    The reason why alcohol can be sterilized is because it has a bactericidal effect. The main components contained in alcohol are ethanol and isopropyl alcohol, both of which have a strong bactericidal effect. When the alcohol solution comes into contact with microorganisms such as bacteria, fungi or viruses, it will quickly penetrate into the cell membrane, destroy the integrity of the cell membrane, cause the cell to lose water, deform, and cause cell death.

    In addition, alcohol can also denature and coagulate proteins and acid nucleic acids in cells, thereby destroying the genetic material of microorganisms, preventing their growth and reproduction.

    It should be noted that alcohol disinfection is only suitable for surface disinfection, and it is difficult to disinfect other microorganisms such as viruses, bacteria and fungi at a deep level. Also, alcohol does not kill spores-containing microorganisms because the cyst shells of the spores are highly resistant and require other disinfection methods to sterilize.

    Therefore, when using alcohol disinfection, it is recommended to read the instructions of the alcohol disinfectant carefully and pay attention to the method of use and dosage to ensure effective and safe disinfection.

    Alcohol can kill viruses because it can bathe and decompose the virus's lipid mantle q,envelope, so it must be a virus with a mantle like the coronavirus for alcohol to work effectively. The method of using alcohol for disinfection and sterilization is mostly to use 75% alcohol (the effect is better than 95%), wipe the ** surface or the surface of the object to achieve the disinfection effect. In addition to this, alcohol can also deactivate proteins, dlenaturation, so it can also inactivate the virus.

    The reason why it is not so simple to deal with viruses is that viruses do not have a cellular structure and are made up of DNA or RNA

    It is composed of proteins, which cannot grow and replicate independently when they exist alone, but they are not destroyed, but once the virus finds a host to parasitize, it can use the host's cell system to replicate and cause infection. To put it simply, when there is no host, a virus is nothing, and it can barely be said to be a piece of information;

    However, once it is parasitic on an organism, it will infect other living organisms vigorously. Viruses are not unkillable, but they are not as simple as bacteria, and they can be solved with alcohol. There are basically two ways to kill the virus, one is to heat it to a specific temperature and continue it for a period of time to denature and lose the activity of DNA and RNA.

    The second is to disinfect with hypochlorous acid water Q and bleach, which can destroy the outer shell of virus proteins.

Alcohol is volatile, can take away part of the surface bacteria, and 70%-75% of the alcohol is used for sterilization and disinfection, and the anti-virus effect is very good, but alcohol can only destroy part of the bacteria, high temperature disinfection is generally the use of high temperature to inactivate some bacteria, so as to achieve disinfection, but there is no real sense of 100% or complete disinfection.

It is best to disinfect with alcohol, if there is no alcohol around for a while, you can also use alcohol wipes for emergency, but you must go to the hospital as soon as possible to deal with it, if it is just a small wound, then you can treat it with red syrup, this only refers to a small wound, and it is not a wound caused by rusted iron, otherwise you have to go to the hospital for tetanus injection.
