Statistics Overview

HIV Surveillance Report

HIV surveillance reports disseminate data about HIV and AIDS—for example, the number and population rates of HIV diagnoses, the number of people with HIV, and the number of people  receiving HIV medical care.

Unless otherwise noted, the following data are from CDC’s HIV Surveillance Report: Diagnoses of HIV Infection in the United States and Dependent Areas, 2017; vol. 29.

Definitions

  • Diagnosis of HIV infection: The term refers to persons diagnosed with HIV infection, regardless of the stage of disease at diagnosis (i.e., HIV infection Stage 0, 1, 2, 3 [AIDS], or unknown), from all 50 states, the District of Columbia, and 6 U.S. dependent areas (American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, the Republic of Palau, and the U.S. Virgin Islands).
  • HIV infection, stage 3 (AIDS): The term refers specifically to persons with diagnosed HIV whose infection was classified as stage 3 (AIDS) during a given year (for diagnoses) or whose infection has ever been classified as stage 3 (AIDS) (for prevalence and deaths).
  • Transmission category: The term for summarizing the multiple risk factors that a person may have had by selecting the one most likely to have resulted in HIV transmission. For surveillance purposes, persons with more than one reported risk factor for HIV infection are classified in the transmission category listed first in a hierarchy of transmission categories, and therefore counted only once. The exception is men who had sexual contact with other men and injected drugs; this group makes up a separate transmission category.
  • HIV prevalence: The number of persons with HIV at a given time regardless of the time of infection, whether the person has received a diagnosis (aware of infection), or the stage of HIV disease.

For more definitions and details about how HIV infection and AIDS data are tabulated, read the “Technical Notes” from the HIV Surveillance Report: Diagnoses of HIV Infection in the United States and Dependent Areas, 2017; vol. 29.

HIV Prevalence Estimate

Prevalence is the number of people who have HIV infection at a given time, such as at the end of a given year.

At the end of 2016, an estimated 1.1 million people aged 13 and older had HIV infection in the United States, including an estimated 162,500 (14%) people whose infections had not been diagnosed.a

Diagnoses of HIV Infection, by Transmission Category

CDC classifies HIV diagnoses into six transmission categories to which transmission may be attributed: male-to-male sexual contact, injection drug use, male-to-male sexual contact and injection drug use, heterosexual contact, mother-to-child (perinatal) transmission, and other (includes blood transfusions and unknown cause).

Following is the number of diagnoses of HIV infection in 2017 among adults and adolescents in the United States and 6 dependent areas, by transmission category. A breakdown by sex is provided, where appropriate.

International Statistics

HIV disease continues to be a serious health issue for parts of the world. Worldwide, there were about 1.8 million new cases of HIV in 2017. About 36.9 million people are living with HIV around the world. An estimated 940,000 people died from AIDS-related illnesses in 2017. An estimated 35 million people have died from AIDS-related illnesses since the start of the epidemic. Sub-Saharan Africa, which bears the heaviest burden of HIV and AIDS worldwide, accounts for 66% of all new HIV infections. Other regions significantly affected by HIV and AIDS include Asia and the Pacific, Latin America and the Caribbean, and Eastern Europe and Central Asia. CDC’s Global HIV website explains what CDC is doing in countries where HIV and AIDS have had great impact.
