This article discusses the progress made in HIV/AIDS treatment over the past 10 years, from the "3 by 5" initiative to achieve universal access to antiretroviral therapy (ART). It covers the current status of treatment worldwide, the role of the health sector in achieving universal access, and key findings and priorities for reducing mortality in low-income settings.

From "3 by 5" to Universal Access Kevin M. De Cock Director, HIV/AIDS Department
25 Years of AIDS Epidemiologic Notes and Reports: Pneumocystis Pneumonia --- Los Angeles In the period October 1980-May 1981, 5 young men, all active homosexuals, were treated for biopsy-confirmed Pneumocystis carinii pneumonia at 3 different hospitals in Los Angeles, California. Two of the patients died. All 5 patients had laboratory-confirmed previous or current cytomegalovirus (CMV) infection and candidal mucosal infection. Case reports of these patients follow. 10 Years of HAART

Priorities to reduce mortality of HIV/AIDS patients in low-income settings • Expand HIV testing for earlier diagnosis • Ensure essential package of care for HIV-infected patients, including TB screening and co-trimoxazole • Provide ART for Stages 3 and 4 disease as early as possible • Expand CD4+ testing for earlier initiation of ART • Abolish user fees
