back to top Global trends
The number of people living with HIV rose from around 8 million in 1990 to 34 million by the end of 2011. The overall growth of the epidemic has stabilised in recent years. The annual number of new HIV infections has steadily declined and due to the significant increase in people receiving antiretroviral therapy, the number of AIDS-related deaths has also declined.
Since the beginning of the epidemic, nearly 30 million people have died from AIDS-related causes.2

* Proportion of adults aged 15-49 who are living with HIV/AIDS
With around 69 percent of all people living with HIV residing in sub-Saharan Africa, the region carries the greatest burden of the epidemic. Epidemics in Asia have remained relatively stable and are still largely concentrated among high-risk groups. Conversely, the number of people living with HIV in Eastern Europe and Central Asia has more than tripled since 2000.
