TRACE

Tracking with Recency Assays to Control the Epidemic

THE TRACE INITIATIVE

TRACE – Tracking with Recency Assays to Control the Epidemic – was launched in countries nearing HIV epidemic control to establish HIV recent infection surveillance systems in routine HIV services to detect, characterize, monitor, and intervene on recent infection among newly diagnosed people living with HIV (PLHIV).

OUR GOAL

Use a rapid test for recent infection (RTRI) for recent infection to provide continuous epidemiological data on person, place, and time of newly diagnosed individuals to inform HIV prevention and control strategies. RTRIs pave the way for a HIV recent infection surveillance system as part of routine HIV testing services (HTS) to detect and characterize recent HIV infection among newly diagnosed
HIV cases.

WHAT IS RECENCY?

Rapid tests for recent HIV infection (RTRI) can differentiate between recent (i.e. in the last 12 months) and long-term HIV infections. Recently infected individuals have high HIV viral loads and are more likely to transmit the virus to others.

Recent HIV infection tests can provide 
real-time data about recent infections to identify
hot spots of current HIV transmission

Quick Facts about Recent HIV Infection Testing

Did you know that RTRIs can reveal in just 20 minutes if a newly diagnosed person living with HIV is recently infected or not?


 

 

When countries focus their efforts on testing a large number of persons and conducting index testing of partners, they can yield a higher number of recent infections.


Recenct HIV infection testing will allow us to monitor trends of recent infections over time as a proportion of persons at-risk and newly diagnosed persons.


Our Team

Key players of the TRACE Initiative include the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) TRACE Community of Practice, the University of California, San Francisco (UCSF), ICAP at Columbia University, and Ministries of Health and local implementing partners in each of the countries where recent HIV infection testing is being rolled out.
