HIV (human immunodeficiency virus) is a virus that damages the cells in your immune system and weakens your ability to fight everyday infections and disease.
AIDS (acquired immune deficiency syndrome) is the name used to describe a number of potentially
life-threatening infections and illnesses that happen when your immune system has been severely damaged by
the HIV virus.
While AIDS cannot be transmitted from 1 person to another, the HIV virus can.
There's currently no cure for HIV, but there are very effective drug treatments that enable most people with the virus to live a long and healthy life.
With an early diagnosis and effective treatments, most people with HIV will not develop any AIDS-related illnesses and will live a near-normal lifespan.
