Key Impacts

Person-centered solution to repeat sputum collection increases TB diagnosis in Manila, Philippines

A decentralized approach to sputum recollection is patient centered and effectively increases TB diagnosis in an impoverished and densely populated area. This intervention highlights the importance of adaptable, patient-centered strategies in addressing public health challenges, which may be replicated elsewhere and be scaled up through local partnerships and capacity building of community health workers to conduct sputum collection.

Large burden of asymptomatic TB detected with chest X-ray and computer-aided detection software

During ACF, most treatment-naive people with BCTB report no TB symptoms. Symptom screening may not be cost-effective when systematically screening with CXR and CAD. In high-risk populations, symptom-agnostic screening strategies with CXR and CAD are important to detect people with asymptomatic TB, who possibly drive community transmission.
