About HIV Cluster Response

HIV cluster response is a critical component of the Centers for Disease Control and Prevention’s (CDC’s) Division of HIV/AIDS Prevention’s (DHAP) Strategic Plan 2017-2020’s overall strategy for bringing the nation closer to the goal of No New HIV Infections pdf icon[PDF – 1 MB]. Cluster response uses data routinely reported to health departments to identify communities where HIV may be spreading quickly. This information can then be used to identify gaps in prevention and care services and ensure that services reach the populations that need them the most.

Considerations for Implementing HIV Cluster Response

When a growing cluster for HIV transmission and its associated risk network are detected, whether through molecular surveillance or more traditional methods, partners can work together to prevent more transmission.  Learn more about HIV cluster response on CDC’s web page: HIV Cluster and Outbreak Detection and Response.
