INTRODUCTION
HIV: Human Immunodeficiency Virus
AIDS: Acquired Immune Deficiency Syndrome
HIV is the virus that causes AIDS. HIV is different from most other viruses because it attacks the immune system. The immune system gives our body the ability to fight other infections. HIV finds and destroys a type of white blood cell (T cells or CD4 cells) that the immune system must have to fight disease.
AIDS is the final stage of HIV infection. It can take years for a person infected with HIV, even without treatment, to reach this stage. Having AIDS means the virus has weakened the immune system to the point at which the body has a difficult time fighting infections. When someone has one or more of these infections and a low number of T cells, he or she has AIDS. TRANSMISSION OF HIV
HIV can only be transmitted from directly from an infected patient to other people. HIV is only transmitted when an infected body fluid comes into contact with mucous membrane or broken skin (wounds, lesions, eczema) or if it enters directly into the bloodstream. HIV cannot cross healthy skin because it is protected by its outer layer, the stratum corneum.
MODES OF TRANSMISSION
Sexually transmitted: HIV infection is a sexually transmitted disease (STD). Infection takes place both through sperm and through vaginal fluids. A single sexual contact with someone who is seropositive can be enough to infect you. Oral-genital sex can also be dangerous.
Mother to baby transmission: A seropositive mother can pass HIV onto her baby during pregnancy, while giving birth, and while breastfeeding.
