Closing the gaps in childhood TB detection.

Globally, the gap between the number of children who develop TB and those who are detected and treated is narrowing, but it remains much wider than among adults. Several new diagnostic tests and approaches have been implemented recently, and more are anticipated in the development pipeline. We examine current tools and prospects for diagnostic testing and propose a framework to guide national TB programs and partners in addressing the TB treatment coverage gap among children while highlighting promising research and programmatic interventions.
