Quick Answer
HIV infection progresses through three stages if untreated: acute infection, chronic infection (asymptomatic), and AIDS. Modern antiretroviral therapy can stop progression, keeping viral load undetectable. People with undetectable HIV cannot transmit the virus to partners (U=U). HIV itself is distinct from AIDS, which is the advanced stage of untreated infection.
- HIV has two main types: HIV-1 (worldwide) and HIV-2 (mainly West Africa).
- There are four groups of HIV-1: M (main), N, O, and P.
- Within group M, subtypes include A, B, C, D, and others.
- Untreated HIV infection has three stages: acute, chronic, and AIDS.
- Antiretroviral therapy can suppress HIV to undetectable levels.
- Undetectable viral load means HIV cannot be transmitted sexually (U=U).

HIV is a retrovirus that attacks the body's CD4 immune cells. Without treatment, the virus replicates and gradually destroys these cells, leading to a weakened immune system. This progression is typically described in three stages. However, with modern antiretroviral therapy (ART), most people with HIV can stop the virus from multiplying, maintain a healthy immune system, and never progress to AIDS. Understanding the different types, strains, and stages of HIV helps clarify how the virus behaves and how treatment works.
