WHO’s 2022–2030 global health sector strategy on HIV aims to reduce HIV infections from 1.5 million in 2020 to 335 000 by 2030, and deaths from 680 000 in 2020 to under 240 000 in 2030.
Key facts
- HIV remains a major global public health issue,
- having claimed an estimated 44.1 million lives to date.

- and an estimated 1.3 million people acquired HIV.
- There is no cure for HIV infection.

- a manageable chronic health condition, enabling people living with HIV
- to lead long and healthy lives.
- WHO, the Global Fund and UNAIDS all have global HIV strategies
- that are aligned with the SDG target 3.3 of ending the HIV epidemic by 2030.
- In 2024, of all people living with HIV, 87% knew their status,

Overview
Human immunodeficiency virus (HIV) is a virus that attacks the body’s immune system.
Acquired immunodeficiency syndrome (AIDS) occurs at the most advanced stage
of infection.
HIV targets the body’s white blood cells, weakening the immune system.
This makes it easier to get sick with diseases like tuberculosis, infections and some cancers.
HIV is spread from the body fluids of an infected person, including blood, breast milk,
semen and vaginal fluids. It is not spread by kisses, hugs or sharing food.
It can also spread from a mother to her baby.
HIV can be prevented and treated with antiretroviral therapy (ART).
Untreated HIV can progress to AIDS, often after many years.
WHO now defines
Advanced HIV Disease (AHD) as CD4 cell count less than 200 cells/mm3
or WHO stage 3 or 4 event in adults and adolescents.
All children younger than 5 years of age living with HIV are considered to have
advanced HIV disease, regardless of clinical or immunological status.
