Number of people (all ages) living with HIV
Situation and trends
In 2018, the global number of people living with HIV was 37.9 [32.7−44.0] million, compared to 24.9 million [21.5–28.9 million] in 2000. This reflects continued transmission of HIV despite reductions in incidence, and the benefits of signiﬁcantly expanded access to antiretroviral, which have helped to reduce the number of people dying from HIV-related causes, especially since 2004 when mortality peaked.
Sub-Saharan Africa remains most severely affected, with 1 in every 25 adults (3.9%) living with HIV and accounting for more than two-thirds of the people living with HIV worldwide. In 2018, that number reached 25.7 million [22.2–29.5] million.
