2007 AIDS epidemic update + What should be the world's top priorities?

Out last week, the UN 2007 AIDS epidemic update lowered the UNAIDS and the World Health Organization estimates of how many people are living with HIV/AIDS worldwide. According to the report, about 33 million people worldwide are living with HIV/AIDS, compared with an estimate of nearly 40 million in 2006. The U.N. bodies said that better methods of data collection and increased data availability from countries show that HIV/AIDS is not quite as widespread as previously thought. Sub-Saharan Africa remains the most seriously affected region, with AIDS remaining the leading cause of death there. Downward trends in HIV prevalence are occurring in a number of countries, where prevention efforts aimed at reducing new HIV infections since 2000 and 2001 are showing results. In most of sub-Saharan Africa, national HIV prevalence has either stabilized or is showing signs of a decline (Figure 2). Côte d’Ivoire, Kenya and Zimbabwe have all seen declines in national prevalence, continuing earlier trends. In South-East Asia, the epidemics in Cambodia, Myanmar and Thailand all show declines in HIV prevalence.

When global warming has become the world's top priority, others are starting to question whether it should be the world's top priority, in opposition to fighting hunger, poverty and/or HIV. Although when can question his conclusions, economist Bjorn Lomborg makes a persuasive case for prioritizing the world's biggest problems, asking "If we had $50 billion to spend over the next four years to do good in the world, where should we spend it?" His recommendations - based on the findings of the 2004 Copenhagen Consensus - controversially place global warming at the bottom of the list (and AIDS prevention at the top).
