An Exploratory Analysis of Cross-Country Access to Antiretroviral Treatment

This paper investigates some possible determinants of HAART coverage through exploratory regression analysis using data from World Health Organisation (2005), UNAIDS and the World Bank.   Following UNAIDS and the World Health Organisation, HAART coverage is defined as the number of adults on HAART expressed as a percentage of the number estimated to need it in each country. The bulk of the empirical work was conducted using HAART coverage as of December 2004.  However, in order to highlight how the international effort to improve access to HAART has changed the situation, regression analysis on HAART coverage as of June 2004 is also included at key points in the paper for comparative purposes.
