Many countries are working to expand access to antiretroviral drugs for millions of people with HIV/AIDS. Uninterrupted and timely supplies of safe, effective and affordable antiretroviral drugs are needed. They must be dispensed correctly by health workers, and consistently taken by patients. A partnership between the World Bank and World Health Organization (WHO), in collaboration with the Global Fund for AIDS, TB and Malaria (GFATM), UNICEF, UNAIDS, and the American and French Governments is helping countries build capacity to procure and manage HIV/AIDS drugs and related supplies. This effort has helped support an increase in the number of people on antiretroviral drug treatment in low- and middle income countries, from 400,000 at the end of 2003, to about one million in June 2005.
