Whether or not you can get AIDS from a needle stick is related to whether or not the needle carries the HIV virus. Therefore, if you are pricked by a clean needle, you will not be infected with HIV, but if you are pricked by a needle that is infected with HIV, you may be infected with HIV. HIV is transmitted sexually, through blood, and from mother to child, and is found in body fluids such as blood, semen, vaginal secretions, saliva, tears, and breast milk. HIV can be transmitted through sexual contact, sharing needles, intravenous drug use, and the importation of HIV-contaminated blood or blood products. HIV-infected pregnant women can also pass it on to their babies through the birth canal and post-partum bloody secretions, and through breastfeeding. Therefore, if you are pricked by a clean needle, you will not be infected with HIV. If you suspect that you may be infected with HIV, you can go to a regular hospital for a checkup.
