What is the only virus that has been eliminated in thousands of years of human history?

Smallpox virus is a very deadly disease in ancient times, this virus first appeared in the Eastern Han Dynasty Guangwu Emperor Jianwu period, because people have never seen such a disease at that time, so there is no way to start such a disease, and this is the earliest smallpox, the earliest example of smallpox virus in the world appeared in ancient Egypt more than 1100 years BC, and the people of ancient Egypt through continuous human activities, the smallpox virus also slowly spread, due to the low level of medical care at that time, So the smallpox virus has become a nightmare in the hearts of many people. <>

Later, with the smallpox virus continued to spread, when it was introduced into our country, it also began to pose a huge threat to our country, as a virulent infectious disease, smallpox is undoubtedly very terrible, because people do not know the smallpox, and do not know how, so in the past thousand years, smallpox has killed a lot of people, and people at that time in order to survive, also thought of various ways to eliminate smallpox.

In ancient times, people found that once people were cured of smallpox, they would no longer suffer from smallpox for life, so the medical technology at that time would use the tip of a needle to dip the pus from smallpox patients and pierce them into the ** of people who did not have smallpox, and this idea is somewhat similar to our current vaccination. <>

At that time, it was not easy for medical staff to think of such a way to prevent smallpox, and this phenomenon continued until 1789, when the English village doctor invented the vaccinia inoculation method, which greatly reduced the mortality rate of vaccinia. <>

It was through this doctor's method that we humans officially defeated the smallpox virus from thousands of years to 1789, which is the only virus that we have ever been able to eradicate in history, and from the birth of smallpox to people, to the presentSmallpox has been battling smallpox for at least 3,000 years and has finally been contained, so I believe that in the future, we will continue to improve our medical care and one day we will defeat these viruses.

Because viruses are tenacious and some viruses are smart, it is not easy for humans to eradicate them.

Because the smallpox virus can be eliminated with the help of current medical conditions, and there is no source of infection, the survival rate is very low.

Because the spread effect of this virus is not particularly high, and it is relatively easy to crack, and the corresponding immune virus has also been quickly studied, and there are corresponding vaccinations.

Because the smallpox virus has a fatal flaw, it is a double-stranded DNA virus, so it does not mutate easily. Coupled with a certain amount of luck, humanity was lucky enough to defeat the smallpox virus. The smallpox virus is very powerful, directly harvesting the lives of hundreds of millions of people.

If it weren't for this fatal flaw, it would not have been easy to defeat smallpox once and for all.

The first infectious disease to be eradicated by humans was smallpox.

Smallpox is one of the oldest and deadliest infectious diseases. At the end of the 18th century, the British immunologist Jeanne invented "cowpox" to prevent smallpox, and humans began to widely vaccinate against smallpox. In 1980, smallpox was declared eradicated.

The smallpox virus mainly invades the human body through the mucous membranes of the respiratory tract and is transmitted through droplet inhalation or direct contact. The two types of virus strains with different virulence of smallpox virus are the most virulent to cause normal smallpox, that is, typical smallpox; The weak cause mild smallpox, i.e., smallpox-like.

As of February 8, 2021, **smallpox, there is no effective method, and it is still mainly supported**. Vaccinia inoculation and vaccinia immune globulin may have some post-exposure prophylaxis. **Antiviral agents for smallpox are still being studied.

The antiviral drug cidofovir has been shown to be effective in both in vitro and in vivo studies in experimental animals, but it must be used before or after viral infection. Scientists at the U.S. Army's Medical Research Center for Infectious Diseases, who work at the US Centers for Disease Control and Prevention, are conducting in-depth research on this drug and other compounds in animal models.

The first deadly infectious disease to be eradicated in the history of mankind was smallpox.

When it comes to "smallpox", many people feel very unfamiliar. It is true that the virus that was completely eradicated in the world on May 8, 1980 is a thing of the past, and if we have heard of it, it is probably in literature and television movies. But in the past few thousand years, it has led to the collapse of the kingdoms of continental Europe, the tragic death of kings, and even the flow of refugees during the Ming and Qing dynasties in China.

The return time of Shenzhou 12 is at about 13:30 on September 17, 2021, and the landing location is at Dongfeng Land and Chan Land Field. After the thrust reverser engine of the return capsule of the Shenzhou 12 manned spacecraft was successfully ignited, it landed safely in the predetermined area of the Dongfeng landing site, which was the first time that the Shenzhou spacecraft landed at the Dongfeng landing site.

Shenzhou-12 return time and landing place.

The Dongfeng landing field is located in the depths of the Badain Jaran Desert in the western part of the Inner Mongolia Autonomous Region, where the land is vast and sparsely populated, and the topography is mainly desert, mountain, grass lake and Gobi.

At 9:22 on June 17, 2021, the carrier rocket of the Shenzhou-12 manned spacecraft was successfully launched at the Jiuquan Satellite Launch Center.

The astronauts who carried out the mission of the Shenzhou-12 manned spacecraft were Nie Haisheng, Liu Boming, and Tang Hongbo, of which Nie Haisheng was the third time to go to space, and Liu Boming was the second time to go to space. Content.

Human beings became acquainted with the virus at the end of the 18th century, but it was in 1939 that scientists observed the tobacco mosaic virus through a microscope.

The appearance of this microorganism is what humans can understand!

After another hundred years of precipitation, human understanding of the virus has gone from being ignorant at the beginning to having a deeper understanding now. To put it simply, viruses are a mass of proteins packed with genetic material that are quite small in size and distributed all over the world.

