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.

MMWR: HIV Surveillance - United States, 1981-2008

This report summarizes results of CDC’s analysis of data from the National HIV Surveillance System on the 30th anniversary of the HIV/AIDS epidemic. The report characterizes trends in HIV infection and AIDS in the United States during 1981-2008. Results indicate that in the first 14 years, sharp increases were reported in the number of new AIDS diagnoses and deaths reaching highs of 75,457 in 1992 and 50,628 in 1995. However with the introduction of highly active antiretroviral therapy, AIDS diagnoses and deaths declined substantially from 1995-1998, and remained stable from 1999-2008.

2011 Survey of Americans on HIV/AIDS

This report presents the eighth survey on HIV/AIDS, conducted by the Kaiser Family Foundation since 1995. It was conducted April 4, to May 1, 2011 among a nationally representative sample of 2,583 adults. Telephone interviews were conducted by landline and cell phone. The actual survey questions, responses, and number of people giving the specific response are provided, as well as comparisons with previous surveys.

HIV/AIDS at 30: A Public Opinion Perspective

This report presents results of the Kaiser Family Foundation's 8th national survey on HIV/AIDS since 1995. The survey examined public opinion about HIV/AIDS and the national efforts to prevent and treat it. It examined broad national trends in public opinion on the past several decades and took an in-depth look at the views and experiences of black Americans and young adults under the age of 30 years who have never known a world without HIV. It also focused on trends in reported HIV testing rates and experiences.

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
