    For officials of any dynasty, official positions are their second life.  When Liu Jingren heard that Sun Yuanqi was going to murder his second life, his enthusiasm for work immediately became as strong as a surge of energy.

    Early the next morning, as soon as Sun Yuanqi got up, Liu Jingren came over to report: "Sir, the new site of the nursing home has been found!"

    "oh?"

    "Xia Guan found an inn on the outskirts of the city. It has more than fifty rooms, complete with beds, tables and chairs. Due to the recent severe epidemic, there are few guests, so we can borrow it." Liu Jingren was afraid that Sun Yuanqi would not believe it, so he explained in detail.

    Sun Yuanqi was overjoyed, and it was inevitable that he would be rewarded generously.  Not caring about breakfast, he immediately ordered people to invite Wu Liande, doctors Yao Suner, Zhao Jinghui and others to discuss the establishment of a more formal infectious disease hospital on the new site. Doctors Yao and Suner were responsible for treating patients, and Wu Liande was responsible for finding the source of the disease and infection.  Methods, Zhao Jinghui and others studied germs and anti-disease drugs. As for himself, he took the initiative to take charge of isolation, disinfection, aftermath and other matters.

    After everyone dispersed, Sun Yuanqi had a few mouthfuls of breakfast and was about to lead the volunteers out to supervise the martial law in the city. The concierge came to report: "Sir, there are two foreigners asking to see you."

    They have very good noses. I just arrived yesterday afternoon, and they came to my door today.

    Both of them have business cards, one says "Dr. Kitasato Shibasaburo, Director of the Private Kitasato Institute of Bacteriology, Japan", and the other says "Dr. Hafken, Director of Harbin Russian Railway Hospital". It seems that they are Japanese and Japanese respectively.  The chief medical officer of Russia and Russia¡¯s epidemic prevention.

    Technocrats are simpler after all, and they arrived at the epidemic area earlier and have a deeper understanding of the epidemic, so they can communicate with each other.  Thinking of this, Sun Yuanqi said: "Please come quickly!"

    Kitasato Shibasaburo is a short old man in his fifties, and Hafken is a tall man in his early thirties. They both paid enough respect to Sun Yuanqi.  After the greetings, Sun Yuanqi asked directly: "Both of you are experts in infectious diseases. What do you think of this epidemic?"

    Because of his in-depth research on Vibrio cholerae, Yersinia pestis and other bacteria, Kitasato Shibasaburo enjoys a high reputation in the academic circle. Huff did not dare to neglect and respectfully asked him to express his opinion first.  Kitasato pondered for a moment and said carefully: "In 1894, the plague broke out in Hong Kong. My colleague Dr. Yintong Aoyama and others went to the affected area to conduct field investigations. We discovered and isolated Yersinia pestis from rats, thus confirming that rats were the culprits in spreading the plague.  .This time I was entrusted by the South Manchuria Railway Co., Ltd. to investigate the cause of the disease. After arriving in Fujiadian, I immediately hired people to capture mice in the hope of finding Yersinia pestis in the mice. However, after dissecting hundreds of mice, no trace of the disease was found in the mice.  Yersinia pestis was found on my body. So I have some doubts about whether the infectious disease currently circulating is the plague."

    After listening to the translation, Sun Yuanqi was a little confused: "Mr. Kitasato, you are an expert in the study of Yersinia pestis. You only need to dissect the remains of the deceased and compare the differences between the two germs, and you can determine whether it is plague, right?"

    Kitasato Shibasaburo bowed and replied: "I'm really sorry, I haven't had the opportunity to dissect the body so far, because no Japanese expatriates have been infected with this disease yet. There are many people in your country who have died from infection, but your country's law strictly prohibits the destruction of corpses.  , as a foreigner, I can¡¯t go beyond it.¡±

    Sun Yuanqi asked Hafken again: "Dr. Hafken, what is your opinion?"

    Havken replied somewhat complacently: "Unfortunately, but also somewhat fortunately, many Russian expatriates in Riverside Hall are infected with this disease. After careful testing, I can now be completely sure that this infectious disease is the plague!"

    Kitasato Shibasaburo wondered: "Since it is plague, why didn't I find Yersinia pestis in the mice?"

    Hafken blinked his blue eyes: "Perhaps you are as unlucky as Sir Newton, and the hundreds of mice you dissected happened to be healthy."

    Newton was a great scientist, but sometimes he was unlucky and made mistakes.  In 1666, 23-year-old Newton wanted to prove through experiments that different substances have different refractive indexes, so he combined glass and water and measured the difference in refractive index between the two.  Unfortunately, the glass he chose has the same refractive index as water.  So Newton deduced that all transparent substances have the same refractive index.

    He also excitedly told this result to a friend Lucas who was very interested in optics.  Lucas didn't believe it and went back to redo the experiment.  He chose the difference between glass and Newton, and naturally came to the opposite conclusion: glass and water have different refractive indexes.  When Lucas told Newton the results, Newton was so stubborn that he didn't even bother to repeat the experiment.

    Given Newton¡¯s reputation, everyone accepted his wrong conclusion.  It was not until Newton's death that people discoveredThis conclusion is wrong.

