What this research studies

If you join, teams will map where TB spreads by combining TB genetics, where people live and move, and computer models to pinpoint hotspots. They will use blood RNA markers and sputum testing to look for active and subclinical TB, including people without symptoms. Screening will be focused in neighborhoods and groups identified as high-risk so testing can reach more undiagnosed cases. The goal is to use these data to guide targeted outreach and quicker treatment.

Who could benefit from this research

Good fit: People living in or near identified TB transmission hotspots in South Africa, including those who do not have TB symptoms, would be the best candidates to participate.

Not a fit: People who live outside the study areas or who are already diagnosed and on effective TB treatment are unlikely to directly benefit from enrolling in this project.

Why it matters

Potential benefit: If successful, this work could find and treat people who have TB but do not yet know it, reducing transmission and improving health in affected communities.

How similar studies have performed: Earlier studies show blood RNA markers and targeted screening can uncover hidden TB, but combining genomics, geospatial mapping, and predictive modeling for hotspot-based case finding is a newer approach.
