In fact, human history does not know how many times there has been a new crown of this virus, just that the ancient people did not know it at all.
The ancients, unlike today, had very poor medical care.
Many ancient people also just got a cold and somehow died.
For example, Qingwen in the Dream of the Red Chamber, got a cold and tossed it around, and died.
This kind of thing was very common back in the day, especially among the elderly who were at risk when they got a cold.
For example, Jia Mu, the mother of the Dream of the Red Chamber, also died of a cold.
The 109th time wrote: "Since then, the mother of Jia did not eat for two days, the chest is still knotting, feel dizzy, coughing, the spirit is still good. The doctor came to diagnose the pulse, said the age of the person stopped some diet, cold some wind-cold, slightly dissipate some of the dissipation on the good. Opened the prescription, Jia Zheng read, know is common medicine, ordering people to decoct good into service. In the future, Jia Zheng morning and evening to come in to ask for peace, a series of three days, do not see a slight reduction." This is so, within a few days died.
Because the ancients did not know the bacterial virus, once there is a large-scale infection, are called plague.
There were countless plagues in ancient China and in foreign countries, but mankind did not perish.
On the contrary, in the case of viral infections, for example, those with weaker immunity died after infection, and those with stronger immunity lived on tenaciously. Over time, the immunity of the offspring of these survivors is bound to increase.
It can be said that this is also nature a slow process of survival of the fittest, and later gradually have antibodies, not afraid of these diseases.
In those days, the white man first arrived in the Americas, bringing with him smallpox, cholera, influenza and the like.
The local Indians, who had never been infected with these diseases, had a very thick death rate. Sometimes a single cold killed half the population of an Indian village.
But over time, it's impossible for Indians today to say that one cold killed them, and that's the reasoning.
There may have been many outbreaks of viruses like New Crown in ancient times, but the human race would never have died out.
In fact, when it comes down to it, it's other viruses like smallpox virus that are lethal, and were absolute killers in ancient times, that New Crown is nothing.
And in ancient times, there were actually a lot of barriers to the spread of infectious diseases.
The vast majority of the inhabitants of ancient times were farmers. And farmers were self-sufficient, growing their own food and vegetables, and as for the necessities of life, going to the market a few times a year was enough.
Previously, many residents of mountainous areas, only once a year the horse gangs into the mountains to sell goods, which is also enough. Ordinary people, nothing more than to buy some salt, agricultural tools, clothes, shoes and hats and so on. Among them, except for salt, which is a consumable, the others can basically be used for a long time.
So, the ancient farmers basically do not casually mobile, generations live in their own village.
There are many country women who have never left their village in their lives.
There was very little mobility, which made it difficult for the virus to spread.
How can it be like today, nothing a ride on a high-speed train across half of China, a plane flight to foreign countries.
In addition, in fact, most of the cure of the new crown is also rely on their own immunity, outside things are auxiliary.
If your immunity can't hold up, the medical equipment is still going to kill you.
Moreover, at present, the United States has done a survey, the vast majority of deaths of patients with new crowns, are over 65 years old. Most of these people are debilitated, immunocompromised, and many have various diseases and even cancer themselves.
Not to mention the new crown, they even suffer from the common cold is also a certain risk.
And the ancient people due to long-term physical labor, although the medical level is low, but the immunity of young adults may not be significantly lower than today's people, or even stronger. And the new crown for young adults mortality rate is not high, the mortality rate of people aged 25 to 34 years old is only 0.6%. Keep in mind that the annual mortality rate for the common flu in the United States, too, is 0.14%.
The real danger is the ancient elderly, who are afraid of a high mortality rate when they get the disease. What makes people speechless is that there weren't really too many old people in ancient times. Have you heard of the ancient age? In ancient times, the 70-year-old old man is ancient rare, most of the old people live to the age of 50 or 60 years old died,In addition, the ancients for the plague also have their own method, is to drive to extinction.
During the Black Death in Europe, the entire region was often blocked, and no one was allowed to enter or leave, and then all the patients and the houses where the patients lived were burned, and some of the patients were not yet dead or burned. As for nomadic people, it is even more exaggerated, once encountered the bubonic plague and so on, infected people are often immediately buried alive to avoid affecting others.These tactics seem vicious, but they eliminated the source of infection at the source.
Of course, no one would dare do that today.
