Some 33.4 million people were living with HIV as of 2008; 2.1 million of them were children under 15 years and 15.7 million were women. Every day, over 7,400 persons become infected with HIV and about 5,500 persons die from AIDS, mostly because of inadequate access to HIV prevention care and treatment services.

Sub-Saharan Africa remains the region most heavily affected by HIV, accounting for 67 per cent of HIV infections worldwide, 68 per cent of new HIV infections among adults and 91 per cent of new HIV infections among children in 2008.
