Estimated HIV Incidence and Prevalence

At a glance

Progress in HIV prevention continues with estimated HIV infections declining 12% overall in 2022 compared with 2018, driven by a decrease (30%) among people aged 13 to 24. By transmission category, estimated infections attributed to male-to-male sexual contact decreased 10% and infections attributed to male-to-male sexual contact and injection drug use declined 27%. By race and ethnicity, Black/African American people experienced a substantial decrease (18%) in estimated infections. Furthermore, estimated infections fell 16% in the South.

Estimated HIV infections in the United States over time

A change between 2018 and 2022 is assessed using a statistical test known as Z test for trend, with a P value of .05 used to determine if the difference is significant. Estimates for years 2020, 2021, and 2022 should be interpreted with caution.
*Among people aged 13 and older.

A change between 2018 and 2022 is assessed using a statistical test known as Z test for trend, with a P value of .05 used to determine if the difference is significant.

* Among people aged 13 and older.
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.
‡ Does not include infections attributed to male-to-male sexual contact and injection drug use.

Using this data

About the data

This page provides an overview of estimates of HIV incidence (number of new HIV infections), prevalence (persons living with diagnosed or undiagnosed HIV infection), and percentage of diagnosed infections among persons living with HIV (knowledge of status) in the United States. These data are essential to determining whether HIV prevention program efforts are reducing HIV transmission and may be used to monitor progress toward U.S. national goals outlined in the National HIV/AIDS Strategy and the Ending the HIV Epidemic in the U.S. (EHE) initiative.
