HIV/AIDS in 2004
The following are based on data from the 35 areas with long-term, confidential name-based HIV reporting.*
An estimated 4,883 young people received a diagnosis of HIV infection or AIDS, representing about 13% of the persons given a diagnosis during that year [1].
HIV infection progressed to AIDS more slowly among young people than among all persons with a diagnosis of HIV infection. The following are the proportions of persons in whom HIV infection did not progress to AIDS within 12 months after diagnosis of HIV infection:
81% of persons aged 15–24
70% of persons aged 13–14
61% of all persons
African Americans were disproportionately affected by HIV infection, accounting for 55% of all HIV infections reported among persons aged 13–24 [2].
Young men who have sex with men (MSM), especially those of minority races or ethnicities, were at high risk for HIV infection. In the 7 cities that participated in CDC’s Young Men’s Survey during 1994–1998, 14% of African American MSM and 7% of Hispanic MSM aged 15–22 were infected with HIV [3].
During 2001–2004, in the 33 states with long-term, confidential name-based HIV reporting, 62% of the 17,824 persons 13–24 years of age given a diagnoses of HIV/AIDS were males, and 38% were females.
