If human beings will perish within the next hundred or thousand years, what will it cause? Resource depletion? nuclear war ? The answer may be viruses.
This kind of prediction has been frequently mentioned in the past decade. Although the speakers are all experts or authoritative scholars, people do not seem to be interested in it at all, and they only feel that these questions are too far away from them.
Until the end of 2019, a virus called "COVID-19" swept the world, causing the economic development of almost all countries to stagnate or even regress. The lives of countless people have been greatly affected by it. In China, we call it the "new coronavirus".
The total number of deaths from the new coronavirus worldwide is more than 6 million, which is caused by untimely prevention and resolution in many foreign regions. Although the death toll remains high, in the face of such super-scale infectious diseases, the mortality rate of new crown is less than 2%. Especially in China, due to strict prevention and control and treatment measures, the death toll has been firmly restrained under such a large population density and base.
You should know that compared to the predecessors of the new crown, the three most famous gods of death in human history - Black Death , smallpox, and influenza, the new crown virus is really weak.
Even the mask that we are essential on everyone’s face is also the first time it was used on a large scale during the influenza in 1918, and since then it has become the first line of defense in the fight against the epidemic.
Perhaps only by looking back at history, in the face of hundreds of millions of people who died in severe pain, can we truly realize the terror of the virus and firmly resolve to fight it to the end.
1347, in Europe, a great "jihad" had just come to an end. When the Catholic Church of Rome learned that its holy land Jerusalem was occupied by Islam , it immediately pulled a large number of Western European countries to start up to nine battles, known in history as " Crusade ".
After the war ended, the army returned to Europe, but this triumph became the prelude to a huge disaster, because some of these soldiers brought back a deadly virus - Plague , also known as the Black Death.
This is just a saying, and there is another saying is because of the virus brought by the merchants of Mediterranean .
At that time, Europe's maritime commercial trade was extremely developed, and the Mediterranean was a necessary transportation hub. After the virus was brought over, it spread across Europe along other merchant ships.
In short, no matter which source it was, at that time, plague , which originally only existed in Central Asia, was indeed introduced to Europe and broke out in an instant.
killed more than 25 million people in four years, accounting for one-third of the entire European population at that time, and was a disaster of extinction.
Pelvic bacteria, as the name suggests, this bacteria generally use rodents such as mice as hosts.
. The mice are very resistant, so they can carry viruses and spread everywhere. At the same time, the flea on the mice will also be infected, and then the bacteria will be transmitted into the body after biting humans.
It was the Middle Ages, and it was a period of rapid development in Europe. Many famous cities rose to the ground and their population continued to increase.
But as we all know, Europeans rely very much on commercial trade, and many materials must be imported from overseas, so commerce has become the foundation for the survival of many countries. Many places even do not simply plant food and serve maritime trade.
Today, we can see the aristocrats, manors and art of medieval Europe, but behind these glamorous scenes, the lives of their grassroots people are in a mess.
Objectively speaking, compared with China in the same era, their lives can only be described as "dirty, messy, and poor".
European cities were just emerging at that time, and the structure was very simple. The most considered in design might be the function of defending enemies. As for systems such as sewage discharge, it can be said that there are almost no systems, and related public facilities do not exist at all, because the government thinks that hygiene is a personal problem, so it is enough to solve it yourself.
So the solution for Europeans is very simple - not to solve it.
They can say that they have no concept of hygiene at all. Due to the inadequate freshwater resources, inadequate personal awareness, and the poor people at the bottom, Europeans are almost in a barbaric period.
They only take a shower once a long time, all the garbage is thrown at the door, and the urine and defecation are solved at will. The roads in the city have not been repaired, and basically they are messed up after a few tramplings.
And Westerners, especially men, have very strong hair in their bodies and are prone to bacterial growth, just like they invented perfume to cover up body odor.
With the rapid growth of the population, cities are becoming more and more crowded, but sanitary conditions have not been enhanced accordingly, which has led to the worse and worse urban environment.
The most important problem is that in Europe at that time, the concept of medicine was basically in its infancy. The pathogen of plague, Bacillus pestis, was not discovered until 1894. After being suddenly attacked by this virus in Europe, they had no idea what disease they were infected with and how to cure it.
In 1347, the plague suddenly appeared in Central Asia, but it was deserted and remote, with a small population, and the virus could not spread at all.
But this year was the time when the Mongolian Iron Cavalry collided with Europe again, and a small city next to Black Sea was surrounded.
But at this time, the plague began to become popular in the Mongolian army, making siege very difficult. Mongolian adopted a strategy of killing two birds with one stone - throwing the corpse of the dead infected person directly into the city with a catapult. This is completely the earliest biochemical weapon used by humans.
Then, Kafa was quickly destroyed by the plague, and the people in the city fled one after another. The plague virus carried by some of them spread in Europe, and the merchant ships that kept coming and going at sea every day provided the greatest convenience for the virus.
