HIV attacks and damages CD4 cells (a type of T cell) in the immune system, weakening the body's ability to fight infections and disease. There are three stages of HIV infection: acute stage shortly after transmission, clinical latency or chronic stage, and AIDS. AIDS develops when the CD4 count drops below 200 cells per cubic millimeter. HIV is transmitted through bodily fluids like blood, semen, vaginal fluids, rectal fluids, breast milk, and can be transmitted through vaginal or anal sex, sharing needles, or from mother to child during pregnancy, labor, delivery or breastfeeding.
