There are several stages of HIV, the first stages can include swollen glands in the throat, groin or armpit. In some cases there won't be any symptoms of HIV for many years. AID's symptoms will occur in the more advanced stages of HIV, this includes a very damaged immune system.

HIV (human immunodeficiency virus) attacks CD4+ T-lymphocytes (specialised white blood cells), which are crucial in the body's immune system. It enters the cell and makes many copies of itself, which then destroy the cell as they emerge through its membrane. This severely weakens the immune system, causing AIDS (acquired immunodeficiency syndrome).✯
