According to the epidemiological survey on AIDS, the most common route of transmission is through sexual contact. Sexual transmission accounts for 90% of all routes of transmission, with the majority of female HIV infections being transmitted from males to females. Currently, 70%-80% of male HIV infections are contracted through homosexual activities. Apart from sexual transmission, infection can also occur through needlestick injuries, tattooing, intravenous drug use, eyebrow tattooing, ear piercing, and similar activities. Pregnant women with AIDS who do not undergo standard prevention may transmit the virus to their babies through mother-to-child transmission.
