HIV is transmitted through three ways: blood, sexual contact and mother-to-child.
The blood, semen, vaginal secretions, and breast milk of HIV-infected people contain a large amount of HIV and are highly infectious.
Transmission through blood contact includes *** using unsterilized syringes and needles to take drugs, importing HIV-containing blood or blood products, and using contaminated blood-collection equipment or instruments.
Sexual transmission refers to the fact that HIV can be transmitted between heterosexuals and homosexuals through sexual intercourse, including vaginal, oral, and anal sex, etc. Sexual behavior that involves the exchange of bodily fluids carries the risk of HIV transmission. Mother-to-child transmission (MTCT) means that HIV-infected women can transmit the virus to their children through pregnancy, childbirth, and breastfeeding.