Although small, the harm is great, and almost everything related to natural death, is related to them. For example, the new crown epidemic that broke out at the end of 2019.

is caused by the new coronavirus.

caused. Going back in time, the bubonic plague in Europe, the century-old smallpox, and the dreaded cholera.

It's all caused by viruses.

But viruses are different from all living things we know, they don't have the organelles that a normal cell should have.

For example, mitochondria.

chloroplasts, etc. A virus with only genetic material and an outer shell does not look like a living organism. (Definition of life:.)

In the process of the development and change of the universe, there is a certain kind of phenomenon that naturally appears in the process of self-growth, reproduction, feeling, consciousness, will, evolution, interaction, and other rich possibilities. ）

Through the definition of life, we can see that viruses do not fully meet the conditions. It only produces a little bit of life in the host, so for thousands of years, people have not been able to answer the question of "whether the virus is alive or not". We can only tentatively set it to:

A virus is a special existence between non-life and life.

Although the virus is in an inactive mode outside the host, it can neither replicate itself, nor grow in sight, or even be conscious. But when it reaches the human body, it undergoes a certain biochemical reaction, using the host cell to replicate itself, and from this point of view, we consider it to be life. Viruses that float outside the host do not belong to the category of life.

Viruses were discovered at the end of the 18th century, and viruses are also alive, can cause serious harm to the body, and can bring great harm.

It was around the end of the 18th century that scientists saw viruses through microscopes. Viruses are single-celled organisms and are also living beings.

Viruses have been with people since the beginning of human society, but different viruses have different effects on the human body. Humans are also becoming more and more resistant to viruses.

If all the viruses are gone, then humanity will be completely wiped out. Viruses are now integrated into the Earth's ecosystems, sustaining life on Earth through high-speed photosynthesis.

Viruses always seem to wreak havoc on society and cause human suffering. If you could make all the viruses go away, most people would probably make this choice. But it would be a fatal mistake, in fact, more lethal than any virus.

The vast majority of viruses are not pathogenic to humans, and many play an integral role in supporting ecosystems. Others maintain the health of individual organisms – everything from fungi and plants to insects and humans.

Without the virus, life and the planet, as we know it, would cease to exist. Even if we wanted to, we might not be able to wipe out every virus on the planet. But by imagining what the world would be like without viruses, we can better understand not only how important they are to our survival, but how much we need to know.

Bacteriophages are the primary regulators of bacterial populations in the oceans and possibly in every other ecosystem on Earth. If the virus disappears suddenly, some bacterial populations may **. Other populations may lose their competitiveness and fail to grow altogether.

These microorganisms produce about half of the oxygen on Earth, a process involving viruses.

Every day, these viruses kill about 20 percent of all marine microbes and about 50 percent of all marine bacteria. By killing microorganisms, the virus ensures that oxygen-producing plankton have enough nutrients to carry out high-rate photosynthesis and ultimately sustain most life on Earth.

Researchers who study pests have also found that viruses are essential for controlling species populations. This process is known as "killing the winner", which is also common in many other species, including ourselves, and has been proven by the pandemic. If the virus disappears suddenly, competing species may thrive, harming other species.

Some organisms also rely on viruses to survive or give them an edge in a competitive world. Infection with certain benign viruses can even help ward off certain pathogens in humans. It can be seen that although some viruses have caused great harm to human beings, viruses are indeed an indispensable part of the existing earth's ecological system.

In general, some viruses can kill people, and some viruses can also help humans and sustain life. The virus cannot be completely eliminated, and if it is all eliminated, then humanity will die out very quickly.

If all the viruses in the world were gone, humanity would soon be extinct. Viruses play a key role in the global carbon cycle and are part of nature, without which life cannot evolve.

If all the viruses in the world disappear, then it is likely that human beings will not be able to survive healthily, but will be more likely to get sick, and the consequences will be unimaginable.

Humanity may have eternal life. But not all viruses will disappear, and even if the existing viruses disappear, there will be new ones in the future.

There are two thorough divisions here, one is to find a solution to reduce disease morbidity and mortality; The other is that the virus has completely disappeared from the world.

First of all, let's talk about the solutions that have been found, what are the viruses that can be **?

The first is rabies, once rabies is onset, there is no way, the patient is afraid of water and wind, and the death is miserable, but now under science and technology, people have a vaccine and immunoglobulin to prevent rabies, which can almost control the occurrence of rabies, and the incidence of rabies in the world is very low at this stage.

The second is the influenza virus, although the spring and winter of each year are still the peak period of influenza, but the influenza usually has a certain degree of self-limiting, and the body can regulate itself for a certain period of time. And you can take drugs such as oseltamivir for prevention, and within 48 hours, you can also block the virus, which almost minimizes the impact of influenza on humans.

Let's talk about the virus that was completely eradicated - smallpox, when smallpox was epidemic, the incidence was high, the fatality rate was high, and the recovery effect was very poor, since the vaccinia vaccine was inoculated worldwide, and the smallpox virus itself had higher requirements for the host, and finally human beings eliminated smallpox, which is also the only virus in human history that has been completely defeated theoretically.

In fact, many viruses are not incurable at this stage, such as hepatitis B virus can be effectively blocked, AIDS can prolong the length of life, etc., although they cannot be avoided, but they can effectively ** or prolong the course of the disease and improve the recovery effect. Viruses are also a kind of nature, and it is almost impossible to defeat all viruses, and learning to get along with them, doing a good job of prevention, and reducing the harm of viruses to human beings is what we should gradually do at this stage.

It may not be possible to completely overcome it, but the smallpox that we all know will not get by now, because of the effect of the vaccine, and now everyone has human antibodies, and it will not appear.
