HIV/AIDS cannot be contacted through kissing. Kissing involves only saliva, which does not contain enough concentration of the virus to transmit HIV. However, HIV can be transmitted through blood transfusion, unsterilized injection, and sharing of needles. Manicure and pedicure, although involving sharp objects, have very low chances of transmitting HIV, especially when proper sanitation and hygiene practices are followed. It is important to note that HIV/AIDS is primarily transmitted through sexual contact, sharing of needles, and from mother to child during pregnancy, childbirth, or breastfeeding.
