About TRACE

Tracking with Recency Assays to Control the Epidemic (TRACE) aims to establish recent infection surveillance 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 ongoing 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: 

  1. 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 to inform HIV prevention interventions
  2. To identify geographic locations associated with testing recent on the RITA to inform HIV prevention interventions

As of 2022, TRACE is being implemented in the following countries:
