HIV is transmitted from person to person during specific activities when bodily fluids from an infected person, for example semen, vaginal fluids, anal secretions or blood, enter the body of another person (UNICEF, 2008). For transmission to occur, these fluids must come into contact with damaged or broken skin or mucous membranes inside the rectum, vagina, mouth or penis; by certain sexual behaviors or by using an infected needle or drug paraphernalia (NHS, 2014). Once infected, this virus gradually attacks and destroys certain cells of the body's immune system. The very system that protects and defends the body against disease or infection (The Well Project, 2015). HIV specifically targets CD4 cells or “helper” T cells and reduces their numbers, which weakens the immune system, making the body vulnerable and less able to fight infections (AVERTing HIV, 2015). If left untreated, HIV destroys so many of these cells that the immune system is too severely damaged, leaving the body vulnerable to opportunistic infections and HIV-related cancers. These infections would cause no reaction in a person with a normal immune system, but in someone infected with HIV, they can cause devastating illness (Aids.gov, 2010). This is the last stage of the HIV virus and is known as acquired immunodeficiency syndrome (AIDS). Unlike other viruses, the body cannot get rid of HIV: once caught, the person is infected.
