When there is a break in the oral mucosa, such as an ulcer, there is a risk of infection when body fluids containing a certain amount of HIV enter the mouth.
HIV is a chronic infectious disease caused by infection with the human immunodeficiency virus. HIV destroys a large number of immune cells and gradually causes the body to lose its immune function, which leads to easy infection of various diseases and a high death rate.
The main ways of HIV transmission are blood transmission, such as sharing intravenous needles and tattoos; sexual transmission, including all kinds of sexual contact between heterosexuals and homosexuals; and mother-to-child transmission, which generally includes intrauterine infection, delivery and breastfeeding transmission.
HIV is generally found only in the semen, blood, vaginal secretions and body fluids such as cerebrospinal fluid, amniotic fluid and breast milk of infected persons; other body fluids of a person, such as saliva, sweat and urine, contain almost no HIV. Therefore, ordinary daily life contact with HIV-infected people generally does not result in infection.
There is no cure for HIV, and it can only be detected and treated early to suppress the virus, improve the patient’s quality of life and prolong the patient’s life. In daily life, it is necessary to develop good habits, cleanliness, not promiscuity, reasonable use of condoms, not to share personal hygiene products with others.
