Slide 1 - Title:
Estimated Number and Proportion of AIDS Cases among
Female Adults and Adolescents, 1985–2002,  United States

The proportion of AIDS cases among women and adolescent girls (aged >13 years) increased from 7% in 1985 to 26% in 2002.

AIDS incidence among female adults and adolescents rose steadily through 1993, when the AIDS surveillance case definition was expanded, and leveled off at approximately 13,000 AIDS cases each year from 1993 through 1996. In 1996, incidence among women and adolescent girls began to decline, primarily because of the success of antiretroviral therapies.

From 1996 through 2002, an average of 11,000 cases of AIDS were diagnosed in female adults and adolescents each year.

Data for this slide were statistically adjusted for reporting delays. Slide 2 - Title:
Reported AIDS Cases and Rates Among Female Adults
and Adolescents, by Race/Ethnicity, 2002 
United States

In 2002, 67% of female adults and adolescents reported with AIDS were black; the rate was 49.1 cases per 100,000 black female adults and adolescents.

Although the numbers of cases reported among Hispanic and white female adults and adolescents were similar, the rate among Hispanic female adults and adolescents was more than 5 times that among whites.

Among all female adults and adolescents, the number of AIDS cases reported was lowest among Asians/Pacific Islanders and American Indians/Alaska Natives; however, the rate among American Indians/Alaska Natives was higher than among Asians/Pacific Islanders.

Slide 3 - Title:
Proportion of AIDS Cases among Female 
Adults and Adolescents, by Exposure Category, 2002
United States

CDC estimates that 68% of the 10,955 AIDS cases diagnosed among female adults and adolescents in 2002 can be attributed to heterosexual transmission: 15% of these cases are from heterosexual contact with an injection drug user and 53% from sexual contact with high-risk partners such as bisexual men or HIV-infected men with unspecified risks.

Of the cases in female adults and adolescents, 29% were attributed to injection drug use and 3% to other or unidentified risks.

Data for this slide were statistically adjusted for reporting delays and redistribution of cases initially reported without risk. Slide 4 - Title:
Proportion of AIDS Cases among Female 
Adults and Adolescents, by Exposure Category and Age at 
Diagnosis, 2002, United States

Most of the AIDS cases diagnosed in 2002 among females aged greater than 13 years were attributed to heterosexual contact.

Of cases among women aged 35-44 years, 33% were attributed to injection drug use, compared with 14% of cases in females aged 13-19 years, 19% in women aged 20-24 years, 24% in women 25-34, and 31% in women over 45.

Of females aged 13-19 years, 21% were exposed to HIV through perinatal transmission, and are included in the “other/not identified” exposure category.

Data for this slide were statistically adjusted for reporting delays and redistribution of cases initially reported without risk.

Slide 5 - Title:
AIDS Rates for Female Adults and 
Adolescents, Reported in 2002, United States

Rates of reported cases of AIDS per 100,000 female adults and adolescents are shown for each state and the District of Columbia. The highest rates were found in the District of Columbia, Maryland, New York, Florida, Louisiana, Delaware, South Carolina and New Jersey.

Rates were lowest in states in the Midwest. Nearly every state reported some AIDS cases among females in 2002.

The high rate in the District of Columbia should be interpreted with consideration that D.C. is more similar to a city than a state.

Rates were not calculated for states that reported fewer than 5 AIDS cases in females in 2002. Slide 6 - Title:
Estimated Number of AIDS Cases among Female Adults 
and  Adolescents Attributed to Injection Drug Use and 
Heterosexual Contact, by Region*, Cumulative through 2002 
United States

Most female adults and adolescents diagnosed with AIDS through 2002 were exposed through injection drug use and heterosexual contact with an HIV-infected partner. By the end of 2002, more than 146,000 AIDS cases among female adults and adolescents had been attributed to injection drug use and heterosexual contact.

Most cases have been among female adults and adolescents in the Northeast and South. More than half of the female adults and adolescents with AIDS attributed to injection drug use resided in the Northeast, and more female adults and adolescents there, in contrast to the other regions, were exposed through injection drug use.

In the South, the majority of female adults and adolescents with AIDS were exposed through heterosexual contact. Approximately 4 to 5 times more cases resided in the South compared to the Midwest and the West.

In the Midwest and West, more female adults and adolescents were exposed through heterosexual contact than injection drug use.

Data for this slide were statistically adjusted for reporting delays and redistribution of cases initially reported without risk.

Slide 7 - Title:
Reported AIDS Cases among Female Adults and 
Adolescents, by Region and Race/Ethnicity, 2002
United States 

Most reported AIDS cases among female adults and adolescents resided in the Northeast and the South; in these regions, most cases were among black, not Hispanic female adults and adolescents.

In the Midwest region, most cases were among black, not Hispanic female adults and adolescents. In the West, there was less disparity in the AIDS case counts among white, black, and Hispanic female adults and adolescents.

Data are not shown for Asian/Pacific Islander and American Indian/Alaska Native female adults and adolescents because the numbers reported in 2002, when stratified by region of residence, were low. Slide 8 - Title:
Female Adults and Adolescents aged 15-44 Years 
Living with HIV Infection (not AIDS) or with AIDS, 2002
United States


In 2002, there were 50,595 female adults and adolescents aged 15-44 years reported to be living with AIDS in the United States. 

An additional 42,047 female adults and adolescents in this age group were reported living with HIV infection (not AIDS) in areas that conduct name-based, confidential, HIV surveillance in adults and adolescents.

States with integrated HIV and AIDS surveillance data may be better able to target programs and services to reduce transmission to newborns.

The numbers presented here are an underestimate of female adults and adolescents living with HIV or AIDS, since many reside in states without integrated HIV/AIDS surveillance. In addition, there may be many infected females who have not been tested or not reported in areas with relatively new HIV infection surveillance systems.

In most states with HIV surveillance, the number of reported HIV infected female adults and adolescents who have not progressed to AIDS exceeds the number of female adults and adolescents with AIDS. Together these numbers indicate the burden of HIV and the number of persons in need of HIV-related medical and social services for themselves and to prevent transmission of HIV to their children.
