AIDS / HIV Transmission Directory
HIV is transmitted when an infected person's bodily fluids enter another person's body. This usually happens through sex or drug use. It can also be passed from an infected mother to her baby during birth. Blood transfusions have an extremely small risk of transmitting HIV and are considered safe. HIV damages the immune system and hinders the body's ability to fight infections. HIV becomes AIDS when a person's CD4 T-cell count is below 200, but many people can live long lives with HIV.
