This report summarizes the findings of an allocative efficiency study of Belarus' Tuberculosis (TB) response, which was conducted using the Optima-TB model in 2016-17. Epidemic projections made in the Optima-TB model suggest that with the current level of TB spending (US1.8 million in 2015) and the current allocation of resources to different TB response interventions, TB incidence, prevalence and deaths would continue to decline moderately in Belarus up to 2035, but 2020 national targets and global milestones as well as 2035 End-TB targets would be missed. Mathematical modelling analyses suggest that alternative program scale up scenarios and different service delivery modalities could improve outcomes of the TB response.
