"As of the end of 2007, 33.2 million people were estimated to be living with HIV/AIDS worldwide, according to the latest data from the Joint United Nations Programme on HIV/AIDS (UNAIDS) and the World Health Organization (WHO). The estimates indicate that the global HIV/AIDS prevalence rate (the percent of people living with the disease) has leveled off, although the number of people living with the disease continues to increase. An estimated 2.5 million people became newly infected with HIV in 2007, and more than two million people died of AIDS-related causes in 2007. Women comprise half (50%) of adults estimated to be living with HIV/AIDS worldwide. Young people under the age of 25 are estimated to account for half of all new HIV infections worldwide."
