Number of people (all ages) living with HIV
Situation and trends
As of 2011, the global number of people living with HIV is 34.0 million [31.4 million–35.9 million], compared to 29.4 million [27.2 million–32.1 million] in 2001 – a 16% increase. This reﬂects the high numbers of people newly infected with HIV along with signiﬁcantly expanded access to antiretroviral therapy, which has helped to reduce the number of people dying from AIDS-related causes, especially since 2004–2005.
Sub-Saharan Africa still bears an inordinate share of the global HIV burden. Although the rate of new HIV infections has decreased, the total number of people living with HIV continues to rise. In 2011, that number reached 23.5 million
[22.1 million–24.8 million], 69% of the global total.
