"The HIV/AIDS epidemic in African American communities is a continuing public health crisis for the United States. At the end of 2006 there were an estimated 1.1 million people living with HIV infection, of which almost half (46%) were black/African American [1]. While blacks represent approximately 12 percent of the U.S. population, they continue to account for a higher proportion of cases at all stages of HIV/AIDS?from infection with HIV to death with AIDS?compared with members of other races and ethnicities [2, 3]."
