Scientists warn of 850,000 unknown viruses that could infect humans. Is the pandemic coming?

The only correct answer to this question is: "Human society will inevitably be attacked by other unknown viruses in the future". After the new coronavirus, more unknown viruses will wait for opportunities to invade the human body (or animals or plants), because the virus can only have life functions and reproductive ability when it finds a host.

Of course, not all viruses target humans, and there is no need for humans to protect against all viruses.

I am happy to come with you to ** the concept of "virus", in the eyes of many people, when it comes to "virus", they are disgusted and full of fear, no wonder, it is "disease" and "poison", for the human body: "virus" is like a demon. Alack!

"Virus" is actually just a general term for a life-like species, and there are thousands of viruses on the earth. However, in fact, some viruses are beneficial to humans, most viruses are neutral, neither beneficial nor harmless to us, and only about 10% of viruses are harmful to humans.

What's more: a "virus" is something similar to a protein, it has no cells, it doesn't move, and when it can't find a host, it's like a grain of sand, showing no signs of life. When the virus has the opportunity to attach to the body surface of a human or animal or plant, it may be killed by the substances secreted by humans or animals or plants before it reacts, even if it can enter the oral and nasal cavities of humans or animals, it is also difficult to escape the doom (the oral mucosa and nasal mucosa will also annihilate the virus).

The body's immunity has layers of defense, and the virus will not succeed easily. If the human body is infected with the virus, either there are too many viruses that break through the layers of defenses of the human body (so washing hands frequently, wearing masks, and keeping a certain distance between people and animals are very effective in preventing the virus), or our own immunity is too low at the moment (so it is important to improve immunity).

Having said that, humans and viruses share the same earth, which is the arrangement of nature, and it is impossible for humans to kill all viruses. We have been ignorantly inventing a lot of antiviral drugs, greedily spraying our own camp with all kinds of venom, always trying to create a seemingly safe environment that is completely free of viruses. The outbreak of the new crown may have been caused by this foolish move.

Now the world is pinning its hopes on "vaccines" to stop the epidemic, but as everyone knows, it is difficult to keep up with the speed of research on "vaccines" to keep up with the speed of "virus" mutation, even if the "virus" does not mutate, is the use of "vaccines" a blessing or a curse for mankind? The antibiotic dose is still fresh in our minds, and the dose of antibiotics is increasing from generation to generation, and mankind has realized that when "superbugs" appear, human beings may be "dying". Won't antiviral drugs and some so-called "vaccines" follow in the footsteps of "antibiotics" and become catalysts for "super viruses"?

The only way for human beings to evolve their "immune system" is to do so!

Only by caring for all living beings on the earth, even if it is a small ant, even if it is a grass or a tree, human beings can only take care of them, so that we are qualified to talk about building a beautiful home.

In an authoritative report published a few days ago, biodiversity and pandemic experts warn that as we continue to fight the coronavirus, we must also look ahead to prevent the world from entering a "pandemic era" in the future, where zoonotic diseases that spread more frequently and more rapidly. If we don't take steps to end risk drivers such as deforestation, intensive livestock farming and wildlife**, even worse crises will come.

1. More than 500,000 epidemic viruses threaten humans.

A few days ago, the IPBES workshop led by the United Nations Biodiversity and Ecosystem Services Agency released a new report, reporting that there may still be 540,000 to 850,000 unknown viruses in nature that could infect humans and cause more deadli, expensive and frequent pandemics in the future. The report describes this future scenario as the "pandemic era" and makes it clear that the main risk factors must be prioritized, as the cost of prevention is 100 times lower than the economic impact of the current pandemic.

The report of the IPBES Symposium brings together the views of 22 of the world's top experts and more than 600 experts in different fields of epidemiology, zoology, public health, wildlife health and public policy. As a result, this report is recognized as one of the most scientifically robust investigations demonstrating the link between pandemic risk and nature.

2. What caused the pandemic?

Dr. Peter Daszak, chair of the IPBES workshop and president of the Ecohealth Alliance, said: "There is no mystery about the causes of the coronavirus pandemic or any modern pandemic. It is human activities that drive climate change and biodiversity loss, but also environmental change, which drives the risk of pandemics.

Specifically, the way we use land, the expansion and intensification of agriculture, and unsustainable **, production and consumption, destroy nature and increase the risk of contact between wildlife, livestock, pathogens and people, ultimately leading to the outbreak of the pandemic. ”

3. How should we respond?

Specific response measures recommended by the experts include: the establishment of an inter-pandemic prevention committee to address high-risk areas and coordinate a global monitoring framework; Incorporate the concept and approach of "One Health" into the strategies of each national sector; and comprehensively strengthen the law enforcement of illegal wildlife activities. The report also notes that it is critical that we make a major shift in reducing livestock production.

Because traditional livestock production is a key factor in the pandemic. This has been confirmed by an earlier report by the United Nations. And intensive livestock farming can lead to unsustainable land use, deforestation, and large amounts of carbon emissions.

