Hiv and AIDS can be spread by people sharing the same needles for drugs, this happens because the virus goes through the infected persons blood stream and when you use a needle it touches the infected blood the virus holds on to the needle and then it gets passed to the next person making them infected.
Blood contains the highest concentrations of the virus, so medical procedures involving blood, like blood transfusions, can transmit the virus; however, this is rare in the US. Getting a tattoo or a piercing can also transmit the virus if the needles are not properly cleaned; this is also very rare. Sharing needles for intravenous drugs will transmit the virus. Since breast milk also contains the virus, a mother can pass the virus to a nursing baby. She can also transmit the virus during pregnancy or during birth. Medications are available to lessen the chances of this kind of transmission happening