Italy was the first to be captured, the number of infections increased day by day. The patients were dizzy, fever, dry cough, and swollen lymph. After becoming more and more serious, black spots began to appear on their skin, and eventually died with the complete collapse of their internal organs. The fastest case, it only took one day from infection to death.
For this completely unknown virus, the body will rot and turn black after the patient dies, so it was called the "Black Death" at that time.
Constantinople is a thousand-year-old capital and the economic and cultural center of Europe. The trade routes radiated from here can almost lead to all parts of the world. After the plague broke out in this city, it quickly spread along countless routes to the entire Europe and even Africa. Britain, France, Russia...
This plague came too quickly and spread too quickly. Moreover, for the underground medical environment in Europe at that time, it was almost impossible for people to be cured once they were infected.
Those at a loss doctors are still using old-fashioned smoky, bloodletting, vomiting and other therapies. Later, they even wrapped the whole person with wax and directly burned the person's lymphatic lumps with high temperature flames.
However, it is useless. The terrible plague cannot be expelled by these funny methods. The number of deaths is increasing. The living and dead will become the source of continued spread.
In those areas that have been captured by the epidemic, people will draw a big white letter "P" on the wall, but later, this big white letter can be seen almost everywhere.
At that time, the scale of the dead was unimaginable. In Italy, the first country infected by the virus, in the largest and most prosperous city of Florence, more than 80% of people were infected, and thousands and thousands of people continued to die every day.
Some people were hiding at home in great panic. After being discovered, they had already rotted and smelly and died for a long time. The body was dragged to the suburbs by vehicles like a hill.
The information transmission at that time was very slow, and Europe was unable to achieve strict population and household registration management. The government had no way to unify the control of the situation, especially in the early days, many people did not know what was happening.
Perhaps only I heard that people were dead everywhere, so I began to escape from the city and the countryside, and from the coast to the mainland. The Black Death followed these people to further expand the scale of infection.
Just think about it, with the current government strictly controlling the situation, the masses actively cooperate in isolation, everyone wears masks and performs accounting, the epidemic still occasionally repeats itself, but in Europe at that time, doctors were helpless and the government was completely unable to grasp the situation. People took the virus everywhere, and the impact caused was simply devastating.
In the face of an astonishing number of deaths, the people finally took some measures. They realized the spread of the disease and began to burn patients' bodies and items that might carry germs. The exchanges between cities were cut off, and many areas began to implement small-scale isolation policies.
, but the effect of doing this is very meager. After all, when you know nothing about microorganisms , you never realize that this disease is caused by things like mice and fleas.
There is only despair left in people's hearts. In Europe, where religious beliefs are strong, many people regard this plague as a punishment brought by God. They are powerless to resist and can only pray. Some people whip themselves every day to try to atone for God.
When there was no way, I simply put all the blame on Jews and pagans. This is a very typical practice in the Middle Ages, saying that these people brought plague from the demons, so they started massacres everywhere.
Because there are too few doctors and it is useless, the priests and pastors in the churches are shrouded in the environment of ignorant thoughts, holding the Bible in their hands, hanging crosses, walking among the sick, and carrying out salvation in the name of God.
But the means of salvation are actually prayer and baptism. They firmly believe that these sick people are all because of their sins. As long as their sins are forgiven, they will get better.
Of course, these ideas are of course useless in the face of the Black Death. Not only that, these clergymen were infected in large numbers and died.
At that time, Europe was under the rule of the unity of politics and religion. These people were to a certain extent semi-civilians. Once they died, the government's control became even weaker and the people were completely confused.
Not only the epidemic, but all kinds of riots, thefts, robberies, etc. have emerged. The order of the entire society has reached the brink of collapse. If it continues, the extinction of Europe is not unforeseeable.
But in 1352, the Black Death, or the plague, disappeared in an instant. People suddenly found that there were no new infected people. Everyone walked out of their homes and ushered in a new dawn.
Until now, humans have not figured out why the Black Death disappeared back then, but the most reasonable speculation is that this virus is too fatal and spreadable.
Because people are the host of the virus, if they die too quickly, they will also block the spread of the virus, and all those who survive have produced antibodies.
This great plague that swept Europe and turned many cities into empty cities is coming and going with the wind, but the far-reaching impact it has left is not only the huge loss of population, but also the impact on religion.
In the disaster, those who claim to be the apostle of God have no way to stop the plague. After facing the most terrifying death, people feel that they should live in the present and enjoy it. In this environment, the famous " Renaissance ", " Great Navigation ", and " Industrial Revolution " happened one after another.
Now, we don’t know when the epidemic will end, but we must definitely recognize its danger. The war between humans and the virus is a protracted war. Today’s medical technology has provided us with a very powerful weapon, but the virus is also constantly mutating, and everyone should be prepared for danger in times of peace.
