TB remains one of the world’s most stubborn infectious disease challenges, and the reason is not only the biology of the bacterium but also the sheer length of treatment.

Health systems have tried everything from directly observed therapy, in which a health worker watches each dose being swallowed, to pill counts, refill records, and digital pillboxes. Each approach carries costs, burdens, and blind spots. Now a research team reporting in PLOS Global Public Health has taken a careful, evidence-based look at a different strategy: a biochemical test that patients perform at home, photograph with a mobile phone, and upload through a companion app, allowing clinicians and treatment supporters to see objective evidence of recent medication ingestion.
