"John, how many days are you going to spend in Hamburg this time?"

After getting into the carriage, Koch asked expectantly. Through various means, Koch already learned about John's report on cholera in London, and was naturally very interested, so he was also very much looking forward to communicating with John.

"Three to five days."

After thinking for a moment, John replied with a smile.

It has been said that cholera is one of the most devastating infectious diseases, but it is also one of the best to treat. Isolate infected patients, avoid drinking raw water and cold food, and disinfect water sources, flies, and excrement of patients, so that the spread of cholera can be quickly controlled and eventually eliminated. For those who have been infected, a considerable number of them can be cured on their own, and if others can be given oral rehydration or intravenous rehydration in time to alleviate the symptoms of dehydration, most of the patients can be saved!

In terms of content alone, isn't it simple?

In fact, it is not difficult to do this, don't look at cholera in the future to be included in the ranks of type A infectious diseases, that is because it is very harmful, the speed of infection is very fast, really talk about the treatment method is really not complicated. If he did his best, John believed that one day would be enough for any doctor or nurse in the future to figure it out!

But for the 19th century, this knowledge was very "cutting-edge"!

Needless to say, the discovery of Pacini was really discovered by influential people by Vibrio cholerae ten years ago! In the past ten years, it has also been a critical period for miasma theory and bacteriology, and the traditional conservatives have been fighting against Koch and others every day, insisting on retaining their last glory. Moreover, given the level of technology and infectious disease theory in this era, Koch could not completely prove that Vibrio cholerae was the root cause. Otherwise there wouldn't have been so many naysayers......

So John, after careful consideration, set aside plenty of time.

In the course of a few days, John had to spend time convincing Koch and others not only to leave the methods of cholera prevention, control and treatment to them! After all, controlling cholera is not a simple task, and it requires isolating sick people, disinfecting water sources, and spreading awareness about prevention and treatment measures, which is not something that anyone can do. Even Koch can't do it, you have to rely on the power of the Hamburg city government! Especially at a time when people and even physicians are desperately lacking in knowledge of infectious diseases, it takes a strong figure like Koch to persuade the government to implement the coercive measures that John needs, and only then can these ideas that are ahead of his time be realized!

After that, of course, he will leave the city of Hamburg as soon as possible and go to Berlin, which is relatively safe, to join Anna!

"Three to five days?"

After listening to John's words, Koch couldn't help but frown.

For him. Of course, the time of these days is too little, after all, every time I go to the epidemic area to study various infectious diseases, is that time not more than a month? So hearing John say that he could only stay for a few days, Koch didn't feel very comfortable in his heart. But he couldn't say much, he was a surgeon, and he wasn't German, so he really couldn't ask for too much......

"Don't worry, Professor!"

It seemed to see Koch's displeasure. John hurriedly explained with a smile: "Our research on cholera is very mature, and a few days is enough time for me to understand the cholera epidemic in Hamburg. And after discussing the prevention and treatment measures with you, it should surprise you! ”

"Oh? I'm really looking forward to it. ”

John's words made Koch's eyes light up, and he couldn't help but speak.

In the past few days, Koch has learned a lot about John's cholera theory, or infectious disease theory, but limited by the medical level of this era, Koch is certainly not sure whether John's theory is correct. But at this time, as long as there is hope, you can try it, right? Moreover, not to mention that John's theory firmly supports Koch's theory that Vibrio cholerae causes disease, John? The name Huntelaar is enough for Koch to express his attitude - John's name can be said to have skyrocketed in the European medical community today. Especially in the field of surgery, he is almost on an equal footing with Liszt.

With such a supporter, Koch certainly knows what to do......

"Don't stay in a hotel this time."

In anticipation, Koch said seriously: 'Although this is not Berlin, an old friend has offered me a house that will be enough for you to live together...... The hotel is not very safe now! “

"This ......"

Turning his head to look out the window, John's heart was a little tangled.

It's not the first time he's been to Hamburg, but there's never been a time when the streets were so deserted as today! Occasionally, I saw a few people or horse-drawn carriages, all of them coming and going in a hurry, and almost no one stopped on the street, as if the liveliest port city in Germany was half dead all at once! This is a typical plague city, people are absolutely reluctant to go out unless they are forced to do so, so Koch's words are indeed very reasonable, after all, hotels are indeed one of the most dangerous places!

But......

"At this time, I'm afraid it's more dangerous to live with Koch, right?"

Turning his head to look at Robert, who had a sincere face? Koch, John couldn't help but complain secretly in his heart. One of the originators of bacteriology has a great reputation in the history of medicine, probably second only to Pasteur in France! Of course, this is an honor that Koch deserves, but he naturally pays a lot for this high honor, one of which is the constant threat that comes head-on. In this era, as long as there is a major epidemic, Koch will inevitably follow, but compared with other unlucky doctors of his time, Koch's luck is much better, and he does not get any deadly infectious diseases.

It must be very dangerous to live with him in these extraordinary times!

But......

In any case, Koch was in the limelight at this time, and in addition to Petertenkov, who was "rightfully the best cholera expert", Koch was now one of the most relied on experts of the Hamburg city government for his outstanding achievements in bacteriology and his record in "discovering" Vibrio cholerae. By his side, he should have the most advanced research conditions in Hamburg at this time, even if it doesn't make any sense to John at all, but at least it can test the theory of the future, right?

If you convince Koch first, it will be possible to convince others!

So after thinking about it for two or three seconds, John finally nodded and smiled, "Then I'll trouble you, Professor!" It's an honor to work with you in the future......"
