How on earth is AIDS infected? Under which circumstances are not easy to be infected with AIDS

As a global epidemic, AIDS is mainly caused by virus infection due to the deficiency of human immune system. Because AIDS is very harmful to the public, it has become a social public security and health problem that people pay close attention to. At the same time, the incubation period of AIDS is longer, the success rate of treatment is very low, and the mortality rate is very high. Once infected with AIDS, it is not only harmful to oneself, but also a fatal blow to the family.

So under what circumstances is it easy to be infected with AIDS?

1. Contact with blood or body fluids of AIDS virus carriers

Generally speaking, the incubation period of AIDS virus is long, and the daily physiological activities of AIDS carriers and normal people are not very different before the onset of AIDS virus, so it is difficult to determine whether they are AIDS carriers. At the same time, AIDS cannot be transmitted through air, and most of them are transmitted through blood. Shaking hands and eating with AIDS carriers have no great impact, but it is easy to be infected with AIDS when using instruments or household goods that can cause blood transmission with AIDS carriers.

2. Large amount of AIDS virus

There are three immune defense lines in the human body, namely the skin, mucosa, bactericidal substances in body fluids, immune organs, and immune cells. If the number of AIDS virus is too small, it will not be enough to break through the protection of skin and mucous membrane. If it enters the body fluid, because the number is too small, the bactericidal substances in the body fluid will be enough to dissolve it. People living with AIDS have more AIDS virus in their blood, semen and breast milk, which is enough to break the human immune defense line and lead to infection.

3. High activity of AIDS virus

The reason why AIDS virus cannot be transmitted through the air is that AIDS virus is weak in the atmospheric environment due to the lack of host survival ability. Without the support of nutrients, it will soon become inactive and die. Therefore, AIDS virus mostly resides in the body's blood and semen. Once the human body is exposed to the blood or semen of AIDS carriers, the highly active AIDS virus will defeat the human immune defense, causing AIDS infection.

4. The first line of defense, the skin and mucous membranes, are crushed

The first line of defense of the human body is a copper wall and iron wall to prevent most bacteria. As long as the first line of defense is not broken, it is difficult for the body to be infected by bacteria or viruses. Once the first line of defense of the body is broken, it will be infected by bacterial viruses and collapse, especially AIDS. The highly infectious AIDS virus will easily break through the remaining two lines of defense, thus infecting AIDS.
