HIV Cluster Detection and Response

HIV cluster detection and response (CDR) are the actions taken to prevent further transmission when a growing cluster of HIV transmission and its associated risk network are detected.

About HIV Cluster Detection and Response

CDR is a critical component of the federal initiative to End the HIV Epidemic by 2030external icon. CDR uses data routinely reported to health departments to identify communities where HIV may be spreading rapidly. This information can then be used to identify gaps in prevention and care services to ensure that services reach the populations that need them quickly.

Considerations for Implementing HIV Cluster Detection and Response

When a growing cluster of HIV cases and the associated risk network are detected, whether through molecular surveillance or partner services, partners can work together to prevent ongoing transmission. Learn more about CDR on CDC’s web page: HIV Cluster and Outbreak Detection and Response.

HIV Cluster Detection and Response Training

There is no CDC-supported training currently available for HIV Cluster Detection and Response. Technical assistance for HIV Cluster Detection and Response is available.

To request technical assistance:

  1. CDC’s directly funded health department and CBO partners may request technical assistance by submitting a request in the CBA Tracking System.
  2. Organizations not directly funded by CDC may contact their local health department for assistance in submitting a request.
