About HIV

HIV is a virus spread through certain body fluids that attacks the body’s immune system, specifically the CD4 cells, often called T cells. These special cells help the immune system fight off infections. Untreated, HIV reduces the number of CD4 cells (T cells) in the body.

Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. Opportunistic infections or cancers take advantage of a very weak immune system and signal that the person has AIDS. (HIV is the virus that causes AIDS.)

Locations of Virus, Symptoms & Spread

  • HIV can only be found in semen, vaginal and rectal fluids, blood, and breast milk of a person with HIV.
  • HIV is spread through unprotected vaginal or anal sex with someone who has it, through sharing needles, and through breastfeeding.
  • Initial symptoms of HIVare much like the flu:
    • Body aches
    • Fatigue
    • Fever
    • Headache
    • Sore throat
    • Swollen lymph nodes


The only way to know if you have HIV is to get an HIV test.
