AIDS Diagnoses

Diagnoses of Aids Patients

In 2008, the estimated number of persons diagnosed with AIDS in the United States and dependent areas was 37,991. Of these, 37,151 were diagnosed in the 50 states and the District of Columbia and 840 were diagnosed in the dependent areas.  In the 50 states and the District of Columbia, 27,543 AIDS diagnoses were among adult and adolescent males, 9,567 were among adult and adolescent females, and 41 diagnoses were among children under age 13 years.

The cumulative estimated number of AIDS diagnoses through 2008 in the United States and dependent areas was 1,106,391. Of these, 1,073,128 were diagnosed in the 50 states and the District of Columbia and 33,262 were diagnosed in the dependent areas.  In the 50 states and the District of Columbia, 851,974 cumulative AIDS diagnoses were among adult and adolescent males,  211,804 were among adult and adolescent females, and 9,349 were among children under age 13 years.

Estimated numbers resulted from statistical adjustment that accounted for delays in reporting to the health department (but not for incomplete reporting) and missing risk factor information, where appropriate.
Cumulative totals include persons of unknown race/ethnicity.  Because totals for the estimated numbers were calculated independently of the values for the subpopulations, the subpopulation values may not equal the totals.

Deaths of Persons with a Diagnosis of HIV Infection

Cause deaths of persons with a HIV infection

In 2007, the estimated number of deaths of persons with a diagnosis of HIV infection in the 37 States and 5 U.S. dependent areas with confidential name-based HIV infection reporting was 17,197. In the 37 states only, this included 16,651 adults and adolescents, and 8 children under age 13 years.

Deaths of persons with a diagnosis of HIV infection may be due to any cause.

Data include persons with a diagnosis of HIV infection regardless of the stage of disease at diagnosis. Estimated numbers resulted from statistical adjustment that accounted for delays in reporting to the health department (but not for incomplete reporting) and missing risk factor information, where appropriate. Because of delays in reporting of deaths, data are only available through the end of 2007. The exclusion of data from the most recent year allows at least 18 months for deaths of persons with a diagnosis of HIV infection to be reported.

Totals include persons of unknown race/ethnicity.  Because totals for the estimated numbers were calculated independently of the values for the subpopulations, the subpopulation values may not equal the totals.

Persons Living with a Diagnosis of HIV Infection

At the end of 2007, the estimated number of persons living with a diagnosis of HIV infection in the 37 states and 5 U.S. dependent areas with confidential name-based HIV infection reporting was 599,819. In the 37 states only, this included 577,452 adults and adolescents, and 2,919 children under age 13 years. 

Data include persons with a diagnosis of HIV infection regardless of the stage of disease at diagnosis. Estimated numbers resulted from statistical adjustment that accounted for delays in reporting to the health department (but not for incomplete reporting) and missing risk factor information, where appropriate.

Because of delays in reporting of deaths, data are only available through the end of 2007.  The exclusion of data from the most recent year allows at least 18 months for deaths to be reported and for these persons to be removed from calculations of persons living with a diagnosis of HIV infection.  

Totals include persons of unknown race/ethnicity.  Because totals for the estimated numbers were calculated independently of the values for the subpopulations, the subpopulation values may not equal the totals.

Diagnoses of HIV Infection by Transmission Category

Transmission Category of HIV Infection

 

Six common transmission categories are male-to-male sexual contact, injection drug use, male-to-male sexual contact and injection drug use, hetero sexual contact, mother-to-child (perinatal) transmission, and other (includes blood transfusions and unknown cause).

Following is the distribution of the estimated number of diagnoses of HIV infection among adults and adolescents in the 37 states with confidential name-based HIV infection reporting, by transmission category. A breakdown by sex is provided where appropriate.

Transmission Category	Estimated Number of Diagnoses of HIV Infection, 2008
	Adult and Adolescent Males	Adult and Adolescent Females	Total
Male-to-male sexual contact	22,469	-	22,469
Injection drug use	2,539	1,571	4,110
Male-to-male sexual contact and injection drug use	1,141	-	1,141
Heterosexual contact*	4,496	8,684	13,180
Other**	110	77	187

Heterosexual contact with a person known to have, or to be at high risk for, HIV infection. Includes hemophilia, blood transfusion, perinatal exposure, and risk not reported or not identified.

The distribution of the estimated number of diagnoses of HIV infection among children in the 37 states with confidential name-based HIV infection reporting, by transmission category, follows:

Transmission Category	Estimated Number of Diagnoses of HIV Infection, 2008
Perinatal	141
Other**	41

The term "children" refers to persons under age 13 years at the time of diagnosis. Includes hemophilia, blood transfusion, and risk not reported or not identified.

Diagnoses of HIV Infection by Race/Ethnicity

CDC tracks diagnoses of HIV

CDC tracks diagnoses of HIV infection information on seven racial and ethnic groups: 

American Indian/Alaska Native; Asian; Black/African American; Hispanic/Latino; Native Hawaiian/Other Pacific Islander; White; and Multiple Races.

In 2008, the estimated number of diagnoses of HIV infection in the 37 states with confidential name-based 

HIV infection reporting, by race or ethnicity was as follows:

Race or Ethnicity	Estimated Number of Diagnoses of HIV Infection, 2008
American Indian/Alaska Native	220
Asian	444
Black/African American	21,289
Hispanic/Latinoa	7,121
Native Hawaiian/Other Pacific Islander	33
White	11,778
Multiple Races	384

Hispanics/Latinos can be of any race.
