MMWR: HIV Infection — United States, 2005 and 2008

This report presents estimated numbers of HIV and AIDS diagnoses from the 42 areas (37 states and five US dependent areas) with confidential name-based HIV infection reporting since at least 2005. It also includes the statistics reported to CDC through 2008. The data presented in this report are subject to at least four limitations. First, HIV infection diagnoses might reflect both HIV incidence and testing patterns. Second, data were unavailable from certain states.

Estimated HIV Incidence in the United States, 2006–2009

This report in the form of a journal article describes a study to estimate the size and direction of the HIV epidemic in the United States from 2006–2009. The report updated earlier estimates of HIV incidence for 2006 based on additional data and methodological refinements and extended previous results with estimates for 2007, 2008, and 2009.

MMWR: Clinical and Behavioral Characteristics of Adults Receiving Medical Care for HIV Infection–Medical Monitoring Project, United States, 2007

This serial reports on the Medical Monitoring Project (MMP). The MMP was designed to be a nationally representative, population-based surveillance system to assess clinical outcomes and behavioral outcomes among persons with HIV infection who are receiving medical care in the United States. This report covers data collected during June 2007 to September 2008 for patients who received medical care in 2007. Findings indicate that in 2007, most persons with HIV infection who were receiving medical care were taking antiretroviral therapy (ART), and had some form of health insurance or coverage.

MMWR: Vital Signs: HIV Infection, Testing, and Risk Behaviors Among Youths - United States

In this report, the CDC used the National HIV Surveillance System data to estimate among youths, prevalence rates of diagnosed HIV infection in 2009 and the number of new infections in 2010. CDC used the 2009 and 2010 Youth Risk Behavior Surveillance System for 9th -12th grade students and the 2010 National Health Interview Survey for persons 18-24 years. Prevalence of diagnosed HIV was 69.5 per 100,000 youths at the end of 2009. Youth accounted for 12,200 (25.7 percent) new HIV infections in 2010.

Surveillance Brief: Terms, Definitions, and Calculations Used in CDC HIV Surveillance Publications

This information sheet explains terms, definitions, and methods of calculation used in HIV surveillance data, and the uses of these data. It defines unadjusted data, adjusted (estimated) data, AIDS diagnoses and deaths of persons with an AIDS diagnoses, and diagnoses of HIV infection and deaths of persons with a diagnosis of HIV infection. It also defines HIV incidence, persons living with a diagnosis of HIV infection or AIDS, incidence rate, prevalence rate, stage of disease, and transmission category.

HIV Among Youth in the US: Protecting a Generation

This information sheet provides data on youth and HIV in the United States. It states that 12,000 youth were infected with HIV in 2010, that 1 in 4 of the 50,000 people infected with HIV each year is 13 to 24 years old, the greatest number of new infections are among gay and bisexual youth, and nearly half of all new infections among youth are in African American males.

New HIV Infections in the United States, 2006 - 2009

This information sheet presents the latest estimates of new HIV infections (HIV incidence) in the United States released by CDC. These estimates are included in the CDC report, "Estimated HIV Incidence among Adults and Adolescents in the United States 2007-2010," which updates previously published estimates for 2007 through 2009. The new estimates indicate two trends: early signs of a decrease in new HIV infections among black women and an increase in new infections among young gay and bisexual men.

HIV and AIDS in America: A Snapshot

This information sheet provides an overview of HIV/AIDS in the United States, including the number of persons with the disease. It states that the number of new infections has remained stable, but that an estimated 50,000 persons who become newly infected every year is too high. It notes that nearly 15,000 people with AIDS still die each year in the United States. The information sheet provides statistics on the heavily affected populations by risk group and race/ethnicity.
