UNAIDS is the Joint United Nations Programme on HIV and AIDS. Each year UNAIDS produces an AIDS epidemic update report on the latest developments in the global AIDS epidemic. The estimates are based on all available data, including surveys of pregnant women, population-based surveys, and other surveillance information. We have translated this data into a interactive worldmap. Have a look and get the latest insights. Want to go more into depth? Download the latest UNAIDS report below.

Sub-Saharan Africa remains most affected

Sub-Saharan Africa remains the region most heavily affected by HIV. There are an estimated 24.7 million people living with HIV this region, nearly 71% of the global total. The epidemic continues to be most severe in South Africa where one in four is living with HIV, followed by Nigeria where 13% of the population is living with HIV.

Even as access to antiretroviral therapy expands in sub-Saharan Africa, significant gaps remain. Only 45% [39-62%] of people living with HIV in this region know their status. The good news is that an estimated 86% of people who know their status are on antiretroviral therapy.

The total number of new HIV infections in sub-Saharan Africa has dropped by 33% among all ages between 2005 and 2013, down to 1.5 million [1.3 - 1.6 million] from the estimated 2.6 million [2.4 - 2.8 million] at the height of the epidemic in 1997. The number of AIDS-related deaths fell by 39% between 2005 and 2013.