    This story of Newton is familiar to scientific researchers.  After listening to Hafken's explanation, Kitasato Shibasaburo became suspicious of his own dissection results and thought to himself: Could it be that all the mice I dissected came from the same nest?  I have to go back and try to catch more mice!

    Sun Yuanqi said hesitantly: "Both of you are experts in plague research. As a layman, I would like to ask you a few questions: First, are rats the only medium for spreading plague? Second, can plague spread between people?  Transmission from person to person? Third, will the plague mutate, or will there be more than one type of plague?"

    Kitasato Shibasaburo replied: "Based on current research, Rattus japonica, Rattus norvegicus and Rattus nigra are the most important sources of human plague. The main transmission of plague between rats and humans is by rats.  Fleas are the vector. When rat fleas suck rat blood containing pathogenic bacteria, and then suck human blood, the pathogens will be injected into the human body. This 'rat ¡ú flea ¡ú human' transmission method is the main mode of transmission of plague. And plague in humans  Human-to-human transmission only occurs when an abscess ruptures or when a flea sucks blood. As for whether the plague will mutate or what type of plague it is, I have not seen any scientific reports yet."

    Sun Yuanqi said: "Theoretically speaking, it is already winter and the rat activity has decreased, so the epidemic should tend to slow down rather than have a large-scale outbreak. But in fact? The Fujiadian epidemic is getting worse. Doctors at our nursing home have observed  It was found that this infectious disease can be transmitted through droplets. Therefore, we suspect that this may be a new infectious disease."

    Havken¡¯s words were quite disdainful: ¡°Dr. Johnson, medicine is the same as physics and chemistry. Correct conclusions should be based on scientific experiments and rigorous analysis, rather than relying on observation and conjecture.¡±

    Sun Yuanqi said: "If the existing conclusions cannot explain the objectively existing phenomena, shouldn't we doubt the conclusions in turn?"

    Haffken retorted bluntly: "The objective phenomenon now is that I found Yersinia pestis in the blood of infected people!"

    Seeing that the atmosphere was a bit tense, Kitasato Shibasaburo quickly interjected: "If it is really a plague, then the most important thing we should do now is to mobilize the entire city's residents to capture rats and kill fleas."

    Haffken said: "If your government can give each rat a reward of 2 copper coins, I believe the epidemic can be effectively controlled in the short term. Moreover, I think you should not restrict the activities of citizens. On the contrary, only by moving as much as possible can we  Safe from fleas and rats!¡±

    Sun Yuanqi then understood the purpose of their visit: "Thank you both for your suggestions. I am currently organizing researchers to study the epidemic. If your suggestions are confirmed to be effective, I will seriously adopt them."

    Hafken shook his head: "Dr. Johnson, as the main person in charge of this epidemic prevention, you are not only to prove your own point of view, but more importantly, to control the epidemic in time and save more lives. Don't be suspicious because of you.  and stubbornness, and more people will be infected with the plague and die!"

    Sun Yuanqi said: "In fact, we are implementing effective epidemic control plans, including establishing a relatively complete infectious disease hospital, actively searching for the source of the disease, distributing masks to healthy people, isolating the infected, cremating the deceased, and  Martial law and disinfection are implemented in urban areas.¡±

    Havken shrugged: "There is a saying in China that if you want the spring water to be clear, you should control it from the source, otherwise all efforts will be in vain. The same is true for controlling the epidemic. As we all know, the only way to control the epidemic is to eliminate it.  Rats. You focus all your energy on the minutiae, which will only make things worse. I think the effect should be better if you spend the money you spend on masks and disinfectants on offering bounties to catch rats!"

    Sun Yuanqi said: "Thank you, Dr. Hafken, I will seriously consider this suggestion."

    Having said this, Kitasato Shibasaburo and Hafken had no choice but to stand up and leave.  Before leaving the house, Haffken suddenly turned around and said: "By the way, Dr. Johnson, when my uncle was in charge of the plague prevention and control work in Mumbai, India, he developed a vaccine that can prevent plague. Our hospital still has some, if you need it.  , some can be transferred.¡±

    "Oh? How much does one cost?" Sun Yuanqi was really excited: There are so many volunteers participating in epidemic prevention work. If something goes wrong, it will be a huge loss to the school.  If the price is right, you can purchase a batch for spare use.

    "Two hundred and twenty taels of silver each. If the demand is large, we can give you a discount." Hafken said with a bright face.

    Sun Yuanqi took a breath: In addition to being a robber, he is also a medicine seller!  I dare to buy two hundred and twenty taels of silver for one vaccine, which is more money than robbery!

    Of course, the price of vaccines has always been on the high side of medicines, let alone in the early 20th century?  What's more, in an area hit hardest by the plague?  You must know that during the Anti-Japanese War, a box of penicillin was worth a gold bar on the black market!

    Sun Yuanqi took a long time to make up his mind: "Okay, give us five sticks first, no, ten!"

    But I thought in my heart: Our country of porcelain is the ancestor of copycat technology. With these ten vaccine samples, if you don¡¯t believe it, you won¡¯t be able to create high-quality imitations!  (To be continued.
