Respond Pillar: HIV Cluster Detection and Response

The Ending the HIV Epidemic in the United States (EHE) initiative aims to reduce new HIV infections by 90% by 2030. The initiative includes four pillars: DIAGNOSE, TREAT, PREVENT, and RESPOND, and will scale up science-based strategies for each that can end the epidemic.

Responding quickly to potential HIV outbreaks can get vital prevention and treatment services to people who need them.

Real-time response systems are key to ending the HIV epidemic in the United States.
Cutting-edge public health approaches can pinpoint where there is rapid HIV transmission and can mobilize resources for HIV treatment and prevention.
HIV Cluster Detection and Outbreak Response uses data routinely reported to health departments to identify groups of people and communities that are experiencing rapid HIV transmission.

From December 2015-December 2019, 242 clusters were detected.

Transmission rates in clusters identified using CDC’s cluster detection approach are 8–11x as high as the U.S. average.
