Abstract
The 2000 International AIDS Conference in Durban, South Africa, focused the world's attention on disparities between rich and poor countries with respect to access to antiretroviral drugs. At that time, an estimated 7000 people in Africa had access to effective combination antiretroviral regimens. Though the number exceeds 100,000 today, it is still a far cry from the 8 million who are thought to require such therapy. In response, in 2003, the World Health Organization (WHO) launched an ambitious program termed “3 by 5” in an attempt to treat at least 3 million infected people by the end of 2005.
