Fact 1: HIV (human immunodeficiency virus) infects cells of the immune system
Infection results in the progressive deterioration of the immune system, breaking down the body's ability to fend off some infections and other diseases. AIDS (Acquired immune deficiency syndrome) refers to the most advanced stages of HIV infection, defined by the occurrence of any of more than 20 opportunistic infections or related cancers.
Fact 2: HIV can be transmitted in several ways
Unprotected sexual intercourse, transfusions of contaminated blood, use of contaminated surgical equipment and other sharp instruments, mother-to-baby during pregnancy, childbirth and breastfeeding.
Fact 3: There are several ways to prevent HIV transmission
Practice safe sexual behaviours, get tested and treated for sexually transmitted infections, avoid injecting drugs, or if you do, always use sterile needles and syringes; ensure that any blood or blood products that you might need are tested for HIV.
