You can get AIDS from oral sex, but the relative probability is low. The AIDS virus (HIV) is mainly found in the blood, semen, vaginal secretions and other body fluids of HIV-infected and AIDS patients. When oral sex is performed, if there is damage to the oral mucosa, inflammation in the mouth, or if the oral mucosa is not intact, the HIV in vaginal secretions or semen will be transmitted to the body through the affected area, leading to HIV infection. Sexual contact with HIV-infected people, AIDS patients and high-risk groups should be avoided in daily life. When having sex, it is better not to have oral sex, and condoms should be used reasonably. In addition, it is necessary to strengthen exercise and enhance one’s own immunity.
