Viruses are so harmful, so why do scientists keep those terrible viruses?

Because after retaining, the virus can be cracked according to observation or some experiments, or it can be used to develop drugs that are more beneficial to people, which is also a contribution to medicine.

Reserve for the sake of study, to study and work out the way of salvation, so that when it is a last resort. Although the virus is terrifying, scientists can protect us through continuous research and testing, which is naturally inseparable from "samples". We should trust scientists and their research.

Scientists keep these harmful viruses not so that they are harmful to the world, but to keep them as specimens, and if there are similar situations in the future, they can be cured by diagnosing the virus.

Because some viruses can restrain the infection of others, and part of the reason is that saving one virus can know the ** of this virus, and it can also better support the generation of another virus.

There are two sides to everything.

Because for scientists, it is necessary to analyze the structure and transmission route of the virus in order to develop corresponding vaccines and drugs.

Since the virus is already considered to be harmful, it is definitely necessary to research to better control or prevent or prevent the occurrence of the virus.

This is the evolution of cells over millions of years, and through the evolution of special viruses. There are a lot of viruses, like the flu virus, that can be modified according to people's designs, but it can't be modified at will. It is possible that some of the modifications we designed cannot be recombined into viable viral particles.

Yes, it is a tiny substance that has to be parasitic in living cells, which may be caused by unhealthy eating habits, and the virus parasitizes in the hard disk of the medium, forming a source of infection, and then activating the virus and triggering the conditions of the virus. The virus spreads very quickly.

This is the evolution of cells over millions of years, through which special viruses have been formed, and their own structures have been produced, which scientists should not be able to make.

Viruses exist in some genetically modified forms in nature, and scientists can currently create viruses.

Ivanovsky was the first person in the world to discover the virus and is hailed as the "father of virology".

In the 19th century, Ivanovsky (1864-1920) speculated that the disease was caused by bacteria when studying the disease of tobacco mosaic. He squeezed the juice out of tobacco with mosaic disease, filtered it with a filter that could filter out bacteria, and then used the filtered juice to infect normal tobacco leaves, and found that normal tobacco leaves could still be diseased. This suggests that tobacco mosaic disease is caused by a pathogen smaller than bacteria, which he called "filtering virus".

Later, scientists Leffler (1852-1915) and Frozch (when studying foot-and-mouth disease in animals) proved that foot-and-mouth disease was also caused by "filtering viruses". In other words, Ivanovsky was the first person in the world to discover the virus and was hailed as the "father of virology" by later generations.

The scientist who first discovered the virus was: Ivanovsky.

The first scientist to come up with the concept of a virus was Bejechlin of the Netherlands.

Summary. Observe the protein receptors on the surface structure of the virus, and the more receptors there are, the easier it is for cells to bind and then infect.

How did scientists find the disease-causing virus in hundreds of millions of viruses in the human body? So many viruses are scientists trying out one by one?

Hello, I have seen your question, and I am sorting out the relevant information for you, and I will reply to you immediately

Hello, no. Harmful viruses can be isolated from pathological tissues.

For example, nasal discharge and the like.

Uh-huh, but there are tens of thousands of viruses and bacteria in the nasal discharge, do you have to try them one by one?

No, the structural characteristics of the virus are used to analyze whether it is infectious, and transmissibility is usually an important way for the virus to develop its pathogenesis.

Most of the viruses in the human body are in the gut, right? Very little virus in the blood?

Yes, there are white blood cells in the blood, which can kill the virus.

An international team of researchers in Austria has discovered a previously unknown virus in human body fluid samples. Researchers are looking for viruses that infect bacteria, known as bacteriophages, with a focus on those that attack E. coli found in the human gut. The research team identified a total of 43 bacteriophages in human body fluid samples, particularly blood samples.

There is also a virus in the blood.

This is something special.

Analyzing whether the virus is infectious through the structural characteristics of the virus, transmissibility is usually an important way for the virus to pathocate.

I don't know what virus it is, how to analyze the structural characteristics, and whether it is still tried out one by one.

Observe the protein receptors on the surface structure of the virus, and the more receptors there are, the easier it is for cells to bind and then infect.

Thank you, you're so nice.

Uh-huh, you're welcome.

It's because you say that a virus has no life, and it can be transmitted and can be regenerated, and you say it has life, but it really doesn't have any life characteristics, and it's not even a cell.

Because viruses do not have the characteristics of life, but they can replicate and mutate on their own, scientists say so.

Because the virus will parasitize in the human body, and then spread and spread; But when people die, so does the virus.

Problem description: Are all viruses thought to be made? Why do these people go out and create viruses?

Analysis: There are many different reasons why computer viruses are created. For example:

The virus is deliberately created by employees to take revenge on the company and express their dissatisfaction; Some are just used to celebrate certain festivals; There are even some created by religious and political fanatics in order to make their voices heard through these channels. Some programmers create viruses to show their abilities or challenge themselves or others, and they just want to see what the consequences of the virus will be or see if someone can get rid of it, but they are misusing their abilities.

In fact, many "viruses" are just bugs in the program. When a program crypto silversmith designs a new program, many times they don't notice the small problems or bugs in it. It is because of these small problems or bugs (bridge bugs) that some unnecessary finger sensitive lead orders and effects have been caused.

Therefore, a good programmer should thoroughly check and test the program before it is made public. In fact, most "bug" viruses are not destructive, so it is correct that these bug viruses should be defined as "bugs" rather than "viruses".

How does it attack a computer?

When a packet is sent to a port, the port is used and replied with a receipt packet, which is sent to another server, which sends back a receipt packet and forms a loop.

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.
