Why is there no specific medicine to deal with the virus?

This question must be a lot of people's doubts!

It is said that disinfection and sterilization used to make sense, but now it may have to be changed! The invasion and pathogenicity of bacteria and viruses are very complicated. This paper briefly summarizes some of the most relevant issues related to homicide for your reference:

From the analysis of boarding relationship: bacteria, as independent microbial individuals, can generally reproduce themselves outside the cell, unlike viruses stored in the cell. Without cells as hosts, viruses cannot survive. In addition, the virus can integrate its own genes into the host cell and rely on the metabolic system of the host cell for proliferation and replication. As a result, the replicated virus broke away from the cell and the human cell died. So it is not easy to remove the virus. This is also the main reason why the virus is difficult to remove.

The virus is deeply hidden in cells and hardly touches body fluids, so drugs are generally out of reach. Even if you can, you will contact cells first and kill normal cells. On the one hand, killing may lead to organ failure, on the other hand, the remaining live virus will continue to invade other normal cells.

Part of it is stored in the human body, waiting for the opportunity. When the human immune system is weak, they will come out to exercise, and people are prone to get sick at this time.

From the analysis of structural characteristics: 1, the outermost layer of bacteria has a cell wall. For example, penicillin destroys the structure of peptidoglycan on cell wall, affects the formation of cell wall and plays a bactericidal role. The surface of bacterial membrane mostly contains capsular polysaccharide, lipid and so on, although it shows the ability to attack target cells. But it is also easy to become an attack point for drugs. If these lipids and polysaccharides are destroyed, it will lead to the death of bacteria.

3. The virus has no cell wall and no cell membrane, which structurally determines that it cannot kill the virus like killing bacteria. Therefore, the virus can only be controlled by suppression to prevent replication and spread. But it has been integrated into human genes, and it is difficult to completely eliminate it. So as long as people are alive, they may recur one day.

Although Shuguang said it was disinfection and sterilization. But the new drug developed now has made people see the dawn! Especially in recent years, the biggest breakthrough, the successful development of new anti-hepatitis C drugs, has made hepatitis C patients have 80~90% cure possibility. This greatly enhances the confidence of patients in treatment and the research and development motivation of researchers! Also let cure hepatitis B and AIDS not far away!
