Global prevalence among adults (the percent of people ages 15-49 who are infected) has leveled since 2001 and was 0.7% in 2021.

There were 38.4 million people living with HIV in 2021, up from 30.8 million in 2010, the result of continuing new infections and people living longer with HIV. Of the people living with HIV in 2021, 36.7 million were adults and 1.7 million were children under age 15.

Although HIV testing capacity has increased over time, enabling more people to learn their HIV status, about one in six people with HIV (15%) are still unaware they are infected.

Although there have been significant declines in new infections since the mid-1990s, there were still about 1.5 million new infections in 2021, or about 4,000 new infections per day. Recent data show that progress has slowed and is unequal within and between countries. Furthermore, the pace of decline varies by age group, sex, race, and region.

HIV remains a leading cause of death worldwide and the leading cause of death globally among women of reproductive age. However, AIDS-related deaths have declined, due in part to antiretroviral treatment (ART) scale-up. 650,000 people died of AIDS in 2021, a 52% decrease from 1.4 million in 2010 and a 68% decrease from the peak of 2.0 million in 2004.

Sub-Saharan Africa, home to two-thirds of all people living with HIV globally, is the hardest hit region in the world, followed by Asia and the Pacific. Latin America as well as Eastern Europe and Central Asia are also heavily affected.
