The total number of people diagnosed with AIDS in the USA is fast approaching one million. This total increases by more than 40,000 each year.
Around half of all people diagnosed with AIDS were probably infected with HIV through male-to-male sexual contact, while people exposed through heterosexual contact comprise around 16% of the total. However, since the beginning of the epidemic, the number of heterosexual infections has increased dramatically. According to CDC estimates, heterosexual contact led to about one third of new AIDS diagnoses and one third of new HIV diagnoses in 2003.
More than 18% of all adults and adolescents diagnosed with AIDS have been female. Among new AIDS diagnoses in 2003, and among new HIV diagnoses, this proportion was 27%.
Of the estimated 9,419 children under 13 years of age who have been diagnosed with AIDS, 8,749 (93%) were infected with HIV through mother-to-child transmission.

Notes
The latest statistics on AIDS & HIV in the USA were published in December 2004 by the US Department of Health and Human Services Centers for Disease Control and Prevention (CDC). The next data are due December 2005.
There is often a delay between the time of diagnosis of HIV or AIDS, or the time of death, and the time at which the event is reported. Moreover, this delay may differ among different categories of people. For this reason the CDC estimates the number of diagnoses, deaths and people living with HIV or AIDS by adjusting for reporting delays, taking into account the differences between categories. The CDC also redistributes cases into exposure categories if none was initially reported. No adjustment is made for incomplete reporting. On this page, all numbers are CDC estimates.
On this page "adults and adolescents" are defined as persons aged 13 years or more. The term "exposure category" refers to the most probable route of transmission of HIV infection. The term "male-to-male sexual contact" includes gay men, bisexual men and some men who consider themselves to be neither gay nor bisexual.
The HIV statistics presented on this page include only the 33 areas with a history of confidential name-based HIV reporting, as listed in our USA AIDS Summary. The AIDS statistics include all 50 states of the USA, the District of Columbia, Puerto Rico, Guam, the US Pacific Islands and the US Virgin Islands.
