Tracking with Recency Assays to Control the Epidemic (TRACE) aims to establish surveillance systems to monitor and respond to the HIV epidemic, specifically focusing on recent infections among newly diagnosed PLHIV. As the global response moves closer to achieving 95-95-95, TRACE identifies and responds to the remaining pockets of transmission. Recent infection surveillance systems can more rapidly characterize the leading edge of the epidemic and allow countries to implement the right interventions, for the right populations, at the right time.
TRACE’s objectives are:
- To monitor trends in the proportion testing recent on the recent infection testing algorithm (RITA) among newly diagnosed PLHIV by select demographic and HIV risk variables (as available on HIV case reporting form) to inform targeted HIV prevention interventions
- To identify geographic locations associated with testing recent on the RITA to inform geographic prioritization of HIV prevention interventions
As a result of recency testing, at the population-level, routine epidemiological analysis can be conducted to monitor trends and identify locations and sub-populations associated with ongoing transmission to inform targeted interventions. At the individual-level, recency testing will allow data to be used to enhance counseling, triage index partner testing, and inform interventions for HIV-negative partners to stop transmission from occurring.
As of 2019, recency testing is being implemented in the following countries:
