How HIV is Transmitted

People become infected with HIV through bodily fluids such as blood, semen, breast milk, and vaginal fluids. These fluids can be passed between people in a variety of ways, including having unprotected sex (oral, vaginal, or anal) or sharing needles. HIV can also be passed from mother to child during childbirth or through breast-feeding.

How HIV Effects Your Body

When HIV enters the body, it attacks the CD4 cells. The virus takes over the CD4 cells by making copies of itself within the CD4 cell. When this happens, the CD4 cell can no longer help your body fight infections. Instead, each HIV-infected cell produces more HIV in the body.




About AIDS

HIV and AIDS are often referred to interchangeably, but AIDS is much more severe and appears much further along in the disease process. However, because transmission of HIV leads to AIDS, it is important to note that HIV may be transmitted through sexual contact, body fluid contact or from mother to child.