Experts say that in order to incentivize and promote the shift to intensive animal husbandry, a tax on meat consumption could be considered.

"We could have avoided the pandemic era, but that required a greater focus on prevention beyond the response," Dr Daszak said. We are still relying on vaccines and ** to control pandemics, largely ignoring early prevention, even as our ability to prevent pandemics is growing. ”

The virus is constantly spreading, and the natural tendency to mutate is to become less and less virulent and mortal.

It will gradually decrease, but the contagiousness will gradually increase.

In fact, it is not difficult to understand that although the virus is small, it has the same purpose as the existence of organisms in nature, which is to perpetuate their genes. If the host dies too quickly, it will also cause the virus in its body to die; If the host symptoms are too severe, they are quarantined**.

Whether the host dies or the symptoms become too severe, neither outcome is conducive to the spread of the virus. Therefore, the trend of virus mutation will develop in the direction of low case fatality rate and mild symptoms. In general, the virulence is decreasing and the infectivity is increasing.

The specific manifestation is asymptomatic infection.

More and more. <>

Maybe in the future, the coronavirus.

It could be like the flu.

It will persist in human society for a long time, but the lethality may become as low as the flu.

However, at this stage, it is still the early stage of the spread of the new coronavirus, and the case fatality rate is still very high. Moreover, it cannot be ruled out that after infection, the virus will produce an "atavistic phenomenon" and mutate back to high virulence, so everyone cannot report that there is a fluke mentality, and strengthening self-protection is still the top priority.

Asymptomatic infection, is it a new term that is newly discovered and heard, in fact, the noun is not new, the virus has long existed, the virus evolution and mutation are cunning, it is very hidden, so that human beings can not be careful, what a dangerous and terrible virus, people mention this virus, people feel numb. The virus is not easy to detect and overcome, and the person infected with the virus will develop an antibody that has no feelings for himself, but he will infect more people.

If asymptomatic infections remain high and gradually rise, it will bring catastrophic consequences to human beings, symptomatic viruses are clear and clear, people often say, open guns are easy to dodge and dark arrows are difficult to prevent, asymptomatic and will infect people of the virus, this is the most terrible and dangerous virus, this is the silent bomb buried around us, the bomb is not loud and powerful, its lethality and destructive power is much higher than the time bomb, screening and inventory of this asymptomatic infection, to rely on the efforts of virology experts, relying on the joint efforts of the whole people and the whole society.

Let's look forward to the early development of a vaccine to save the world.

Yes, indeed, because the weather is very hot these days, the virus is very afraid of high temperatures, and as soon as the weather is hot, the virus will slowly disappear.

Yes. The virus is no longer as virulent as it used to be, and people infected with the virus no longer have as many symptoms.

A leading infectious disease expert has issued a dire warning about the novel coronavirus. The coronavirus has infected 4.2 million people worldwide and killed 290,390.

Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota, said the onset of COVID-19 accounts for only a small fraction of illness and death in places like New York City, Los Angeles and Seattle.

"The damn virus is going to go on until it can infect everyone," Osterholm said at a meeting with USA Today's committee on Monday. " It will certainly not slow down until it reaches a population ratio of 60 to 70", a number that will generate herd immunity and stop the spread of the virus.

The Spanish flu of 1918 was the most severe pandemic in recent history and caused several waves around the world.

If new cases of COVID-19 begin to subside this summer, it could be a sign that the new coronavirus is following a seasonal pattern similar to the flu, scientists say.

"It's really the biggest peak we're going to get into," he said. He explained:

In terms of the pain, suffering, death, and economic disruption we have experienced, between 5 and 20 people have been infected. ......There is still a long way to go to reach 60 to 70 people. ”

Osterholm also told the newspaper that only an effective vaccine can slow down the spread of the virus before enough people become infected and develop some level of immunity.

But even if the vaccine works, it is not yet known whether it will be durable enough to provide long-term protection against SARS CoV-2, also known as COVID-19, Osterholm said.

As we all know, the ocean is vast, and the unknown creatures in the ocean are incalculable. Viruses are parasitic, which means that every organism may carry the virus. Animals have already coexisted with the virus, so they may not react to the virus.

Animals carry all kinds of viruses, including devastating viruses, so indiscriminate consumption of wild meat can easily cause epidemics and cause thousands of infections and even deaths.

There are too many types of viruses to count, and there are many unknowns. Viruses also evolve, and the speed of evolution is so fast that humans don't have time to count them, and viruses evolve into other viruses, and scientists have found that there are many ancient viruses hidden under the Antarctic ice.

Scientists have not given a specific answer to the number of viruses on Earth. There is still a lot that is unknown.

The formation of tens of thousands of years has caused the Antarctic and Arctic ice to be very thick, and it is estimated that many animals and plants are frozen in it, and most of the viruses exist on animals and plants, so there must be a lot of unknowns. Just over two decades ago, it was inferred that there were more than 1 million 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.
