2. Blood transmission: including: importing blood or blood products contaminated by HIV; Intravenous drug users use unsterilized needles and syringes contaminated by HIV; * * * Using other medical devices or household appliances (such as toothbrushes and razors with infected people) may also spread through the damaged parts, but it is rare.
Disinfection of syringes and needles is incomplete and incomplete, especially for children, it is more dangerous if one needle and one tube are not disinfected; The disinfection of dental instruments, delivery instruments, surgical instruments and acupuncture needles is not strict or not; Knives, needles and bathroom pedicure knife used for hairdressing, beauty (such as eyebrow tattooing and ear piercing) and tattoos are not disinfected;
Use a razor, razor or toothbrush with others; Transfusion of blood or blood products from blood donors who have never been tested for HIV antibody, and transfusion of bone marrow and organ transplant values under similar circumstances; When rescuing the bleeding wounded, the rescuer's own broken skin came into contact with the blood of the wounded.
3. Mother-to-child transmission: also known as perinatal transmission, that is, the mother infected with HIV spreads HIV to the fetus or baby before, during and shortly after delivery. It can be transmitted through the placenta, or through the birth canal during childbirth, or through breastfeeding.
Extended data:
Blood transmission is the most direct route of infection. It is very dangerous to import blood contaminated by virus and use syringes, acupuncture needles and tooth extraction tools contaminated by blood without strict disinfection. In addition, if you use unsterilized syringes with HIV-infected people, you will also be infected by the virus left by the needle.
If a mother is infected with AIDS, she probably infected her child during pregnancy, childbirth or breastfeeding.
