Efforts to provide treatment for those living with HIV and AIDS continue to expand. As of December 2006, an estimated 2 million people were receiving antiretroviral therapy in developing regions. This represents 28 per cent of the estimated 7.1 million people in need.

Though sub-Saharan Africa is home to the vast majority of people worldwide living with HIV (63 per cent), only about one in four of the estimated 4.8 million people there who could benefit from antiretroviral therapy are receiving it.
