At the end of 2003, an estimated 1,039,000 to 1,185,000 persons in the United States were living with HIV/AIDS, with 24-27% undiagnosed and unaware of their HIV infection.1
1Glynn M, Rhodes P. Estimated HIV prevalence in the United States at the end of 2003. National HIV Prevention Conference; June 2005; Atlanta. Abstract 595.
In 2004, the estimated number of diagnoses of AIDS in the United States was 42,514. Adult and adolescent AIDS cases totaled 42,466 with 31,024 cases in males and 11,442 cases in females. Also in 2004, there were 48 AIDS cases estimated in children under age 13.
The cumulative estimated number of diagnoses of AIDS through 2004 in the United States is 944,305. Adult and adolescent AIDS cases total 934,862 with 756,399 cases in males and 178,463 cases in females. Through the same time period, 9,443 AIDS cases were estimated in children under age 13.
Please note: These totals include persons of unknown race or multiple races and person of unknown sex. Because totals were calculated independently of the values for the subpopulations, the totals in the tables below may not equal the totals above.
Of the estimated number of AIDS cases, person’s age at time of diagnosis were distributed as follows:
Age Estimated # of AIDS Cases in 2004 Cumulative Estimated # of AIDS Cases, Through 2004* Under 13: 48 9,443 Ages 13 to 14: 60 959 Ages 15 to 19: 326 4,936 Ages 20 to 24: 1,788 34,164 Ages 25 to 29: 3,576 114,642 Ages 30 to 34: 5,786 195,404 Ages 35 to 39: 8,031 208,199 Ages 40 to 44: 8,747 161,964 Ages 45 to 49: 6,245 99,644 Ages 50 to 54: 3,932 54,869 Ages 55 to 59: 2,079 29,553 Ages 60 to 64: 996 16,119 Ages 65 or older: 901 14,410
CDC tracks HIV/AIDS information on five racial and ethnic groups: white, black (African American), Hispanic, Asian/Pacific Islander, and American Indian/Alaska Native.
Estimated numbers of diagnoses of AIDS, by race or ethnicity:
Race or Ethnicity Estimated # of AIDS Cases in 2004 Cumulative Estimated # of AIDS Cases, Through 2004* White, not Hispanic 12,013 375,155 Black, not Hispanic 20,965 379,278 Hispanic 8,672 177,164 Asian/Pacific Islander 488 7,317 American Indian/Alaska Native 193 3,084
AIDS Cases by Exposure Category
Exposure is the way of reporting HIV cases by how they were spread. It is described by transmission categories. Six common transmission categories are male-to-male sexual contact, injection drug use, male-to-male sexual contact and injection drug use, heterosexual (male-female) 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 AIDS among adults and adolescents by exposure category. A breakdown by sex is provided where appropriate.
Exposure Category Estimated # of AIDS Cases, in 2004 Male Female Total Male-to-male sexual contact 17,691 – 17,691 Injection Drug Use 5,968 3,184 9,152 Male-to-male sexual contact and injection drug use 1,920 – 1,920 Heterosexual contact 5,149 7,979 13,128 Other** 298 279 577
Exposure Category Estimated # of AIDS Cases, Through 2004* Male Female Total Male-to-male sexual contact 441,380 – 441,380 Injection Drug Use 176,162 72,651 248,813 Male-to-male sexual contact and injection drug use 64,833 – 64,833 Heterosexual contact 59,939 99,175 159,114 Other** 14,085 6,636 20,721
The distribution of the estimated number of diagnoses of AIDS, among children*** by exposure categories follows:
Exposure Category Estimated # of AIDS Cases in 2004 Cumulative Estimated # of AIDS Cases Through 2004* Perinatal 47 8,779 Other** 0 664 *Includes persons with a diagnosis of AIDS from the beginning of the epidemic through 2004.
** Includes hemophilia, blood transfusion, and risk not reported or not identified.
***The term “children” refers to persons under age 13 at the time of diagnosis.
