HIV Cluster and Outbreak Detection and Response


HIV Care ContinuumHIV cluster and outbreak detection and response (CDR) is a public health strategy for identifying when and where HIV is quickly spreading.

An outbreak is defined as the occurrence of more cases of a disease than expected in a given geographical area, or among a specific group of persons over a particular period of time. Disease outbreaks can result in significant morbidity (Illness) and associated adverse health outcomes, disruption of services, and anxiety in a community.

A transmission cluster is a group of persons with HIV—diagnosed or undiagnosed HIV—who are connected by HIV transmission (the action of passing something from one person to another). Transmission clusters can represent recent and ongoing HIV transmission in a population, and prevention efforts could prevent new infections.

Transmission clusters can identify risk networks (groups of interconnected people) that are concerning because of ongoing transmission, poor outcomes, or other reasons, such as transmission in a particularly vulnerable or underserved population, or transmission of drug resistance.

A quick and effective response is crucial for saving lives.
