Statistics Overview

HIV Surveillance Report

HIV surveillance reports disseminate data about HIV—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,  2020; vol. 33.

  • Diagnosis of HIV infection: The term refers to people diagnosed with HIV infection, regardless of the stage of disease at diagnosis (stage 0, 1, 2, 3 [AIDS], or unknown), from all 50 states, the District of Columbia, and 6 dependent areas (American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, the Republic of Palau, and the US Virgin Islands).
  • HIV infection, stage 3 (AIDS): The term refers specifically to people 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 a person’s possible HIV risk factors and selecting the one most likely to have resulted in HIV transmission. For surveillance purposes, people with more than one reported risk factor 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 estimate: The number of people 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 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, 2020; vol. 33.

At the end of 2019, an estimated 1,189,700 people aged 13 and older had HIV in the United States,a including an estimated 158,500 (13%) people whose infections had not been diagnosed.b

In 2020, 30,635 peoplea received an HIV diagnosis in the United States and dependent areas.b

For more details on HIV infection and race/ethnicity, see CDC’s populations and surveillance fact sheets.

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, perinatal transmission, and other (includes blood transfusions and unknown cause).

b Transmission category is classified based on a hierarchy of risk factors most likely responsible for HIV transmission. Classification is determined based on the person’s sex assigned at birth. Data have been statistically adjusted to account for missing transmission category.
c Includes infections attributed to male-to-male sexual contact and injection drug use (men who reported both risk factors).
d Includes people who have ever had sexual contact with a person known to have, or with a risk factor for, HIV. Does not include men who have ever had sexual contact with both men and women.
e People aged 13 and over at the time of diagnosis.
f Includes hemophilia, blood transfusion, and risk factor not reported or not identified.

Data for 2020 should be interpreted with caution due to the impact of the COVID-19 pandemic on access to HIV testing, care-related services, and case surveillance activities in state and local jurisdictions.

At the end of 2020, there were 1,070,604 adults and adolescents with diagnosed HIV in the US and dependent areas.a

Because of delays in reporting of deaths, prevalence data for 2020 are preliminary and are based on deaths reported to CDC as of 2021. The exclusion of data from the most recent year allows at least 12 months for deaths to be reported and for these deaths to be factored into calculations of prevalence.

The profiles present the latest nationally representative data, as well as information about prevention and control programs that CDC supports nationally and in each state.
  • Statehealthfacts.org provides state-by-state information about new and cumulative HIV diagnoses, AIDS diagnoses, HIV testing statistics and policies, additional HIV-related state policies, Ryan White funding and other funding for HIV prevention, and AIDS Drug Assistance Programs (ADAP), including budget, client, and expenditure data from the Kaiser Family Foundation.

HIV continues to be a serious health issue for parts of the world. Worldwide, there were about 1.5 million new cases of HIV in 2020. About 37.7 million people were living with HIV around the world in 2020. An estimated 680,000 people died from AIDS-related illnesses in 2020. An estimated 36.3 million people have died from AIDS-related illnesses since the start of the epidemic. Eastern and Southern Africa is the region most affected by HIV worldwide, and accounts for about 45% of all new HIV infections. Other regions significantly affected by HIV include Asia and the Pacific, Western and Central Africa, Western and Central Europe and North America, and Latin America.
