Why viruses are becoming more and more harmful to humans

The vast majority of viruses are harmless to humans. The pathogenic viruses also have different kinds of viruses that cause disease and are harmful to the human body. Mild ones cause colds, severe ones cause chronic infectious diseases such as hepatitis, and of course some are more serious ones such as rabies virus, HIV, etc.

There is currently no effective method.

One, viruses

Second, the harm of the virus to peopleAfter reading this, you must also have a general understanding of the virus.

The essence is a non-cellular organism; After the virus enters the host cell, it uses the matter and energy in the cell to produce a new generation of viruses that disrupt normal cell reproduction.

Composed of a protein shell and internal genetic material, viruses that are harmful to the human body belong to animal viruses, which use the nutrition of living cells in the human body to replicate their own genetic material and thus reproduce offspring.

Viruses multiply and grow with the help of other cellular organisms.

Because the virus absorbs the nutrients of our body in order to reproduce and reproduce in us, the virus becomes more and more powerful, and when our body can no longer bear it, it will damage our health.

Viruses are essentially cell-free proteins. By binding to the body's cells, the virus destroys the normal functioning of the body's cells.

Harmful side: Sickens people and other living things and endangers their health. For example: smallpox, viral hepatitis, poliomyelitis, influenza in humans, foot-and-mouth disease and rabies in animals, as well as tobacco mosaic disease and potato degeneration in plants.

On the plus side:

1. Bacteriophages can be used as specific drugs for the prevention and treatment of certain diseases, such as applying Bacillus aeruginosa phage dilution to the affected area in burn patients.

2. In cell engineering, some viruses can be used as melting aids for cell fusion, such as Sendai virus.

3. In genetic engineering, viruses can be used as carriers of target genes to be spliced on the chromosomes of target cells.

4. Viruses added to a specific bacterial medium can be impurified.

5. Viruses can be used as carriers for precision-guided drugs.

6. Viruses can be used as special insecticides.

7. Viruses also play a key role in the material cycle and energy exchange in the biosphere Viral vaccines are good for human beings to protect against viruses - promoting the evolution of human beings, and many of human genes are derived from viruses.

Viruses and humans have a symbiotic relationship, and 8% of the genes in the human body belong to viral genes.

The virus and human beings will coexist for a long time, the advantage is that the existence of the virus can enhance the body's resistance, and the disadvantage is that it will cause harm to the human body.

Humans have viruses because they have been on Earth for a long time, even before the emergence of humans. Viruses are very tiny organisms that do not possess a complete cellular structure, only a genome and shell. Viruses cannot replicate on their own, but can infect other cells, inject their own DNA or RNA into the host cell, use the host cell's biosynthetic mechanism to copy their own genetic material, and cause the host cell to produce damage, so as to continue to spread its genome.

Some viruses only infect specific species of animals, unlike the plague virus, which only infects mice, while humans cannot infect them. But other viruses, such as influenza and coronavirus, can cross species barriers to infect different animal species, including humans. Viruses mutate as they multiply, which can lead to their ability to cross species barriers to infect new hosts.

In addition, humans live in the same environment as other animals, so the risk of virus transmission is also relatively high. For example, certain agricultural activities, poultry markets, or animal trading markets may bring many different species of animals together, which can help the virus infect across species.

Viruses are naturally occurring organisms that are part of the life-threatening systems that air above the Earth. Although they may pose serious health and economic risks to humans, their presence is also a counterbalance to natural systems. The measures taken include strengthening hygiene and preventive measures to reduce the spread of the virus and the harm to humans.

Human beings have viruses because viruses are microorganisms that exist for hundreds of millions of years, and they exist in various organisms and environments in nature.

Viruses exist in humans not because humans have any problems with their own sensitivities, but because viruses themselves are widespread in nature. Hope.

The struggle between humans and viruses has begun since the time of Australopithecus, and in the struggle of millions of years, the ** of human beings against viruses is developing, and viruses are also evolving, choosing the most suitable way to survive.

Many viruses have abandoned the confrontation with the human immune system, signed an armistice, and since then have settled in the human body, and the number of these viruses is not rare, reaching more than 380 trillion.

Many people may not believe it, but every surface inside and outside our body is covered in microbes--- bacteria, viruses, fungi, and many other microscopic life ---forms.

These viruses aren't the dangerous viruses you hear about often, such as those that cause the flu or the common cold, or the more sinister viruses like Ebola or dengue sylvestris.

Wen Jiantan is an inevitable product of natural co-evolution, because the excessive lethality rate will sometimes make Hu cut off the source of infection, so that he can not continue to spread, so the choice of maximizing benefits is better than "forever", they choose to survive in the human body, and naturally become a community of destiny with human beings.
