UNAIDS Data Tables 2011

Gains continue to be made in the response to the global HIV epidemic. New HIV infections are falling, fewer people are dying of AIDS-related causes and more people with HIV are living longer.

There were 2.7 million [2.4 million–2.9 million] new HIV infections in 2010, down 21% from the peak of the global epidemic in 1997. HIV incidence has fallen in 33 countries, 22 of them in sub-Saharan Africa, the region most affected by the AIDS epidemic.
