About the Six EHE Indicators

There are six EHE indicators: HIV incidence, knowledge of HIV status, diagnoses, linkage to HIV medical care, HIV viral suppression, and PrEP coverage.

Each indicator was chosen with specific public health goals in mind and in line with the four key strategies of the initiative: diagnose, prevent, treat and respond. Incidence measures our overarching goal of reducing new infections by 90% by 2030. Diagnoses, and Knowledge of Status are all key to identifying which individuals need to be linked to care, and represent important steps on the HIV Care Continuum. Data have shown that upon diagnosis, immediate linkage to care and treatment results in improved HIV outcomes, so it is important to track how these indicators change over time. Viral Suppression and PrEP use will have the greatest impact on reducing new transmissions if they are scaled up.

What are HIV Diagnoses?

HIV diagnoses refers to the number of people who have received an HIV diagnosis during a given time period, regardless of when they became HIV+. Some people may live with HIV for years before they receive an actual diagnosis, while others receive diagnoses soon after acquiring HIV. The baseline value of the HIV diagnoses indicator was calculated using National HIV Surveillance System (NHSS) data from January 1, 2017 through December 31, 2017 and reported to CDC through December 31, 2019. Number of reported HIV infections among persons aged ≥13 years that were confirmed through laboratory or clinical evidence during a calendar year. Data presented by quarter: Presentation of diagnoses data for a quarter includes cumulative counts of HIV diagnoses through the specified quarter of the calendar year. Data presented by quarter are preliminary. The reduction in HIV diagnoses in 2020 is likely due to disruptions in clinical care services, patient hesitancy in accessing clinical services, and shortages in HIV testing reagents/materials during the COVID-19 pandemic. Inclusion of 2020 data in trend assessments is discouraged.

About HIV Diagnoses Data

Data for the year 2023 are considered preliminary and based on data reported to CDC’s National HIV Surveillance System as of December 2023. Diagnoses data are preliminary through December 2023. Linkage to HIV Medical Care data are preliminary through September 2023 and PrEP Coverage data are preliminary through June 2023.

Data reported to the NHSS are considered preliminary until a 12-month reporting delay has been reached.
