    Abstract:
    OBJECTIVE: To estimate the potential direct cost of making triple combination antiretroviral therapy widely available to HIV-positive adults and children living in countries throughout the world. METHODS: For each country, antiretroviral costs were obtained by multiplying the annual cost of triple antiretroviral therapy by the estimated number of HIV-positive persons accessing therapy. Per capita antiretroviral costs were computed by dividing the antiretroviral costs by the country's total population. The potential economic burden was calculated by dividing per capita antiretroviral costs by the gross national product (GNP) per capita. All values are expressed in 1997 US dollars. RESULTS: The potential cost of making triple combination antiretroviral therapy available to HIV-positive individuals throughout the world was estimated to be over US$ 65.8 billion. By far the greatest financial burden was on sub-Saharan Africa. The highest per capita drug cost in this region would be incurred in the subregions of Southern Africa (US$ 149) followed by East Africa (US$ 116), Middle Africa (US$ 44), and West Africa (US$ 42). In the Americas, subregional data indicated the highest per capita drug cost would be in the Latin Caribbean (US$ 22), followed by the Caribbean (US$ 17), Andean Area (US$ 7), the Southern Cone (US$ 6), North America (US$ 6), and Central American Isthmus (US$ 5). In Asia and Europe the percentage of the GNP necessary to finance drug therapy was less than 1% in most countries examined. CONCLUSION: Our results demonstrate that the cost of making combination antiretroviral therapy available worldwide would be exceedingly high, especially in countries with limited financial resources. In 1997, an estimated 5.8 million people worldwide were infected with HIV, of whom 90% lived in developing countries, especially in sub-Saharan Africa. While antiretroviral therapy has been shown to prolong survival in people with HIV/AIDS, many of the countries with the highest rates of HIV infection have little or no access to antiretroviral therapy, for a number of reasons, including cost. Findings are presented from a study conducted to estimate the potential direct cost of making triple combination antiretroviral therapy widely available to all of the world's HIV-infected population. The potential cost of making such therapy available to HIV-positive people worldwide was estimated to be over US$65.8 billion, in 1997 US dollars, with the greatest expenditures needed in sub-Saharan Africa. The highest per capita drug cost in sub-Saharan Africa would be incurred in Southern Africa (US$149), followed by East Africa (US$116), Middle Africa (US$44), and West Africa (US$42). In the Americas, per capita drug costs would be US$22 in the Latin Caribbean, US$17 in the Caribbean, US$7 in the Andean Area, US$6 in the Southern Cone and North America, and US$5 in the Central American Isthmus. In Europe and Asia, the percentage of GNP needed to finance drug therapy was less than 1% in most countries examined. For each country, antiviral costs were determined by multiplying the annual cost of triple antiretroviral therapy by the estimated number of HIV-positive people accessing therapy. Per capita therapy costs were calculated by dividing the antiretroviral costs by the country's total population. The potential economic burden was calculated by dividing per capita antiretroviral costs by the gross national product (GNP) per capita.
