About HIV & AIDS

‘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.

HIV is a virus that attacks the immune system and leads to AIDS if it isn’t treated.
HIV attacks certain cells in the immune system, stopping the body from fighting off illness.
There are three stages of HIV infection, but many people only show symptoms in the final stage.
There is currently no cure for HIV and AIDS. Research for a vaccine is showing some progress.
CD4 count? Viral load? Window period? They’re not as complicated as they sound!
