Infectious diseases are a must for any medical student in the 21st century.

With the progress of social health conditions and the development of medical technology, infectious diseases are no longer the most important diseases in human society, at least for China and other developed countries in the future. But no one dares to ignore the harm of infectious diseases, so after SARS, the originally hard-pressed prevention majors in major medical colleges and universities have completely turned into serfs and sang, and the inconspicuous epidemic prevention station has also broken into a butterfly, with the lofty name of CDC.

Therefore, in the future of China's legal system, the law on infectious diseases will become more and more important.

In the provisions of the law, infectious diseases are divided into three categories: Class A, Class B and Class C, of which Class A infectious diseases are naturally the most serious diseases, which must be reported within two hours after discovery, and then medical institutions and CDC will immediately take a series of prevention and control measures......

Plague and cholera are the only two Class A infectious diseases.

Many people may not have much feeling about the medical term plague, but if we talk about the "Black Death", I believe those who know the history of Europe will understand. In the 14th century, the disease buried almost half of Europe, and in the following hundreds of years, it raged around the world, and the degree of harm is definitely comparable to that of smallpox, the "killer of civilization"! The difference is that smallpox is the only infectious disease that has been eradicated by humans, and the children of the future will hardly hear of it, but the plague still exists......

Cholera is the "king of the same word" that can be compared with plague and smallpox among infectious diseases!

So when John heard from Ehrlich about the cholera epidemic in Hamburg, Germany, he was shocked! If it were a hundred years from now, John would not have heard of cases of plague or cholera, after all, the excellent medical conditions and strict prevention and control measures of modern society would have had an immediate effect. But more than a hundred years ago this year. Even if he is a physician who has crossed over from the afterlife, he still has to be distracted by this terrible disease!

The "world disease" of the 19th century is no joke!

In the 100 years from 1817 to 1923, there were six cholera epidemics, which cost India more than 30 million lives alone, after Ehrlich informed John of the news. He immediately found in the corner of his memory the impression of the cholera epidemic in Hamburg in 1892: the water system was polluted, and 8,606 people died in the end - in Europe, in Hamburg, Germany!

“…… Damn it! ”

After seeing off the worried Ehrlich, John closed the door and cursed fiercely!

John had all the memories of his past life in his mind, as long as he had seen or heard, but he couldn't pay attention to it if he didn't deliberately look for it. After all, the human brain has a limited degree of development, and forgetting is also a self-protection mechanism of the human body in a sense, so it is impossible for him to let so much information occupy his memory space. But at this moment. John regretted that he hadn't searched his memories in advance. According to their plan, after a week's stay in London, they will depart for Germany, with the first stop being Hamburg, just across the water. But now that there's a serious cholera epidemic in Hamburg, how can his original plan go ahead?

"John, what's going on?"

Hearing her husband's swearing, Anna immediately came over with concern.

"This ......"

After a moment's hesitation, John simply told Anna the news.

"What? Cholera? Germany? ”

After hearing John's words, Anna exclaimed. The little face suddenly turned pale! As a native of Europe, how could Anna not understand the horror of this disease? Now I heard that there was a cholera epidemic in Germany. Naturally, I was worried about my parents and family for the first time!

"Rest assured, this cholera epidemic is confined to Hamburg."

Holding his wife's little hand, John comforted him gently. At this time, he had to thank the poor transportation conditions at the end of the 19th century, and it was not easy for people to travel far away, so naturally there was very little communication between different places. At least for the average person, the cost of going to another city is too high. Otherwise, if there is a huge flow of people as in the future, the harm of infectious diseases will be even more unlimited.

But even with John's comfort, the temperature of Anna's palms quickly dropped.

That's cholera!

Over the past few decades, the disease has swept Britain, France, Germany, and even Europe, claiming millions of lives. And until now, doctors haven't even figured out why it happened, let alone treated it. So after hearing this news, how could Anna be at ease? At the thought of her parents and family who stayed in Berlin, her palms were quickly occupied by cold sweat while shaking incessantly......

"Damn it!"

Feeling the temperature and humidity of his wife's palm, John couldn't help but curse again in his heart. Of course, he knew how long his wife had been looking forward to coming home this time, but in this case, he couldn't let Anna risk returning home, and the next two days would be really difficult......

……

Listening to Anna's steady breathing, John didn't feel the slightest sleep.

It took him more than an hour to calm Anna down, and finally fell asleep exhausted, but how to solve the problem in front of John still gave John a headache. More than 8,000 people died in a city, and it was a German city at the end of the 19th century, so you can imagine how terrible this plague epidemic will be! In this case, John would never have allowed Anna to take the risk, but ......

"If you wait for the Germans to take control themselves, when?"

Come to think of it, that's all John has a headache.

It was only in 1883 that Vibrio cholerae was first discovered. Ten years ago, when the fifth pandemic of cholera began, Koch, who had already made a name for himself, was sent out to help other countries, so the originator of bacteriology followed the footsteps of cholera, from Egypt to India, and after dissecting dozens of patients, he finally discovered the culprit of cholera - Vibrio cholerae, which was not so straight, a little crooked, like a comma. The discovery of the pathogen for this terrible disease is an epoch-making achievement and one of the brilliant points in Koch's life.

Merely......

At that time, Koch was not so influential, and the medical technology of this era was really too backward, so whether Vibrio was the cause of cholera was still inconclusive, at least in 1892, Koch was unable to convince more doctors to accept this idea. After all, bacteriology was just beginning in its infancy, and Koch had strong competitors in front of him, whose views seemed to be more in line with traditional medical theories.

"Damn it!"

This is the first time John has cursed this sentence in his heart today. If this cholera is really allowed to develop on its own, Anna's disappointment is not to mention for the time being, is John also waiting in England?

"Hoo ......"

Exhaling softly, John frowned, his eyes flickering frequently. (To be continued.) )
