Poverty and AIDS Of the many ecological and biological factors contributing to widespread poverty, perhaps the most visible is the devastating AIDS pandemic. In 1981, the acquired immunodeficiency syndrome (AIDS) epidemic was discovered based on reports of a very rare pneumonia in a cluster of men in Los Angeles. Two years later the virus causing AIDS was identified as the human immunodeficiency virus (HIV). It was estimated in 2006 that over 25 million people have died from AIDS since that time. Across the globe today, there are more than 38 million victims of HIV/AIDS. Two to three million of these lose their lives each year; approximately one third are in sub-Saharan Africa. More than 4 million individuals were newly infected with the virus in 2005 alone (Joint United Nations Programme on HIV/AIDS [UNAIDS], 2006). HIV is most commonly spread through sexual contact, exposure to bodily fluids, and mother-to-child transmission (Centers for Disease Control and Prevention [CDC], 1999). In many of the less-developed nations, prostitution, reused needles as a result of substandard hygienic procedures, poor sanitation, and lack of access to condoms and preventive treatments contribute to an extraordinarily high infection rate (CDC, 2005). The economic impact of the AIDS pandemic is staggering. A large portion of the population of many countries in sub-Saharan Africa is unable to work, requires intensive medical care, and has a high mortality rate, leaving behind a generation of orphans who are vulnerable to be infected with HIV themselves (Greener, 2002). Current trajectories show a continued decrease in gross national product and gross domestic product as the infection rate rises (Over, 1992; Bell, Gersbach, & Devarajan, 2003).
