Additional research priority areas that are not explicitly included in the Global Plan, as identified by researchers

Transmission dynamics	Which individuals are responsible for most tuberculosis transmission in high burden communities? How effective are different interventions in interrupting transmission?
Social determinants	How do structural and socioeconomic factors increase vulnerability to tuberculosis and how can they be addressed cost effectively?
Health systems and policy research	How can health systems be strengthened to better deliver quality services to at-risk populations (comorbidities, geographically isolated), thereby preventing generation of drug resistance? What measures should be taken to engage unregulated private healthcare providers? How do we increase evidence-based policy setting?
