‘HIV’ and ‘AIDS’ are not the same thing. It is important and helpful to understand the difference between them.
HIV is a virus that infects the body and attacks the immune system. If HIV is left untreated it can cause a range of symptoms.
People with very advanced HIV infection, whose immune systems have been almost totally destroyed, are said to have AIDS.
Lifelong treatment can keep HIV under control. This means people can live long healthy lives and stop worrying about infecting others.
