What is a transmission cluster and why is it important?

A transmission cluster is a group of HIV-infected persons (diagnosed or undiagnosed) who have a direct epidemiological connection related to recent or ongoing transmission in a population. Transmission clusters should signal a public health response to improve health outcomes and prevent infections by initiating testing activities, link or re-link HIV-positive persons into care, and provide prevention interventions for HIV-uninfected persons in the network.
