Zhao Yu gave Hao Yuntong a big favor, of course, there was a meaning to win him over, but it was not all.

Hao Yuntong can be said to have been raised by him, although his ability is limited, he has always been conscientious, serving before and after the saddle. And those 'newcomers' despise and exclude them, in Zhao Hao's view, it is to slap themselves in the face and embarrass themselves, but now is the time to employ people, and they can't all be beaten to death with a stick. Therefore, consolidating its position with a prescription can be said to be a small profit.

At the same time, Zhao Yu strictly ordered Hao Yuntong to keep the prescription secret, and there was another reason for strictly prohibiting the spread. Miasma has been a feared presence since ancient times, and the susceptibility to malaria, low cure rates, and high mortality rates are often prohibitive, which is why China's Lingnan region has been slow to be undeveloped. The same is true globally, as is Africa, which is also a region with a high incidence of malaria.

In the 15th century, when Portugal was in its prime, King Manuel I sent an expedition up the Gambia River in West Africa to explore the "dark heart". However, only one member of the expedition returned unharmed, leaving all the others on African soil. So that the historian of later generations John Wang? Morality? "God has sent an angel wielding a sword of fire of deadly fever to prevent us from entering the fountain of this garden, from where the river of gold flows into the sea that we have conquered many times," Baros lamented. ”

For hundreds of years, malaria kept European adventurers out of the interior of the "Dark Continent" until the Europeans extracted quinine, a cure for malaria, from the cinchona tree in the Americas. Even so, by 1900, a quarter of Africa's interior remained unexplored. Dean? Swift once described the dilemma of mapping this dark continent this way: "On the map of Africa, geographers fill in the gaps with wild animals. Therefore, for the uninhabitable hills, elephants were filled in to replace the lack of towns. ”

Therefore, malaria is not only a malignant disease that kills mankind, but also can stop invaders. And now that the Mongols have set foot on the land of Lingnan, their next step will be to enter Hainan Island. Zhao also knew that the Mongols would launch a war to conquer Cochin and Champa within a few years, and although the two countries were forced to become vassals, only more than 10,000 of the tens of thousands of troops sent out came back alive, and the rest were dumped in the tropical jungle, and malaria was the biggest killer.

Zhao Yu pondered that if he made the treatment for malaria public, the Mongols would definitely know about it. And Artemisia annua is a plant everywhere in the south of the Yangtze River, and it is not a scarce resource, and there is nowhere to start if you want to control it. While he benefited mankind, he also aided the abuse, indirectly helped the enemy and eliminated himself. Therefore, the safest way is to cut it off from the root, so that others cannot know this secret, and at the same time fulfill the friendship with Hao Yuntong. However, he still felt a little apprehensive in his heart, feeling that he was too narrow-minded and did not think about the health of the vast number of people on the earth......

"Dean Hao, although the treatment of miasma with Artemisia annua is effective, it is still difficult to avoid transmission and cure it, so you have to do a few things!" Zhao knew that malaria was transmitted through mosquito bites, so only by cutting off the route of infection could more people be infected.

"Your Highness, just command!" Hao Yuntong just got a big gift, where is there a road that is not satisfactory, Shi Li said.

"Miasma is caused by mosquito accumulation, so the only way to avoid infection is to try to get rid of mosquitoes." Zhao Yu thought for a while, and tried his best to express his meaning in a language that the 'ancients' could understand.

"Your Highness, there are trillions of mosquitoes, if you want to get rid of all of them, your subordinates will never be able to do it!" Hao Yuntong immediately made a bitter face when he heard this, the number of mosquitoes was huge, flying around, coming and going without a trace, how could he have the ability to get rid of them all.

"Don't worry, this king hasn't let you exterminate all the mosquitoes in the world!" Zhao Yu smiled, and said in his heart Don't talk about you, even if people die, mosquitoes may not be able to die, and it would be a joke to completely eliminate it.

"Oh, what does His Highness mean ......" Hao Yuntong secretly breathed a sigh of relief, secretly glad that His Highness understood the matter and did not let him do this big thing.

"The king asks you if you have a prescription to repel mosquitoes in case you are bitten by them?"

"Your Highness, this is not difficult, the subordinates know many kinds, as long as they are made into sachets, they can expel mosquitoes. Prescriptions can be served at any time! This is relatively simple, Hao Yuntong replied immediately.

"Is there any other way to avoid mosquito bites?" There is no winter in Hainan Island, there are mosquitoes in all seasons, and now it is the rainy season where mosquitoes are more rampant.

"Your Highness, you can equip the soldiers with curtains to prevent bites, and you can also repel mosquitoes by burning wormwood, and some flowers and plants will also drive mosquitoes away!" Hao Yuntong thought for a moment and replied.

"Very good, you can write a note when you go back, report to the department, and this king can implement it after convening the assembly of all departments, and it may fall on your medical hospital at that time!" Zhao Yu said.

"Does Your Highness mean that it is modeled after the prohibition of defecation everywhere in Jiazi Town?" Hao Yuntong asked with a smile.

"Exactly, this king charges, you fire the cannon, and then we will order the whole army to implement it!" Zhao Hao also smiled, it seems that this guy still has some political acumen, and he can make sense at all.

"The subordinates obey the order, if His Highness does not give orders, the subordinates will retire!" Hao Yuntong got the plan and bowed down to salute.

"Then it's hard work!" Zhao Yu waved his hand to signal that he could go......

The next day, Hao Yuntong, the director of the medical institute, wrote to the Department of the Ministry of Medicine that the miasma was raging in the army, so that hundreds of soldiers were infected with the disease, and at this time, the people were panicked and the army's morale was turbulent, and asked His Highness to take measures as soon as possible to prevent the spread of the miasma and stabilize the morale of the army. After receiving the report, Zhao Yu summoned the heads of various departments to the mansion that night to discuss and agree on a solution. Hao Yuntong first said that the medical bureau had found out that the miasma epidemic was caused by people being infected with miasma after being bitten by mosquitoes. At present, while actively treating the sick, it is necessary to take precautions to prevent soldiers from continuing to be infected.

Everyone present knew how serious the consequences of the plague epidemic were, and immediately agreed that the medical institute should take charge of the epidemic eradication work, and all departments worked together to agree on a solution. First, prevention is the mainstay, supplemented by treatment; 2. The anti-mosquito sachets prepared by the Medical Bureau, after being made by the Metropolitan Hospital, are quickly distributed to the soldiers and must be carried day and night; 3. The General Bureau shall allocate special funds for the production of curtains and distribute them to the whole army; 4. Remove stagnant water from the camp area to prevent mosquito breeding. At the same time, all feasible measures should be taken to drive away and eliminate mosquitoes; 5. Infected persons are promptly isolated and handed over to medical hospitals for treatment; 6. The whole army must comply with it, and those who violate it will be dealt with by military law...... (To be continued.) )
