In fact, viruses exist longer than humans. Viruses are the largest form of "life" on earth. There is no harsh environment on earth that can completely kill the virus. For example, there are viruses under the ice in Antarctica. We humans actually live in an environment surrounded by viruses.

Having a virus is not a bad thing. The existence of virus has promoted the continuous improvement of human immune system and played a positive role in the process of human evolution. Even in healthy people, there are a considerable number of viruses and bacteria, but because of the existence of the human immune system, they can't afford the storm.

However, due to the illegal predation of wild animals by humans, many viruses that originally existed only in animals began to spread from their natural hosts to humans! For example, novel coronavirus this time.

Once novel coronavirus enters human cells, there is no specific medicine at present. We can only try to inhibit its replication with broad-spectrum antiviral drugs, and then eliminate it with the help of the human immune system. The effectiveness of drugs such as Redixivir and Abidol has been continuously collected, but it remains to be seen.

Viruses entering human cells are not easy to be killed, but viruses leaving host cells are very fragile. For example, novel coronavirus is sensitive to ultraviolet rays, heat, 75% alcohol and chlorine-containing disinfectants. As long as you are exposed to the above disinfection measures, the virus will be inactivated soon.

Because novel coronavirus can be transmitted through respiratory droplets and contact, fecal transmission cannot be ruled out, so we spray chlorine-containing disinfectant to kill novel coronavirus who left the human body and reduce the possibility of transmission, which is very important for epidemic control!

I'm glad to answer your question. Humans can't kill viruses, which means they can't kill virus infections. In other words, the virus in the infected person cannot be killed, which depends on the characteristics of the virus. Viruses consist of basic genetic material nucleic acid (DNA or RNA) and outer shell. It has no cell structure and cannot survive independently. It replicates by infecting biological cells and parasitizing them. Once out of the organism, it is difficult to survive in the air, so the virus can still be killed under certain external conditions. Different viruses have different living conditions and time in the outside world. For example, when the temperature exceeds 56 degrees Celsius, novel coronavirus can be killed within 30 minutes. Or 75% medical alcohol for 3 minutes.

Hello, I'm glad to answer your question.

First of all, human beings have existed on the earth for 2 million years, and intelligent humans have existed for 200,000 years. Virus, a creature, has been produced since the early days of the earth's birth and has a history of 3 billion years. It is more adapted to this planet than humans.

Secondly, this problem is better understood in another way. There are mosquitoes every summer. Why mosquito-repellent incense? Because it wants to bite people, it is necessary to extinguish mosquito-repellent incense and invade human space.

Viruses and bacteria are everywhere. Spraying disinfectant every day is to kill the free virus in this area, thus playing a preventive role.

Novel coronavirus is afraid of high temperature and alcohol. There are two battlefields to fight it, internal and external. The way to kill him is to isolate the virus in the human body, so that the population it produces will not spread out, kill the virus in the body through drug treatment, and kill the virus in vitro by spraying chemicals. This is why Wuhan is closed and the people of the whole country are isolated at home.

We can't completely destroy it, but we can let it leave the living space of human beings.

Wild animals contain a variety of deadly viruses, so refuse game and start from the side.

The virus will definitely be solved. It's only a matter of time. For our effective self-protection measures, we should protect ourselves, care about our families and cherish the people around us.

Immortality means that there is no way to kill the enemy in the body. Kill one thousand, lose eight hundred, and it's easy outside. Summarize four words: the boat is tired.

Disinfectant can really kill the virus, but now the virus mutates faster and faster, so this virus is killed, and when another mutated virus comes out, it doesn't work.

High-concentration alcohol can kill viruses around itself that have not yet entered the body, which is very good. A virus is a very primitive creature. Many genes in the human body are presumed to be left by viruses. Viruses are difficult to kill in the body, but they are really fragile in the surrounding environment. Alcohol at 75 degrees can completely kill viruses in the air, so that they do not enter the human body and do harm to human beings.

Be able to comfort yourself

The weather is fine, prepare for the bad weather.

All kinds of drugs should be removed from the syndrome.
