Summary

This study follows 300 health workers in Cape Town, South Africa, who are at high risk of tuberculosis (TB) infection. Researchers will use a combination of existing and new tests every three months to track immune responses at the time of infection. The goal is to better understand why some people with TB infection develop active, life-threatening TB disease while others do not, which could improve prevention strategies.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this research could help identify which people with TB infection are at highest risk of developing active TB disease, allowing for better targeting of preventive treatments.
What could go wrong
This is an observational study, not a treatment trial. It aims to gather knowledge, not test a cure or therapy. The findings may not apply to all populations.
