According to epidemiological surveys of AIDS, the main mode of transmission is actually through sexual contact, which accounts for 90% of all transmission methods. Besides sexual transmission, it can also spread through blood transmission and mother-to-child transmission. Blood transmission mainly refers to needle stick injuries, intravenous drug use, and there are also risks involved with eyebrow tattooing, ear piercing, and tattooing. If pregnant women with AIDS do not receive proper intervention, the virus can easily be transmitted to the newborn, and this is the concept of mother-to-child transmission.
