Indeed, tattooing is a risk factor for HIV infection, especially in informal institutions where tattoo equipment may be shared. If the tattooing equipment is not properly sterilized, there is a risk of HIV infection. Tattooing and other forms of needle injuries are also pathways for HIV transmission. However, the most common route of HIV transmission is through sexual transmission, often via unprotected sexual activities. There are also cases of mother-to-child transmission, which should be considered based on specific circumstances.
