What this research studies

If you or someone you care for is in a prison in Central Western Brazil, researchers will offer portable digital chest x-rays read by automated software, collect samples for genetic testing, and follow people over time to see who develops TB. The team will look for TB even when people have no symptoms and will use genome data to trace how infections spread inside and between prisons. They will also use mathematical models to compare screening schedules and the addition of preventive therapy to find approaches that are both effective and affordable. Participation may involve a chest x-ray, giving sputum or other samples, and periodic follow-up while incarcerated.

Who could benefit from this research

Good fit: Ideal candidates are adults incarcerated in high-TB prisons in Central Western Brazil who can undergo chest x-rays and provide sputum or other samples for testing.

Not a fit: People not incarcerated in the targeted prisons, those without TB exposure, or those unable to undergo x-rays or provide samples would not directly benefit from participation.

Why it matters

Potential benefit: If successful, this work could lead to earlier detection and prevention of TB in prisons, lowering transmission, illness, and deaths.

How similar studies have performed: Automated x-ray screening and genomic tracking have shown promise in other settings, but using them together and proving cost-effective TB control in prisons remains largely untested.
