Can saliva kill AIDS?

In the years since the reform and opening up, people have become more and more open about sex. Due to sexual openness, people nowadays suffer from sexually transmitted diseases to varying degrees, and some even have AIDS. Not long ago, there was a rumor on the Internet that saliva can kill AIDS. Is this true? Let’s take a look at what the experts say.

HIV can indeed be detected in saliva, but the amount of virus is very small. HIV virus can cause transmission only when it reaches a certain amount. Someone has calculated that if you want the virus in saliva to reach an infectious dose, you would have to swallow more than 20 ml of saliva from an infected person at one time. In addition, American scientists have discovered that there is a protein called "secretory leukocyte inhibitory protease" in human saliva. This protein can effectively inhibit the HIV virus from infecting human immune cells in a test tube. Therefore, it is impossible to be infected with HIV through kissing, eating together, coughing or sneezing. There are no reports of infection through saliva in the current reports. However, when the infected person's semen is discharged into the mouth of a healthy person during a passionate deep kiss accompanied by bleeding gums or ulcers in the mouth, HIV may be transmitted through the oral mucosa into the blood.

After years of research, scientists have discovered that the level of HIV in the saliva of HIV-infected people is very high, and that cells susceptible to HIV exist in the human oral cavity. Based on this analysis, the possibility of HIV infection through the oral cavity should be very high. But why is it that when introducing the transmission routes of AIDS, almost everyone only says "There are three routes of HIV transmission: infection through blood, behavior and placenta." Why not say it is transmitted through saliva? This is because many studies have shown that the mechanical barrier effect of the oral cavity and the various HIV inhibitory components in saliva make the chance of saliva transmission very small.

1. Mechanical barrier function: The intact and undamaged oral mucosa can prevent the invasion of various microorganisms (including HIV). In addition, the saliva in the mouth has a flushing and diluting effect, which can flush the HIV into the stomach and then be killed by gastric acid.

2. Local immune response According to research, the oral mucosa can release a "secretory antibody - IgA". Once HIV invades, these antibodies hunt it down to protect the area and fight HIV.

3. Various ingredients that inhibit HIV. These effective substances mainly include: glycoprotein, defensin, emulsifier, thromboxane, salivary protein, etc.

After reading this article, I believe everyone has their own conclusion about the topic that saliva can kill AIDS that is circulated on the Internet. If you want to prevent AIDS from happening to yourself, you must keep yourself clean and not have sex with others casually. It’s best not to try ambiguous games like one-night stands easily.
