were not known in history books.

After all, what is recorded in history books is only a rough idea, and the life and death of ordinary soldiers like this will not be mentioned at all.

But to truly understand history, we have to start with these ordinary soldiers.

The Ming army was moving very fast. At this speed, they could walk out of the Dashuize in two days.

However, at this moment, the disease appeared, and the soldiers fell ill. Although the overall proportion was not too high, the consequences would be unimaginable if they did not curb them and develop according to this momentum.

Zhu Youlang and Li Dingguo went to inspect immediately.

First, it is to appease the soldiers, and second, it is to figure out what the disease is.

However, during the inspection, Zhu Youlang ordered everyone to use a piece of cloth to surround their mouth and nose to play a protective role.

After all, judging from the current situation, the possibility of infectious diseases cannot be ruled out. If it is transmitted from human to human, it will be very troublesome.

Zhu Youlang came to the vicinity of the sick soldiers, although Li Dingguo was still worried even though he was a few meters away.

The emperor is a body of a thousand gold, and his identity is so noble.

If something goes wrong, the consequences will be unimaginable.

The emperor really shouldn't have come to visit the patients in person.

However, at this point, Li Dingguo didn't have much to say, so he could only hope that the epidemic would not spread to the emperor.

After Zhu Youlang's careful understanding, all the soldiers infected with the disease had intermittent symptoms of chills, fever and hyperhidrosis.

This symptom is easily mistaken for wind and cold. It was not until Zhu Youlang discovered that some soldiers were pale and concluded that things were not that simple.

This is a sign of anemia!

If it’s just wind and cold, it won’t be anemia!

Zhu Youlang is not a medical student, but he also knows that this symptom is a manifestation of malaria. As for intermittent whole body chills, fever and night sweats, they are also manifestations of malaria!

Malaria is generally transmitted through mosquito bites.

The humid environment in the swamp is conducive to the reproduction and spread of mosquitoes.

It can be said to be a hotbed of malaria transmission.

In addition, the ancients had poor hygiene habits, and more than a dozen people lived together during the march, which often resulted in concentrated infections.

But malaria itself is not transmitted from human to human. The reason for concentrated infection is that mosquito bites a soldier infected with malaria and then bites a soldier who is not infected with malaria. These soldiers who are not infected with malaria will also be infected.

More than a dozen soldiers live in a tent, and often one of them is bitten and the rest is hard to escape.

The mortality rate of malaria is very high, and the consequences will be serious if not controlled.

Finally, Zhu Youlang is preparing to confirm.

"Do these ill soldiers have diarrhea?"

"Report to Your Majesty, this is true. You often get a few stomachs a day."

When Zhu Youlang heard this, he was almost sure.

All symptoms of the sick soldier are consistent with malaria!

"I know what kind of disease this is!"

When Zhu Youlang said this sentence firmly, Li Ding Guozhi was shocked.

The emperor actually knows medical skills?

"Get paper and pen."

Although the conditions in the swamp were simple, Zhu Youlang's eunuch still carried paper and pen.

Han Miao quickly took the paper and pen and served respectfully.

Zhu Youlang quickly drew a herb, which is stinky artemisia.

The so-called stinky artemisia is actually Artemisia sycamore.

The whole plant has an aroma, the stems are upright, with longitudinal patterns, slightly hard texture, and the overall appearance is dark green or brown-green.

The dry ground part is also called Artemisia annua.

Artemisinin is a treasure medicine for the treatment of malaria, and artemisinin is extracted from Artemisia agaricus.

"I ordered people to look for the wormwood I painted everywhere. This object can be used as medicine to treat this disease."

The ancients probably did not have the concept of Artemisia annua, so Zhu Youlang always said Artemisia annua.

When everyone heard the name of Artemisia delta, they were indeed confused.

Zhang Zhuguo approached and looked at it, and said in a harmonious voice: "What the saint said is stinky artemisia?"

Zhu Youlang naturally knew the alias and nodded repeatedly: "No, it's this name!"

"Then I understand. Why don't the saint assign some people to me and I will take them to find them."

Zhu Youlang thought about it and nodded in agreement.

Artemisia sacred flowers like to grow in humid environments, so there should be many of them in the water, otherwise Zhang Zhuguo would not recognize them at first sight.

While Zhang Zhuguo took people to find Artemisia, Zhu Youlang ordered all the soldiers infected with malaria to be isolated and a dedicated person would take care of them.

All the things they used were destroyed.

Although malaria is mainly transmitted by mosquitoes, if normal people import the blood of infected people, they will also be infected.

In addition, the soldiers gathered together and could easily cause secondary bites from mosquitoes.

As long as the isolation and protection work is done well, the spread of malaria will be controlled.

The most urgent task at the moment is to use Artemisia anthracite to treat infected soldiers as soon as possible and then leave the swamp as soon as possible.

This will completely get rid of the possibility of mosquito transmission.

Although malaria is terrifying, it is much better than plague.

At least malaria will not spread through droplets like plague.

At first, Zhu Youlang was worried that the soldiers in the army would be infected with the plague, which would be really fatal.

At the end of the 16th year of Chongzhen, a major epidemic broke out in the capital.

Historical books record bighead plague, which is believed to be a plague.

It's actually plague.

The plague lasted from the end of the 16th year of Chongzhen until March of the 17th year of Chongzhen, and it did not disappear until the weather warmed up.

When Li Zicheng broke the city, nearly half of the people in the entire capital died, like a ghost realm.

It was not until the Eight Banners entered the pass and entered Beijing that the terrifying big-headed plague ended completely.

As long as it is not plague!

In fact, plague was very common in the Ming and even the Qing dynasties.

The so-called major epidemic will inevitably occur after a major disaster, or epidemics will also occur after a large-scale war.

Although there are natural disasters and man-made disasters, it has a lot to do with the poor hygiene habits of the ancients.

Although this epidemic is not a severe infectious disease like plague, Zhu Youlang still reminds him.

In the future, soldiers must pay attention to personal hygiene protection.

For example, you cannot urinate and defecate in the tent and have to take a regular bath, and still need to make a lot of effort to implement the basic requirements.

Although it cannot achieve complete hygiene, it is still useful for preventing epidemics.

Zhu Youlang didn't want the Qing army to defeat them, but the epidemic defeated them.

Alas, I really don’t know how much effort Wang Henian spent when traveling through this swamp. Zhu Youlang now only hopes to lead his troops out of this danger as soon as possible!
